Good day. I have an Audi 80 B4 2.0E 85 kw with the following problem. If the engine (ABK) is warm, it starts to jerk. This jerking is especially noticeable in the first three gears and low drez numbers and only when the engine has run hot. I have read many topics here in the forum and then had the exhaust gas values measured in a workshop. The CO emissions behind the cat were 17% (normally 0.3-1). the engine gets too much fuel. Due to various topics here in the forum I became aware of the thermosensor, which I exchanged today. This happened in a workshop and the car was then tested again at a measuring station. The CO values were now at 2% but still above the standard values. In idle mode the car threatened to jump out because the speed was constantly fluctuating. So the engine ran very restless and jerked still slightly. n, but unfortunately there is a risk of damaging the engine if it still gets irregular fuel. Consequently, it could be concluded that a component is still defective. I could not be helped further in the workshop and so I decided to choose other workshops. After several disappointments that I could not be helped further, I decided to visit an Audi workshop which could not help me, but suggested that I keep the car there and that I could not use it. The lack is the price. The workshop would like to have 70 euros per hour for troubleshooting and depending on the error it will be fixed directly. Unfortunately, I lack financial resources because I just bought the car and I am still a student and I have to finance the car myself. Since I noticed that many problems could be helped, I hope someone can help me here in the forum.
