Hello together, I need help from the diesel specialists here in the forum this morning I started my Omega 2.5TD quite normal, after 20KM work trip without any problems I parked the vehicle. After 2 hours I wanted to drive away with the Omega. I started it, and heard that he was motor nailing (crack-crack clack, etc.) I parked the engine and started again, still the same nailing with huge size black smoke cloud from the exhaust. I had him to tow to FOH The workshop had built a new ESD, and the Nagelt still. Now the master says that it might be due to the ESP or the ECU. Maybe one of you has an idea why the engine nailed For ideas I would be very grateful Greeting Norbert
