Hello, before I come to you with a request, I would like to say briefly that I am based here in the Golf Forum. My questions refer to my wife’s car. This is a C 30, 125 hp, year 2007, MKB AFU, mileage approx. 65000 KM. And now the problem. The C 30 is hardly noticeable in the 4th or 5th gear, with the slight gas giving on flat track. I once Googled through and the few what I found, allegedly pointed to a dirty throttle flap or poti, as well as to defective/s ignition coils. My questions to you, are these hints realistic and if, what can be done about it? In addition, it would be important to know which mileage performance the ignition coils should be changed/must be. Unfortunately, the inspection checkbook was no longer available when buying the car (worship car). The Volvo representative here always promised to provide a replacement, but what has not happened until today. I would be grateful for every meaningful answer!!!
