[adam101]

HI ALL

Every time i put my foot down i get a sound like air escaping ihave checked a lot of the pipes they all seem to be ok.

How do i remove the tray under the engine think im going to have to buy some sort of car jacks so i can get underneath.

I would like to thank you all i did not have a clue about cars but thanks to this web site iv been soldering wires changing oils and brakes.

So thanks in advance  2001 tdi auto 115

Check turbo outlet pipe, there's a short rubber elbow pipe just before joining the metal tube, (drivers side) will be revealed once the under tray is removed, also check the intercooler under the main radiator.

Cheers for that but how do i remove the tray

[chrispb123456]

You will need to jack up the car or put it on ramps owing to the depth of the tray.

There are for bolts, two each side and two nuts at the rear.

I this noise just started suddenly? or is the car new to you? maybe noise is normal spooling noise from the turbo, is there any loss of power? if there isn't wouldn't be to concerned.

[adam101]

No have had the car for 30 000 miles yes the noise has just started and its losing power going up hill

and its starting to sound like a tractor

any ideas

cheers mate

You could have a small split in a hose which could be hard to see, check all air charge pipes carefully, loss of air charge pressure would be confirmed with an underboost code stored on the system.

Fixed

After hours of taking pipes off cleaning bits  cutting my hands to shreads

found a  hole in a metal pipe at the back of the engine half way up really difficult

to get at  chucked some gum stuff in wrapped a bandage round it bingo fixed

Thanks to everybody for advice must have saved a few quid so untill next time

Thanks again
