So slowly I have the impression that my car doesn’t like me anymore 🙁 Just I get into the car on the company premises, engine starts and all lights go off (as always) – only “check engine” burns. So again exited (engine continues running), bonnet up and rough checked….was still available, the engine. What now ? engine runs like it should, on gas and on gasoline, the car drives quite normal, the loader runs, power is available (well, I was a bit ahead of tig, but more than a base charge pressure he already brings). Engine switched off several times and left again – no problem. So what does he want to tell me? I drove home now the 35km (average consumption was ok)… What would you do – to the next Saab workshop (45km) and let me read out errors, or disconnect battery and so delete the error memory ? Does someone have clever suggestions what it could be ? Only observation would be a slightly lower idle – at the estimate I guess about 600 rpm….hm. False air ? hoses all seem to be still there; flashlube container is still full.
