It's had a new governor valve, a new intercooler (split) and a new control valve. Still going into limp home mode on a very regular basis. Codes are inabillity to control boost pressure and both low and high fuel pressure warnings. Local garage have recommended the turbo coming off and being worked, lubricated as the vanes can stick. Now we certainly have to try something but a new twist has lept into the mix. I always thought that the KEY cause was wide open throttle openings but increasingly, it seems that it's when the car is going around a bend. I went around a roundabout from dual carriageway to dual carriageway at constant throttle yesterday and it threw limp home as soon as the car hit max horizontal g going round the bend. Revs were at about 1500 so no real boost, no acceleration and the only "force" as such was horizontal. Makes me think of tank pump / pickup being blocked or something.
Any thoughts guys?
