Hi, I've been chatting to tomomontana about my 1990 300 TT.

It's his opinion and now mine, that I may have a boost leak somewhere in the system..

I've been trying to locate a good diagram showing the complete system and locations of hoses so I can check them for leaks one by one until I find them all if they actually are there.

Does anyone have such a diagram or have any idea of the best places to check first, ie the most likely candidates to split or become loose?

I'm still very afraid of what's under the bonnet of these cars, dark forces are at work under here with many gremlins ready to drag unsuspecting owners in never to be seen again..

Well ok, maybe not as bad as that but it's so tight under there it took me 45 minutes to get the headlight bulb back in this morning! Definitely a positive if ur hands are more the first of chipolata than the premium pork bangers I currently own..

Anyway, guys if there's any info available I'm certain you'll know where to find it. I appreciate your helpful contributions..

Cheers..

few variations but this is the best diagram for the vac system :
