Hi @ all.. First of all: I found nothing about THIS problem while searching 🙁 (in the complete Mercedes Forum) So: a friend of mine drives a C-Class. Car now has to go to the B Check, according to Assyst. But the friend says that the computer only jumped about 200 km from A to B!!! CAN YOU BE THAT? When error reading there were no findings at DC. Say, everything should be OK… MfG and many thanks for your answers Kai
