Hi, I have actually same problems for one week, I have discussed this matter elsewhere but still haven't found solution. In my case engine is "lumpy" for first 5 minutes before the engine reach approx. 30deg. than it slowly disappears. When I checked MB013 in 001 Engine in VCDS my 1st and 3rd cylinder values jumps around 1.5 to 2.99mg/str which are not optimum. I have been advised to remove rocker cover and clean/tighten injector loom which in most cases cause idle problems on Tdi's.

Hi there

Firsly check that all the glow plugs are working, as they are still required after starting engine, if one or two are not working that will give a misfire till engine warms
