Hello together, the following problem / the following question: My V70 1 (year of construction 99. 205000 km) has been running in gas operation for some time and the engine control light is also on. The car goes off when switching down, or has rotational fluctuations… In the workshop I was told that the lamda probe was defective. 1. Question: In petrol operation I did not have these problems ? Shouldn’t there be similar problems in benzinbetrieb?? The good master has fitted me a new one, which however did not bring any improvement.. He said to me that he possibly got a wrong one and has to get another one in there… What do you think about it? what can I do ?? Greeting
