Hello on Friday I bought a Pheaton V6 Diesel BJ 2007 96000km. I got the car from HH everything was top when I refueled after about 150km and so made 30 min break I drove again with a wide grinning further home towards Kassel After about 10 km then the terrifying beep beep and the error ^Abgas workshop^ I then carefully drove to home. Next day I drove to a free workshop and let the error read. There was somehow dDross I couldn’t read exactly as the car master had already deleted the error. I drove away after that. About 10 km the error came again. Can someone help me and give me types what is defective. Thanks in advance. LG Kadir
