Title: 2001 tdi 90 turbo problem
Post by: luke23 on 22 July 2009, 03:45

alright
im new to this website and have had a read through some posts about the turbo promlems

every so often when accalerating (sp) the turbo goes off then if i turn the car off it comes back on.

then tonight i got in the car and after about 2000 revs its making a normal whistle noise followed by a noise that sounds like a police siren

its quite loud aswell. its been blowing out a bit of black smoke but then i expect that with a diesel

does anyone have any ideas where to start looking
cheers

stick your head under the bonnet and start looking for loose / disconnected hoses as a starting point  :smiley:

i couldnt see anything wrong, the noise seemed less today and a bit more power back in the car?

Sounds like a boost leak, jack the car up and look at the intercooler pipes, make sure they're nice and tight with no oil around them

my dad more than likely thinks its the pipe going to the intercooler.
he is popping it to his mates garage tomorrow for a check over.

Mines making a whistling noise too  :sad: I only noticed it when letting off the accelerator last night.
The more rev's when letting off the GO peddle the louder the whistle, that's about right though isn't it for a boost leak?

Yesterday I had the sticky vanes problem, put some Redex in and booted it a bit not had it again, hopefully won't have it again.

I'll have a look for loose pipes later.
