Hi there, my 1007er had a clacking/schepper under the bonnet at some point. A short time later I was at the oil change and I was told that the Lambda hangs after Kat only loosely. So much to the clapping already before the oil change the car began to get problems with speed fluctuations in the stand (700-1100) and occasional starting problems (rubbing/sudden gas adoption). The Lambda probe was screwed in again, but nothing changed. In the error memory nothing is stored. Can the Lambda nevertheless have a defect, because it hangs loosely and always has been against everywhere during the ride and therefore these problems come? Further I often read something from throttle valve, coolant temperature sensor and LMM. But I found the first two but I can not find an LMM under my bonnet. Do I not have this one? LG
