scotthollings Posted September 21, 2014 Posted September 21, 2014 Hello was wondering if anyone could please give me some advice I recently bought a c4 vts 2.0 hdi model 2005 when I bought it the turbo was not working so managed to quickly diagnose turbo vacuum solenoid at fault which I have replaced and now have turbo but have now been left with another fault where if you put your foot down it hesitates then surges a couple of times and it does this through all the gears, I suspected the egr so went to fit a blanking plate today but found out someone had already fitted one should I still suspect the egr with plate fitted or rule it out. Air filter and fuel filter have also been replaced. Oh and there are no warning lamps on or fault codes in the system. Any help would be much appreciated,thankyou. Quote
paul.h Posted September 29, 2014 Posted September 29, 2014 Welcome to the forum. It may be worth looking for any air leaks in the ducting or hoses and check for splits at the ends. Maybe also check for any restriction in the air supply ducting that may be causing the turbo to overboost and cut back. Quote
