How it works and why it fails

EGR valve

The EGR valve feeds part of the exhaust gas back into the intake to lower combustion temperature and nitrogen oxide (NOx) emissions. Those gases carry soot, so the valve and its cooler get dirty over time, especially on diesels used for short urban trips.

What to do

Jerking, black smoke, loss of power or the engine warning light with limp mode are usually the first symptoms. A timely clean may be enough; if the valve is seized, it is replaced. If you are losing coolant with no visible leak, check the EGR cooler: an internal leak can damage the engine.

Problems with the EGR valve by engine

From most to least important (severity × frequency). Each page details the affected versions and years, symptoms, cost and how to check for it.

  1. 1Critical severityFrequency: Very frequentBMW B47EGR cooler leaks with risk of engine fireYes: the EGR valve cooler can suffer internal coolant leaks which, mixed with soot and oil, can reach combustion temperatures; BMW has launched several technical campaigns since 2018 to inspect and replace it because of the risk of engine fire.Repair (garage): €500–€1,500
  2. 2Critical severityFrequency: Very frequentBMW N57EGR cooler leaks with risk of engine fireYes: like the N47 and B47, the N57 is covered by BMW's service campaign for EGR cooler leaks, which can mix coolant with soot and oil to combustion temperatures. BMW checks free of charge the 6-cylinder engines built between July 2012 and June 2015 because of the fire risk.
  3. 3High severityFrequency: Very frequentOM651EGR and particulate filter clogging, and emissions software updatesThe particulate filter and EGR clog up with short journeys, as on any diesel with these systems. In addition, Germany's KBA required software updates on several models with this engine between 2018 and 2021 because of a function that reduced EGR outside a temperature range.Repair (garage): €800–€2,500
  4. 4Medium severityFrequency: Very frequentOM642Emissions defeat device (AdBlue/EGR) and software update campaignGermany's KBA found indications of emissions manipulation in cars with the OM642 engine (alongside the OM651): AdBlue dosing and the EGR changed between the test bench and the road. Mercedes-Benz denied it, but in 2018 it recalled hundreds of thousands of diesels in Europe.
  5. 5Medium severityFrequency: Very frequent2.0/2.2 D-4DEGR valve clogged with sootYes: the EGR valve clogs with soot very frequently across the whole 1AD/2AD D-4D family, especially with urban use and short journeys, and it usually causes a loss of power or the engine warning light to come on.Appears at around 45,000 km
  6. 6Medium severityFrequency: Very frequent1.9 TDIEGR valve clogged with carbonThe 1.9 TDI's EGR valve fills with carbon deposits, especially on short, urban journeys, and it is the fault that appears in the statistics for every model and output consulted, from the rotary pump to the unit injector.Repair (garage): €350–€450Appears at around 50,000 km
  7. 7High severityFrequency: Occasional2.2 / 2.4 / 3.2 TDCi (Puma)EGR valve and EGR cooler faults on the 2.2 TDCiThe sources point to the EGR valve (jerking from around 50,000 km, according to CarVerif) and the EGR cooler (coolant leaking into the oil, according to AutoTrader) as weak points of the 2.2; on the Transit, Haynes cites faults with the EGR valve and hoses.
  8. 8High severityFrequency: Occasional2.2 TD4 / SD4Coolant leak from the EGR valve coolerThe 2.2 diesel's EGR cooler can crack from vibration and lose coolant; Haynes documents it on the Freelander 2 and the owner of an Evoque SD4 suffered it at 150,000 km. The low coolant level message gives the warning.
  9. 9High severityFrequency: Occasional2.3 dCi (M9T)Clogged or broken EGR valve damaging the turboThe 2.3 dCi's EGR valve clogs with soot in urban use and, if it breaks, its fragments can damage the turbo. A French source cites bills of €1,200 to €2,300 for the EGR and turbo together.Repair (garage): €1,200–€2,300
  10. 10High severityFrequency: Occasional1.8 HybridEGR cooler leak into the intake and risk to the head gasketOn units built between 2015 and 2018, the EGR cooler can crack and let coolant pass into the intake; Toyota ran a campaign in 2021, documented on the Auris. On Prius III forums, a fouled EGR valve is also linked to one case of head gasket failure at very high mileage.
  11. 11Medium severityFrequency: Common1.6 HDiDirty EGR valve and EGR cooler leaksThe 1.6 HDi EGR valve gets dirty easily, especially in town use, and causes jerking and stalling at idle. On the 8V engines the EGR cooler also fails, consuming coolant with no visible leaks.
  12. 12Medium severityFrequency: Common2.0 TDIDirty EGR valve and EGR cooler leaksThe 2.0 TDI's EGR valve often fills with carbon, especially with short journeys, and causes smoke and loss of power. On the EA189, the EGR cooler can also lose coolant.Repair (garage): €100–€300
  13. 13Medium severityFrequency: Common1.5 dCiBlocked EGR valve on the early 1.5 dCiThe EGR valve often gets dirty and fails on the 65, 80 and 100 hp 1.5 dCi engines from before 2007; on later versions it is much less common. Cleaning it is often enough.
  14. 14Medium severityFrequency: CommonBMW N47Clogged or seized EGR valveYes, as on most diesels of its generation: the N47's EGR valve seizes or clogs with carbon, especially on cars used in town, causing an unstable idle, jerking and loss of power; it is not usually a serious fault if it is cleaned or replaced in time.Repair (garage): €400–€1,500
  15. 15Medium severityFrequency: Common1.3 MultijetEGR valve blocked by sootThe 1.3 Multijet's EGR valve easily accumulates soot on short urban journeys, causing an unstable idle, loss of power and the engine warning light. It is one of the most cited problems among owners of this engine.Repair (garage): €130–€400
  16. 16Medium severityFrequency: Common1.6 CRDiEGR valve blocked by carbon build-upAs on most diesels of its era, the 1.6 CRDi's EGR valve accumulates carbon with urban and cold-start use, especially beyond 80,000 km, and causes jerking when accelerating between 1,500 and 2,500 rpm and the engine fault light to come on.Repair (garage): €200–€450
  17. 17Medium severityFrequency: Common1.6 dCiBlocked or failed EGR valveThe 1.6 dCi EGR valve gets dirty and can stick or stop sealing, especially in cars used around town.

