Again a small new problem. After starting the MKL is lit up for 1-2 seconds. Then disappeared again and no longer appears. About OBD we read out the following:P0130 Missing ??? (8) Lambda probe signal not correct As far as clear, something with the Lambda probe seems faulty. The hint “P0130 Missing ????” is not clear to us. We have therefore deleted the error and it is not stored again. Anyway not so far. Likewise, flow through the ventilation system. g since a few days, always after starting, a swing gasoline and exhaust fumes. Reinforced at the first daily cold start. In the driving operation then “pure” air is to be determined. What should we look for now? We have the garage available including tomorrow and could go on troubleshooting.
