Hello guys, I need your advice. I’m driving an Audi A6/C4 with the 2.8L AAH engine. The car makes me worry about idling stability/controlling. I’ve been off the car for 2 years now. Since that time he has problems with idling stability. About 2 weeks ago I was with the car at the TÜV and had to have AU done. There was nothing complained about. I had even pointed out the joyous TÜVer to my problem. However, you have nothing to do with the exhaust gas values. The car was already in 2 “specialist workshops”, but they did not find anything…. One of the garages tapped on dirty throttle flaps. Therefore, he cleaned these… whereby he admitted that the throttle flaps were quite clean. Unfortunately, it is so that it happens again and again that the engine dies if you want to turn or stop at the traffic light or at the stop sign. I allowed myself to upload a video on Youtube. The video is under the link:https://www w.youtube.com/watch?v=Da0m-1r5_ho&feature=youtu.be. Many times you can watch/hear the video. I started the car in the video with a cold motor. At 00:17 the secondary air punpe turns on. At 01:40 the secondary air pump is switched off again. At 03:05 the speed is reduced by the first stage. The speed crashes and then catches again. At 04:20 the speed is reduced by the 2 step. It snaps again DEUTSCHLY and catches itself At 05:55, 07:30 and 09:20 the speed is reduced by further steps, as the engine is getting warmer. Nqach another 5-6 min would simply die off, as the engine will no longer catch itself after the speed reduction…. In addition, the speed will always fluctuate after my ear…. Do you have any idea what can be…? False/side air, ignition or lamda probes? Can you help me? Greetings
