Good morning, in advance: Yes I used the search function but, ( everyone has found a but ) nothing that somehow fits. Two three months ago the omi in the workshop everything was nice. After ( a few weeks later ) an occasional ruckelei went off. But 3,000 tours on the highway when accelerating went on the MKL and the omi jerked. In the workshop at the tester 20 € all possible errors in total 7. Exterminated again driven then stood firm exhaust gas return valve. G the MKL was there for a short time. So back to Lot, uh, in the workshop 20€ camshaft sensor. The control unit is also immediately displayed as defective, but we only change the camshaft sensor. And look, the same thing. only the MKL doesn’t go on during the ride. But the MKL sometimes goes on when starting, l The next time you start, everything is nice again, except for the jerk. If the 18-year-old son (digital gas foot 0 or 1 ) drives it more than when the father drives the speeding the gas slowly pushes through according to the acceleration. I know to speak to the 2.2 16V Omega with almost 2t of acceleration is something seltam but you know what I mean…. 😉 I have read here about spark plugs, since I will do it today. Nevertheless, I would be interested in your opinion. Thank you. Ps. I am also thinking about buying an OBD. If someone bought something in the last time which also works with the 99er 2.2 let me know. In the bay there are many, but there is often only error read. you can then probably not put it back at all. You a nice WE and my Omi good improvement…( I like it so much…. )
