Hello, I would like to hear your opinion about a diagnosis of my workshop. A Blubbernder Krummer led me to Opel. It was replaced (dried and bolts torn down). The entire exhaust system was replaced (old and extinguished). As far as so good. After a month of Krummer Blubbert again. Back to the workshop. Again Krummer and Bolt New (on guarantee ). After error reading was seen, throttle flap potentiometer, camshaft sensor, crankshaft sensor. Opel: this is our Problem, due to the defects throttle flap pot. is burned wrongly and the cracker too hot. Therefore delay and bolts off. Error Check according to plan approx.. 3 hours. Everything clear ? After a long time call from Opel: After verification new finding: It comes out of the cable on the large plug of the main control unit, thereby impurity on the plug and error message. Potentiometers and sensors themselves, are Ok. There must be two cable sets renewed, 1.700 € and 700€ plus wages, Total €3,500.
