Welcome to the Forum ;-)

I would go over the turbo and intercooler hoses again, looking for loose clips or hidden splits that open under pressure.

If you paid a garage to do the work take it back and tell them to fix the problem. Sounds like they didnt do the job properly.

Hi just wanted to ask has this issue been resolved??

as same thing happened to my 1.6 tdci after new turbo put on at accelation a whizzing noise was heard for 6 months (garag told us "Oh that will probably go after a while as its new" this went on until last night, the turbo failed whilst on the A120 seizing the engine and possibly the gearbox as it rolls when in gear. had to have it towed 69miles to our garage that did the turbo work in feb 2010, they are currently going to strip it down and get intouch with the turbo supplier who will probably want it returned to them so they can have a look at it..................so now its a waiting game and hopefully the turbo company will except liability of a falty turbo and cover the cost of the repairs.

if anyone has any information on this sort of thing please comment thankyou :-)

Thanks for that the garage managed to get a bulletin from a friend at fords regarding the turbo with 9 pages of strick instructions on the procedure to follow before fitting the new turbo, I have a copy of this and i'm pretty sure they did there part correctly, the AA guy did show us the turbine which was not sitting correctly his word were if you put your finger in there you should be able to turn it around. in ours your couldn't.......... we have to wait and see what results comes back from the turbo supplier now
