Need help
Hi I am having some problems with my 2003 v40 diesel 115 bhp d4192t3 115,000miles.
I have a wooshing escaping air sound when changing gear almost like I have a dump valve and a hesitant boost (on off on off surging) around 2000 revs so it would almost appear I have a leak in the charge air hose's but have checked all of these and cant find any leaks there.
Last year I cleaned the egr valve, New charge air hose from the turbo, oil change (Castrol edge part synth), diesel filter, KN Panel filter, Oil Filter & Cabin filter, Top strut mounts, Alternator and belt, New coolant, New brake fluid plus more and I still have things to do.
Are the egr valve's meant to come apart as like others here mine didn't but should it to be cleaned properly how do you check the opperation?
What should I use as a gasket for the egr valve apart from the metal one?
The turbo boost valve is it also called N75 valve? Can it be checked/cleaned?
The wastegate on my turbo is rusty?
Pressure sensor can this be cleaned? could this be my problem?
I know I have alot of questions I do need saving Im in Redhill Surrey if anyone close that could have a look or give me some good pointers Thanks in advance Tim
