Got this problem with my 98 20v turbo, when i start it cold the car starts fine as always, runs for 30 secs then i get this loud squealing for about 20 secs, doesnt help if i rev it (thought maybe a wet belt) so all i thought it could be is this secondary pump thingy but i cant find anything in tne maintenanace section.
any ideas or useful links lads?
cheers, pete
