Well been having problems with the LImp mode and EML light coming on and off since i bought the car in FEB so this weekend i decided it was time to strip out the EGR and boost sensor and clean them. Since doing this i cant believe the car its totally different from what i have been driving so much smoother. What i wanted to know is how do people get rounf the back of the valve in the egr as there is still alot of crap in there. The other thing is when i removed the box that hold the boost sensor (sorry dont know what its called) in that was full of carbon do i need to clean that aswell and what will that do? Over all much more happy with the car was getting to the point of nearly selling it.
