Hello dear elk friends, some time ago my engine lamp lit up again. it wasn’t ignition coils or candles this time! I drove a few hundred km so on without problems. suddenly on the highway he started to jerk like crazy faster than 100 km/h and without giving big gas didn’t go any more. ok at home spark plugs out and hoppla all black! I cleaned them and deleted the error and it went again. however after some time the motor light came back. ok have me a n eue lambdasonde put in. 30 km driven and hoppla light went on again! I deleted the error again. however he consumes far too much spret and he has not really steam any more he comes at his speed, but it seems to me, as if one of the cars is stuck from behind :-). my kfz workshop means it can be something on the turbocharger or the lmm. has another idea, before I let the parts change now gradually for expensive money. komis It’s always just a mistake, but unfortunately we can’t tell you what kind of building??!! gruss aus hessen
