Help me, please!
 

I Need help!
I have a 1990 Audi 90 4 door coupe I believe.
I'm looking to replace the vacuum lines. If anyone has any manuals for that, hook me up !!???

See if this attachment is helpful? It is for a V6..

Well if it's a four door it's not a CQ(coupe quattro) Probably a 90 20v? You shouldn't need a manual to replace the vacuum lines there is a diagram on the underside of the hood. Some of the lines and fittings are specific to the engine and may be NLA. If replacing just the smaller lines I recommend BMW silicone vacuum hose.
