Squeeling belt??
The Penny Trick:
  1. remove belt
  2. back of the single stud holding in the tensioner
  3. put a penny in the 9 o'clock position
  4. tighten back up, put belt back on.

Hi all. 1994 M Reg. 300 TDi.
I changed my Timing Belt and Serpentine Belt yesterday. Squeeling started about 2 minutes into test drive. I will do the penny trick tonight when I get home 'cos I believe wot you say.
But can anyone explain exactly what is squeeling (its like a budgie wanting feeding!) and how the penny trick actually stops the squeeling? Is it 'cos the new belt is tighter than the old one? Does this indicate a problem with the tensioner or its design ? (Just curious).

Thanks Gals and Guys.
 
the tensioner roller is acutually 'out of true' the penny brings it back in line Its a manufacturing fault on these engines. Replace the bearing £5 off ebay. instructions are in this forum.
 
Just done the penny trick, That noise has been driving me mad for weeks. iIfitted a new belt and bearing, still it came back. Not anymore. Thanks.

All you guys should be paying £1 each to Battenberg!
He'll be a rich man if all the 300tdi owners using this idea send him a pound!
I'm on 25% commission.

You're a legend!
I seriously couldn't work out what the noise was... I'll try it out tomorrow, because it's one bastard of a noise it makes.

Cheers
Todd
