Yesterday evening, the exhaust control light suddenly went on while driving.Have the fault memory read out.Lambdaprobe 1 current error.Error was deleted and did not come back so far.Kfzler said it was advisable to change the lambdaprobe.But he was not sure if it was really due to the probe itself.At least the cables are not eaten.I should wait for the error to come back.What do you think?
