Hello, now I also have a restless idle run. (9101/820) As a result, this: At the cold start the moose turns at about 1100 rpm. After driving or a few minutes it levels itself under the 1000 rpm (but not often) But very restless, sometimes +/-200 rpm and sometimes until shortly before going out, so that the battery symbol briefly lights up. Sometimes the DSA, sometimes the MKL and then for a long time again nothing. It also consumes quite a lot of gasoline (ca 10,2l combined) and it smells even after the foot tip of hitnen antipunk the problem. (which however is rather rare) What I have done before? LLR cleaned (possibly not correct?), DK was cleaned thoroughly (well, gas kicking or with the foot tip of hitnen antipunk is unfortunately not cleaned up).