  18. 18Medium severityFrequency: Common1.6 TDIEGR valve clogged with carbon depositsThe EGR valve accumulates carbon deposits, especially on short urban trips, until it seizes and no longer seals or opens precisely. The engine loses power and jerks; cleaning the valve costs considerably less than replacing it.Repair (garage): €100–€1,000
  19. 19Medium severityFrequency: Common2.0 HDiEGR valve blocked by sootThe 2.0 HDi's EGR valve gets coated in soot and sticks, especially on the 107/120 and 136/138 hp versions; it causes jerking, limp mode and the engine warning light, although it can usually be solved by cleaning it.Repair (garage): €200–€350
  20. 20Medium severityFrequency: Common1.6 and 2.0 MultiJet IIEGR valve blocked by soot in urban useYes: the EGR valve builds up soot with urban use and short journeys, which causes loss of power and turns on the engine fault warning light. It is one of the most frequently cited faults of this engine in both the Jeep Renegade and the Fiat Doblò.Repair (garage): €200–€500
  21. 21Medium severityFrequency: Common1.9 JTD/Multijet and 2.4 JTDEGR valve blocked by carbonYes: the EGR valve accumulates carbon with urban use and short journeys, which turns on the engine warning light and causes loss of power.

  22. 22Medium severityFrequency: Common1.8 TDCiClogged or failing EGR valveThe 1.8 TDCi's EGR valve builds up carbon over time and can seize, causing jerking, loss of power and black smoke. It is a frequent and well-known fault on all models fitted with this engine.Appears at around 35,000 km
  23. 23Medium severityFrequency: Common1.6 / 2.2 i-DTECEGR valve clogged with soot and sensor failureYes: the i-DTEC's EGR valve can accumulate soot and seize, and its sensor or pipe can fail over time. It is documented mainly in the Honda CR-V (2007-2013 and 2012-2019 generations), with cases from 109,000 km.Appears at around 109,000 km
  24. 24Medium severityFrequency: Common1.7 CRDiEGR valve clogged with carbon depositsAs in most diesels of its generation, the 1.7 CRDi's EGR valve builds up carbon deposits with urban use and short cold journeys, which causes power loss and an uneven idle and can switch on the engine or emissions warning light.Repair (garage): €60–€350
  25. 25Medium severityFrequency: Common1.1 and 1.4 CRDiEGR valve clogged with carbon depositsAs on most diesels of its generation, the EGR valve on the 1.1 and 1.4 CRDi accumulates carbon deposits with urban use and can seize, causing jerking when accelerating and the engine warning light to come on.
  26. 26Medium severityFrequency: Common2.0 Ingenium diéselEGR fouling and AdBlue system faultsThe EGR valve gets clogged with soot as on any modern diesel, and the Ingenium diesel's AdBlue system fails fairly often according to several sources, with warnings that can end up preventing the engine from starting if they are not dealt with.
  27. 27Medium severityFrequency: CommonMZR-CDCarbon on the injectors, EGR valve and intakeUrban use and short journeys encourage carbon to build up on the injectors, EGR valve and intake of the MZR-CD, with loss of power and jerking; documented on the Mazda6 and Mazda3, on both the 2.0 and the 2.2.
  28. 28Medium severityFrequency: CommonSkyactiv-DCarbon build-up in the intake, EGR and injectorsUrban use and short journeys encourage carbon build-up in the intake manifold, EGR valve and injectors of the Skyactiv-D, with loss of power and uneven running; it is documented on the CX-5, the Mazda6, the Mazda3, the CX-3 and the CX-30.
  29. 29Medium severityFrequency: Common2.0 CDI (OM640)EGR valve clogged with sootYes: the EGR valve is the problem OM640 owners cite most. A specialist German source points to it as the thing to watch before any other, and a French source collecting 234 testimonies for the 109 hp version places it as the most repeated chronic defect, ahead of the injectors.
  30. 30Medium severityFrequency: Common2.2 CDI (OM646)EGR valve clogged or seized by sootYes: the EGR valve on the OM646 (and the OM611) accumulates soot over the miles, especially on short urban journeys, until it seizes. It is one of the faults owners cite most on several power versions, along with the injectors.
  31. 31Medium severityFrequency: Common2.5 dCi YD25EGR valve clogged with carbonThe 2.5 dCi's EGR valve clogs with carbon and usually turns on the engine warning light. Farmers Weekly puts the replacement part at about £150.
  32. 32Medium severityFrequency: Common1.6 CDTISuspected software shut-off of the EGR valve (emissions investigation)Between 2016 and 2018, Germany's KBA and the Frankfurt prosecutor's office investigated whether Opel switched off the EGR valve on its Zafira and Insignia diesels above certain conditions, increasing real-world NOx. Opel denied it and, according to the sources consulted, there is no record of a penalty or of a corrective campaign having been carried out.
