N20 Engine Malfunction - Reduced Power
Friday driving home from work and sudden engine malfunction reduced power message came up on iDrive of 2013 xdrive28i. Engine shaking and could smell gasoline. Limped home and parked. Disconnected battery. Smelled like gas from exhaust. P0304 code misfire cylinder 4. On Saturday, took out spark plug, gasoline on plug, replaced plug and coil. Started car and same issues as above but a lot of white smoke coming from exhaust so I turned off ignition and disconnected battery again. Can you please help me on what else could be the problem?

So I replaced the fuel injector and that looked like it fixed the problem. No engine misfire, no gasoline smell, etc. Took the car out for a little spin to see how it runs and everything seemed fine. Saw a little bit of white smoke coming from exhaust, but by the time I got home it was gone. Ran the scan tool diagnostic just to see if there were any fault codes and I get the 2BC1 code, mixture control, fuel-air mixture too rich and depending on load condition, has to be reduced by 25 to 30%. Any idea what this could be? I programmed the new fuel injector code already. Should I change the oil since I was driving with a bad fuel injector for a short time?

Yes, you're right, when I drained the oil the smell of gasoline was very noticeable. The oil-gasoline mixture was also not as viscous as just oil so I'm glad I did that because all my efforts replacing the fuel injector would have gone to waste if I didn't simply change the oil afterwards and ended up ruining more parts in the engine. Now I'm not sure if I should keep this x1 or sell it for something different, because the N20 engine is prone to other failing parts from my understanding. |
