BMW N13 (N13B16) version

With caution

It shares with the other N13 versions the timing chain and tensioner wear flagged by BMW in its 2013 technical bulletin, as well as the oil consumption and injector carbon build-up documented for the whole Prince family.[1][2]

What changes in this version

Highest-output step of the initial range, with 170 hp (125 kW) and 250 Nm; it powered the 118i from the launch of the F20 in 2011 and, according to German Wikipedia, was also retained after the 2015 facelift.[1][3]

Engine codes of this version: N13B16.

Faults of the N13B16 engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1Critical severityFrequency: CommonTimingTiming chain and tensioner wearYes: in 2013 BMW issued a technical bulletin on timing chain and tensioner wear on the N13, an engine related to PSA's 1.6 THP. The chain proved more durable than on the N43 it replaces, but the German workshops we consulted still point to it as a weak point.
  2. 2Medium severityFrequency: CommonLubricationHigh oil consumptionYes: like the rest of the Prince family (EP6/THP), the N13 can use oil between changes; the German publication Gebrauchtwagenberater.de documents extreme cases of up to 1 litre per 1,000 km and expressly cites the 114i, 116i and 316i among the affected models.
  3. 3Medium severityFrequency: OccasionalInjectionHigh-pressure fuel pump (HPFP) failureThe high-pressure pump that feeds the N13's direct injection can fail. English Wikipedia generically documents several cases of extended-warranty replacement within the Prince family, with no specific figures or N13-specific recall.
  4. 4Low severityFrequency: CommonInjectionCarbon build-up on direct injection injectorsYes: being direct injection, the N13 can build up carbon on the injectors over time, with loss of power and higher consumption. Gebrauchtwagenberater.de places this problem on almost the whole Prince family, apart from PSA's naturally aspirated EP6/EP6C variants.
