Hello together, after coming again from the friendly just I’m desperate. I just bought the car with real 22,000km on the Tacho. It was a second car, and garage vehicle. Top condition. Before the purchase I let the car from the DEKRA cheken, astreine exhaust values, no error message in the display. Then proudly drove with “new” old S80 300km home, immediately into the washing garage and then came the error message Emission: Maintenance required. I would say that the car pulls normal, no engine rucksacks, no nix. Did the error message now delete various times, but after almost 20km the error message comes back again, if I miss the engine and then start the ignition and then the display remains permanent. The LMM has already been exchanged, errors nevertheless came again. What can that still be? Drosselklappe? or Lamdasonden? I would be very connected to you if you still have the one or other tip, as I can quickly analyze the error (best with instruction) to invest the new parts without being defective.