  33. 33Medium severityFrequency: Common2.0 DTI and 2.2 DTIClogged or faulty EGR valveAccording to a German used-car buying guide, the EGR valve is the only notable weakness of this engine once it had matured in the Vectra C. In the Zafira A there are several owner testimonies of a faulty EGR valve, one of them before 30,000 km.
  34. 34Medium severityFrequency: Common2.0 CDTISoot build-up in the injectors and EGR valveLike many diesels of its generation, the 2.0 CDTI builds up soot in the injectors and the EGR valve, especially on short journeys and in town. An injector replacement has been documented in an Insignia from 105,000 km, and faulty injectors are also cited in an Astra J.
  35. 35Medium severityFrequency: Common2.0 CDTIGerman investigation into possible switching-off of the emissions treatmentBetween 2016 and 2018, Germany's KBA and the Frankfurt public prosecutor investigated whether Opel was switching off the emissions treatment on the Euro 6 diesels of the Cascada, Insignia and Zafira -models that also use this 2.0 CDTI-. Opel denied it; no final penalty or executed corrective campaign is on record.
  36. 36Medium severityFrequency: Common1.9 dCiEGR valve blocked by soot build-upThe EGR valve on the older 1.9 dCi engines (105, 110 and 120 hp) clogs with soot fairly often, especially in urban use; fiches-auto.fr includes it among the diesels most affected by this problem before 2010.
  37. 37Medium severityFrequency: Common2.0 dCiEGR valve blockageThe 2.0 dCi EGR valve gets dirty with carbon from the recirculated gases and can stick or stop sealing: it is the fault with the most reports in the Espace IV sheet (88 cases), with additional documented cases in the Laguna III and Qashqai.
  38. 38Medium severityFrequency: CommonD4/D5Clogged EGR valve or EGR cooler leaking into the intakeYes, in both D4/D5 families: the EGR gets dirty or clogged, and its cooler can lose its seal and leak coolant into the intake. It appears in the XC60, S60, V40 and V60, between 56,000 and 180,000 km, with limp mode and, in some cases, several valve replacements.
  39. 39Medium severityFrequency: Common1.4 TDIEGR valve clogged with carbonThe EGR valve builds up carbon, especially on short urban trips, until it seizes and stops sealing or opening precisely. The engine loses power and jerks; cleaning it costs considerably less than replacing it.Repair (garage): €100–€1,000
  40. 40Medium severityFrequency: Common3.0 TDI V6Faulty EGR valve and EGR coolerOn the first-generation EA896 engines the EGR valve and cooler often fail: Audi talks about around 15% of units compared with 1-2 in every 1,000 in the second generation (a figure cited by Wikipedia). The cooler clogs with soot and can lose coolant.
  41. 41Medium severityFrequency: Occasional2.2 JTDm Multijet IIClogged particulate filter (DPF) and EGR valve with depositsThe particulate filter and EGR valve of the 2.2 diesel are listed among its weak points in a German guide; the testimonials record excessive regenerations and replaced particulate sensors. Alfa Romeo attributes the intake valve deposits to the operation of the EGR.
  42. 42Medium severityFrequency: Occasional2.3 MultiJetEGR valve and throttle body clogged by carbon deposits and moistureThe 2.3's EGR and intake throttle body clog up with carbon, soot and, in the throttle body, moisture: the engine goes into limp mode, loses power and shows an EGR warning. On the dual-EGR Euro 6, the low-pressure cooler is added to the list. Almost all of this comes from forums and commercial websites.
  43. 43Medium severityFrequency: Occasional2.4 JTD / JTDm MultijetClogged or faulty EGR valve on the 2.4 JTD and JTDmThe EGR valve is the most-cited fault in the testimonies for the 200 hp 2.4 JTD of the Alfa 159: 24 mentions in 63, plus 8 in 36 for the 210 hp and 12 in 64 for the 156. It gets dirty or fails; RACE puts the cost of replacing an EGR between €130 and €800 on cars in general (not a price specific to this engine).Repair (garage): €130–€800
  44. 44Medium severityFrequency: Occasional2.2 i-CTDiClogged or faulty EGR valveThe 2.2 i-CTDi's EGR valve can clog with soot or fail with use, with emissions warnings on the dashboard; the available documentation is more limited than for the dual-mass flywheel or the turbo, with isolated cases from 137,000 km.
  45. 45Medium severityFrequency: Occasional2.0 CRDi (D4EA)EGR valve clogged with carbon with town drivingAs on most diesels of its generation, the EGR valve of the 2.0 CRDi D4EA appears as a typical wear point with town use in the Hyundai Tucson I buying guide, although without detail of specific symptoms for this engine.
