320i Rough on idle, EML flash, Codes
Got myself a 2009 320i a month ago, drives beautifully but car shakes violently at idle especially in cold mornings.
Obviously heard about the infamous coil issues and BMW changed them for me for free. New coil pack did not make any difference at all. Today the shaking got even worse, RPM was all over the place and the engine management light flashed and then went off. Anyone experienced a similar problem? Checked codes and got: 2AAF - Fuel pump, plausibility 29DC - Cylinder injection cutout 2A2D - Fuel low pressure system fuel pressure 29D0 - Combustion misfire on cylinder 4 Mechanic suspecting spark plugs. What do you think guys? thanks. |

My car idled rough at start up as it got colder, but not to the extent you describe and didn't throw any codes. Dealer replaced all 3 injectors in bank 1 and it's smooth now fwiw.

I had this issue, the low fuel pressure sensor needed replacing. It was fine for about 4 weeks, the I needed to replace one of the fuel injector.
