Hello together, since yesterday proud owner of an Omega B 2.5 V6 CD, Bj 1998, with LPG drive. During the test drive much on me, that the interior heating only blown Lauwarm. The seller literally pressed a few switches during the ride, also the next to the Automatic switch lever, where there is a snowflake on it. He said that would be an additional traction aid, next to the normal TC help. Have read many pages here forum, because of the lukewarm air. But it may be, because the dealer has turned on the air conditioner instead of a traction aid and thus only lukewarm air comes out. I can not test it at the moment, because the vehicle is still due to repairs at the dealer. my next step would have been if I had the vehicle to open the said back door “explained by KurtiBerlin” and to flush the heat exchanger Furthermore, the lambda probe failed according to error memory, even a new one could not fix the error. r opel dealer already had to move it to tomorrow boys and girls hit the keys to give me a few tips in advance
