PSA 2.0 16v EW10 and 2.2 16v EW12 (gasolina, 1999-2010)Urgency: Garage soon

Jerking or juddering when accelerating in the 2.0 and 2.2 16v EW10/EW12 engine: causes

In the 2.0 and 2.2 16v EW10/EW12 engine, 1 documented fault may be the cause: faulty ignition coils.[1]

What to do now

Garage soon

Check whether any warning lights are on and ask for a fault code read-out. If the jerking comes with a flashing engine warning light, slow down and go to a garage.

What it means

The car moves in fits and starts or hesitates when you press the accelerator. It may be caused by misfires, injectors, sensors, the EGR valve or, on automatic gearboxes, the clutch.

  1. Source for the symptom[1]

Other common causes: jerking

Besides the documented faults of the 2.0 and 2.2 16v EW10/EW12, these are the most common causes on any car according to the sources.

  • Dirty, worn or faulty injectors[3][4][5]Common
  • Worn spark plugs, ignition coils or glow plugs[4][6][7][8]Common
  • Fuel supply: fuel filter, pump or poor-quality fuel[3][4][6][7]Common
  • Air flow meter, air filter or throttle valve[3][4][7][9]Possible
  • Blocked EGR valve, catalytic converter or particulate filter[4][6][7]Possible
  • Faulty turbo[3]Possible

What to check first

  1. Note when it happens: only when cold, at constant speed, on a climb or under load, at low revs or just as you release the clutch. Autonoción and RMotion use precisely that moment to narrow down the cause.[7][10]
  2. Rule out the simple things: if it started shortly after refuelling, suspect the fuel, and if you are in a gear that is too high for the speed, change down to see whether it goes away.[4][10]
  3. See whether the engine warning light is on: according to Autonoción, a check engine light together with jerking more likely points to an ignition coil or a sensor.[7]
  4. Ask for a code read-out with a diagnostic scanner before replacing parts: RMotion warns that parts should not be replaced on symptoms alone, because the same symptoms come from different faults.[8][10]
