Engine light and codes

QuintanaRafael · 12-13-2018, 04:35 PM

I recently bought a 2008 335i and engine light went on so I took it to a friend and got the code. There was 5 . 29F4,29F5,3100,2A87and 30FE . I noticed there was some black smoke coming from the tailpipe. I'm taking it to the dealership to have it diagnosed. My question is has anyone had this issues and was it the valve stem that caused this issue? Please help I will take any advise. Thanks

Did you use the search function at the top of the page...there’s loads of info on what to do. Some of those are “easy” fixes...some less so.

Honestly if you’re not a do it yourself type person this car is going to get very expensive for you very quickly.

3100 is just saying that the CEL was triggered. 30FE is over boost. I just had this on mine, it turned out to be the boost solenoids on mine. Don't know the rest.
