In August 2020, we bought the above-mentioned vehicle. For a few days, two control lamps (gear unit and wrench) have been lit in the cockpit and the message “Check exhaust system” is displayed. In the workshop, we were informed that the message indicates a problem in the exhaust system resulting from the predominantly short-range operation of the vehicle. It was recommended that after the resetting of the fault memory with the vehicle a longer journey on the highway du I am not ready for this procedure, because it can be expected that a new vehicle will be able to operate without interference even in short-distance operation. Is there any experience or solutions to this problem?
