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.

plugs are cheapest and easiest , go for that first. Although I would have thought they got done when coils were changed?

more than likely HPFP

BMW just changed the ignition coils not plugs. Bought them and will change them myself and report back. Seems like you have to have warranty for a BMW these days

Local mechanic thinks its the low fuel pressure sensor.

Let me know how it goes mate. Would be interesting to see if its the same issue on 6 cylinder engines.