  46. 46Medium severityFrequency: OccasionalOM656EGR valve clogged with soot after short journeysTwo OM656 guides include a dirty or clogged EGR valve among the typical problems, linked to short, urban journeys: loss of power and warning messages. A timely cleaning is usually enough; if the cooler is damaged, the repair gets more expensive. No failure-rate figures.
  47. 47Medium severityFrequency: Occasional1.8/2.2 DI-DSoot fouling of injectors and EGR valveOccasional: at high mileage, the common-rail injectors and EGR valve on the 1.8/2.2 DI-D can become fouled with soot, with jerking, loss of power and the engine warning light as the most commonly cited symptoms.
  48. 48Medium severityFrequency: Occasional2.2/2.5 dCiClogged EGR valveThe 2.2 dCi's EGR valve gets dirty with carbon from the gas recirculation and can stick: it is the fault with the most accounts in the Almera report, with additional cases, though in lower proportion, on the X-Trail.
  49. 49Medium severityFrequency: Occasional1.7 CDTISoot fouling of the injectors and EGR valveThis engine's EGR valve tends to clog with soot, according to a German buying guide focused on the Meriva A; there are also accounts of misadjusted or faulty injectors from 100,000 km on the Meriva and Astra with this engine.
  50. 50Medium severityFrequency: Occasional1.4 HDiEGR valve clogged with carbonThe EGR valve, which recirculates part of the exhaust gases to reduce emissions, can seize or clog up with the carbon those gases carry. It appears in a noticeable minority of the reports collected for the 68 hp version.
  51. 51Medium severityFrequency: Occasional2.0 BlueHDiEGR valve blocked by carbon depositsThe EGR valve on the 2.0 BlueHDi can get clogged with carbon deposits and stick, causing juddering and limp mode. Specialists place the greatest risk in the earlier 120 and 136/138 hp versions without AdBlue; at 150-180 hp the documented cases are in the minority.Repair (garage): €200–€350
  52. 52Medium severityFrequency: OccasionalSubaru bóxerImprecise injectors and sooty EGR valve on the EE20 dieselThe EE20's Denso injectors can work imprecisely and produce a knocking noise, and soot in the injectors and EGR valve can lead to expensive repairs; AUTO BILD cites 500-800 euros per injector in Germany.
  53. 53Medium severityFrequency: Occasional1.4 D-4DEGR valve clogged with sootYes, though with fewer cases than on other Toyota diesels: the 1.4 D-4D's EGR valve clogs with soot, especially on short trips, with cases from around 189,000 km on the Yaris and an inexpensive clean (around €60) that usually resolves it on the Corolla.Appears at around 189,000 km
  54. 54Medium severityFrequency: OccasionalD5 5 cilindrosEGR valve and EGR cooler clogged with carbonOn the D5 the EGR valve and its cooler accumulate soot, especially with short journeys; cleaning or replacing them costs between €350 and €700 in Spain according to an industry article.Repair (garage): €350–€700
  55. 55Medium severityFrequency: Occasional1.2 TDIEGR valve blocked by carbon depositsThe EGR valve builds up carbon deposits, especially on short urban journeys, until it seizes and stops sealing or opening precisely. The engine loses power and judders; cleaning it costs considerably less than replacing it.Repair (garage): €100–€700
  56. 56High severityFrequency: RareBMW B57EGR cooler leaks on the B57 (limited action on the 540d xDrive)Unlike the N47 and N57, the B57 was left out of the big EGR campaigns of 2018 and 2021; a specialist garage cites only one action in 2022 for the 540d xDrive and another limited one in 2024. The fault exists but is uncommon.
  57. 57High severityFrequency: Rare2.3 MultiJetFractured EGR pipe with a risk of short circuit and fireOn some Euro 6 Ducato built between February 2016 and September 2017, the EGR pipe could break and touch the alternator, with a risk of short circuit, loss of battery voltage and, according to the European alert, fire. Fiat checked it in a preventive campaign.
  58. 58Medium severityFrequency: Rare1.5 / 2.0 EcoBlueEmissions system warnings (AdBlue/EGR) and injector wearOn the Ford Focus IV and Kuga III, generations that now only use EcoBlue, some owners report, occasionally (not in the majority), AdBlue system warnings or injector failures. It is a small sample, and we have not found that Ford has announced a campaign of its own for the EcoBlue for this reason.
  59. 59Low severityFrequency: OccasionalVM Motori 2.8 and 3.0 CRDEGR valve and intake clogged with sootWith short journeys, the EGR valve and intake of the 2.8 and 3.0 CRD accumulate sticky deposits that cause jerking, black smoke and uneven running. It is usually fixed by cleaning; if not, the valve has to be replaced.Repair (garage): €150–€600
  60. 60Low severityFrequency: Occasional2.5 TDI R5EGR valve clogged with carbonThe 2.5 TDI's EGR valve can clog with carbon and trigger engine management warnings. It is a common fault on the T5 diesels, but without frequency figures.

