i bought a '90 quattro sedan with the small v8(3.6L i beleive), and would like to know what to look for as in terms of preventative maintenance.

I am a military mechanic, but this is my first time dabling in the german passenger cars, so any and all help would be greatly appreciated.

First! Welcome to out little assylum! [sm=alcoholic.gif][sm=outcold.gif][sm=smiley8.gif] We are one happily dysfunctional family!

The V8 is nice automobile and a unique ride that Audi has produced. There some V8 only websites that will probably give you more specific information. Over the years I have seen at least two.

Many of the suspension and interior parts are similar if not the same as the 100/200 models but the power plant is unique to the V8 only. I have not heard of too many common problems with the V8 motor but the suspension you will probably want to rebuild. If the shocks have not been replaced it is a good idea to do so, the original shocks rarely make it over 10 years. The same goes for suspension bushings. The rear calipers sometimes stick, easy and cheap to rebuild except for one seal that Audi doesn’t show on the parts list but easy to use one from the transmission. Another sore spot is the leaking central hydraulic system used for steering and braking.

Good luck!

 

ok, i bout the car, it cranked over, but no start, gettin fuel, fire, comp, have no idea what i am doin, so before i screwk somethin up, i will check here first.

and where can i get good aftermarket componets for this car, cause me and stock don't get along.

 

rare motor indeed only made for 2 years, haven't used these books for years just as well I still have them

The sucky thing about the V8 is its rarity. You are basically at the stealers mercy when it comes to parts and V8 parts are at extra premium. This was one reason why I didn't buy one myself.

The V8 engine management should be better than on 100/200 models so try to pull some codes of off the ECU.

 

Great car if it has never been overheated or had a broke timing belt! Make sure the T-belt did not break, if it did it will be to expensive to fix without used engine! High compression, all aluminum, 32 valve- not an ordeal for a beginning machinist!
Mine has 175K and still runs like a dream!
Make sure the tranny and rear end have proper quantity of fluids. Mine had the rear end rebuilt just before I got it because the spot to check fluid in the rear end is a pain to get to and usually gets ignored. Also replace the fuel pressure regulator, it will develop a leak and some have stripped torque converter plates after the press reg caused fuel to fill up one cylinder or another. There is a small breather hose under the assembly that holds the Idle control motor (IAC at front top of motor). The hose runs UNDER the intake manifold and when it starts leaking vacume, the computer freaks out. Sometimes this will cause the tranny to go into limp home mode (gets stuck in 3rd till you restart the car)
