No Boost on S4 !

[Olly__K]

well, i guess the honeymoon period is over now.......put my foot down last night and could only muster up about 3psi of boost ! car felt horrible !
So I'm guessing there's a leak.......i've got some forge DV's and a samco TBB coming......haven't had a chance to investigate yet but do you think I've got it covered with those parts ?

Could be an actuator getting stuck, and not opening the wast gate properly.
Like you said fit all the parts and then see where your at.
Take some pics if possible, should look good.
What colour samco hoses?

i wanted purple.....but they didnt have it in stock. got black instead !

VAG-COM.

update : change DV's and TBB, old ones looked good, so needless to say my 3psi of boost still remains. AmD on the phone tomorrow then /ubbthreads/images/graemlins/frown.gif

I can advise you what they will say.
" If you can get the car to us we will take a look for you, it could be such and such but we would have a better if we could look at it "

Take your car to a good tuning place and ask them if they could check the pressure on your actuators that will cost you about a tenner.
If they are sticking then = no boost I had this problem on an old RST that i had.

thanks mate, I know they are going to have to have a look, I hope it is that as the turbo's dont sound bust !
Also, there was some Oil in the TBB.........normal ?