OBD fault codes with the EGR valve

The codes the ECU usually stores when this part fails: what they mean, causes and what to check.

Frequently asked questions

Can the EGR valve be cleaned, or does it have to be replaced?

It depends on the valve. Older mechanical ones often work again after a good clean: the carbon is scraped off and a solvent is left to soak in, up to an hour of work. On modern electronically controlled valves, if the fault is electronic, it is advisable to replace it with a new one rather than a used one.[9]

Is it legal to delete the EGR valve?

No. Deleting it is an illegal modification, because the car no longer operates under the conditions it was type-approved for and emits more nitrogen oxides. It can mean failing the ITV (the periodic technical inspection in Spain), which already reads the control unit through the OBD port and detects that the system is not working.[19]

Which engines have the most faults with the EGR valve?

By severity and frequency, the BMW B47 (EGR cooler leaks with risk of engine fire, critical severity), the BMW N57 (EGR cooler leaks with risk of engine fire, critical severity), the OM651 (EGR and particulate filter clogging, and emissions software updates, high severity), the OM642 (emissions defeat device (AdBlue/EGR) and software update campaign, medium severity), the 2.0/2.2 D-4D (EGR valve clogged with soot, medium severity) and the 1.9 TDI (EGR valve clogged with carbon, medium severity). In total we have documented 58 engines with faults with the EGR valve.

How much does it cost to repair a fault with the EGR valve?

It depends a lot on the engine or car. At an independent garage, from €60 to €2,500, including VAT, based on the 20 faults with a documented cost. The most expensive is EGR and particulate filter clogging, and emissions software updates (OM651).

What symptoms does a fault with the EGR valve cause?

The most frequently cited in the documented faults: gradual loss of power, engine fault warning light (check engine), jerking or juddering when accelerating, black smoke when accelerating, coolant loss with no visible leak and sudden loss of power (limp mode).
