On the 2007-2014 MINI GP, the N14 and N18 engines fitted to the GP1 and GP2 are well-documented for crankcase ventilation oil separator (CCV) failure, where the plastic separator housing cracks or the internal membrane fails. A failed CCV causes excessive oil to be drawn into the intake manifold and combustion chambers, resulting in visible blue smoke from the exhaust and abnormally high oil consumption between service intervals. MINI issued TSB SI B11 06 11 addressing this concern on N14 and N18 engines.

This issue also affects: BMW 3 Series, BMW M3, BMW X6

Common Symptoms

  • Blue or grey smoke from exhaust especially on startup
  • Oil consumption exceeding 1 quart per 1,000 miles
  • Oil residue visible in intake tract or intercooler pipes
  • Rough idle due to oil fouling throttle body
  • Check engine light with lean or misfire codes

How to Fix

Replace the oil separator/CCV unit (OEM part 11617533400 for N14, 11617588885 for N18). The repair also requires cleaning the intake manifold and throttle body of oil residue. Parts cost $80-$180; total repair including labor typically $250-$600 at an independent specialist.

Typical repair cost:$250 - $600
