Okay, following on from this thread, I have undertaken the following works and am now running out of options:
1) Have cleaned airmass sensor with brake cleaner
2) Have replaced both boost pressure control valves
3) Have replaced boost pressure control sensor
4) have checked pipes
5) Have checked wastegate regulator which was sticking but was freed with cleaner
Please can anyone tell me what other things to look for...The code is P1470 which is boost pressure related. The turbo works (when the car is not in limp mode!) but sluggish at low revs. It takes 2-3 seconds for the car to pick up and accelerate... but when the turbo kicks in, it is fine....
After approx. 5 mins of driving, limp mode kicks in. It really feels like an air intake problem...
Please help....what is the next step ?
