Hello, I am driving the 4th Omega (A and B) and last year I bought an Omega b Facelift, Bj 2001 with 65,000 KM (renter car with new TÜV). Kilometer level now 75,000 Km, 2.2l ,automatic, petroler. After the purchase all liquids and pay belts changed. So far I had no problems. 5 weeks ago I had start problems and the maintenance lamp went on for the first time. With Tech2 I read the error: throttle valve value implausible! After that until yesterday no Then, however, in the middle of the city, the engine went off idle. Restart only with an increased number of 1500 U and no gas acceptance. I then pulled the plug off the throttle flap and plugged it up again. After that the engine ran again flawlessly. Error memory was again “rossel valve value implausible”. After that no more interference. It is also no longer possible to detect a docking. The car drives 0W40 oil from the beginning. Does anyone have an idea what is going wrong here? Nikolaus
