Hi All,

Newbie here. I own a 2010 135i with 85k miles on it. When I hit 3k rpm the yellow engine light comes on and the car goes into reduced power mode.

I was driving it about 2 days ago and heard a pop as I accelerated. Since then I have had this issue.

Any help is greatly appreciated.

Thanks!

Hi' it could be either ignition coil, plug or vanos malfunctioning. Worst, could be DME servomotor. Have it check by qualified mechanics then & don't get fooled.

Thanks for the fast reply. Is there a way to check for issues with those? The car starts, drives, idles just fine. It only shows up if I get the revs over 3k.

I took it by three places yesterday and none of their machines could read the codes. I am sure that the dealer will be ski high to fix any of these.

Thanks in advance.
