Not the Surf but does anybody know about turbo's ?

[an1mal_69]

usually when your turbo goes, you loose boost not overboost, so as everyone says, id look elsewhere.

saying that, your actuator (the bit that works your wastegate) normally becomes weak over time (again resulting in loss of boost) not stronger.

from what you've said, sounds like a boost control issue to me, not too sure how this functions on the diesel, but id presume you have a MAP sensor which tells the ECU what pressure the engine is receiving, check the wires and pipe work there..

I'd like to think that it's probably fixed after over a year....

variable vanes turbos got nasty habbit of clogging up with crap,causing the vanes to stick,if you take to anyone who knows what their doing your prob find they will take downpipe of and spray the exposed vanes with a cleanin chemical freeing up the vanes.job done .vw suffer with it vanes work well when working but clog up really easy

Thanks for your concern guys but it was fixed around a year ago ....

The turbo guy recommended that I give it a good thrashing once a month - I'm doing 25k a year so I thrash it weekly and the fuel consumption is actually BETTER than it was before the turbo went !
