Smells like burning plastic
Looking for some help with my 2015 328i GT xdrive. For the past week, there has been an occasional smell like melting wax and burning plastic/rubber. I did the first logical thing by replacing the drive/serpentine belt last night. The car has 80K miles on it, so it was due for a belt anyway. Still stinks. I took off the engine cover and the thick foam layer underneath it expecting to find something melting....no dice. I saw a puff of smoke at idle from the passenger side and it looks like SOMETHING is leaking and dripping on the exhaust. I'm 99% sure it's not fuel as I would smell gas under the hood and my car would be on fire. I did replace the high pressure fuel pump a few moths ago but it looks OK.
What's dripping on the exhaust?!?!?!?! It's hard to pinpoint because it only happens maybe once every 5-10 minutes. |

It is indeed oil. I found the spot and used a piece of white paper on a long stick and waited for a drip. Oil dripping directly on to the exhaust. Head gasket?? At 80k miles?

That will be cheaper than a head gasket. If that is the culprit, I may keep the car.....would have sold it if it was a head gasket. I'll get the dye today. Thanks for the reality check....I should have thought of the valve cover.

I found what appears to be a decent BMW shop in Denver. I'm dropping off the car on Monday and will ask them about that. I turn my own wrenches most of the time, but this is something for a pro.

BimmerHaus in Broomfield is a good option. I know the owners. Very honest and straightforward people. Happen to have a ton of national championships in autocross between them. They also help those less fortunate out with their time and money. Good people.
