  Hi Guys,

  Many thanks for your suggestions so far. Ok, no jumping off the bridge an=
d the car is grounded pending further investigation, esp. the crankshaft pu=
lley! Whatever, this doesn't seem to be heading far an easy & low-cost fix!

  As a matter of interest, is the crankshaft pulley wheel disturbed for any=
 reason when the cambelt is changed? If so then the belt change was done by=
 my local VW dealer. Otherwise, the problem would be there from the beginni=
ng unless something happened during the first owner's time with the vehicle=
. If when I do the check & find it is loose, could I tighten it up temporar=
ily myself? i.e. at the mid point of the slack when turning the pully one w=
ay & then the other ... hmmnn, sounds a bit ropey, but might prevent the ke=
y from shearing off and causing horrendous damage?

  I'll search for the crankshaft pulley info at Fred's although my similar =
posting there has so far got 20 reads & no reply. Have also just posted to =
vwdiesel at vwfans.com with a synopsis of your responses.

  Looks like I'll have to instigate an emergency re-instatement of my old P=
eugeot 505 petrol (guzzling) estate, after fixing a few items & getting it =
teted.

  bolt in the nose of the crankshaft sufficiently high enough to grip the

  Hi Mike
   Whatever you do Don't jump off the bridge. If anything, push the car
   over but don't jump. It isn't worth it.
