A few months ago I read out the illuminated Check Engine lamp from the ADAC and had it deleted. The error message was somehow as precise as the Oracle of Delphi. Then I had some rest. Until about 6 weeks ago. To the Saab-Opel nearby. Also let read out, similar precise error message from Kat to anything else. Since shortly afterwards the 150000 km inspection, wanted/should be looked after. Of course nothing found. In the meantime the 7 years old battery has to give up the mind. New battery bought. If that somehow has to do with this lamp. Just for the info. For a few days this stupid part lights up again! Machine runs smoothly. Consider if I should stick this lamp off, so that it doesn’t always remind me that there is something that shouldn’t be. Mine, that the forge actually somehow, if something serious, should have found that during the inspection. Or I’m a bit helpless. delete memory and wait for tea or what? Greetings on all sides Wolf
