My car has been increasingly getting worse over a period of 2 years with this problem. When driving the car acts sluggish when trying to accelerate slowly. It also happens when i keep a certain speed and then release the throttle a split second, and when i accelerate back. It feels like the car loosees power for just a half second before it starts reacting to my foot on the pedal. So that basically means that whenever i try accelerate, first the car "loose power" for a split second and the car slows down to the degree that everyone in the car thinks u stopped pushing the pedal, before the car starts to accelerate at all.
After using a diagnostic tool on the car, i found that one of the codes were for the EGR valve, and some other ones that were unspecific. The entire EGR-valve was cleaned out together with connecting exhaust pipes. This was probably 40% full of black stuff, sadly it didn't resolve the issue. I have a new dynamo as well, as one of the other codes communicated some voltage problem. Both of these codes are now gone, but the car still suffers from the same problem. I've seen a number of posts about similar problems with this car, and usually the answer everyone gets is the EGR-valve. That didn't help this car unfortunately. Would updating the software on the car be a soultion to this problem? Is there som sort of electronic throttle unit that can be replaced? Or is there some other mechanical issue that can be the root of the problem? I should mention that the yellow engine light comes and goes in periods depending on how long i drive. When i drive on the highway, and use the cruise control the car doesn't manifest this problem at all. But when driving in the city and suburbs at a slower speed, not using cruise control, the problem is present and continuous.
