In these cars you are suppose to drop the lower part of the air filter housing, not take the top off like most cars. It says to do this in the instruction manual. Also, you don’t want to drive with the diff locked unless you are driving off road. These are the best cars, so technologically advanced for their time. It’s a shame there aren’t more of them around.
I owned an '84 Audi 4000 Q, think it was 15 yo with 160k, 2.2 I5 120hp 5 sp, drove for 5 years 20k miles. Drove like a champ in Minnesota winters. Problem with dash lights, heated seat, and heater - fixed with cardboard in front of radiator.
The center diff locked does affect the vehicle, the front and rear tires make a different distance around corners, and if you leave it locked, you will create unwanted stress to the drivetrain, which can cause the weakest point to fail
Evan Shea That’s definitely true and I have noticed that since. I actually drove it for quite a while with the center locked, you can tell you’re straining it more on pavement. Especially when turning sharp. But I’ve stopped doing it since and only lock it on loose surfaces.
Great vid man! I just picked one of these up for $700 to do a Sport quattro build (Yes I'm fusing 3 Audi's together with a turbo 7k) My Coupe GT roller was $100. Still a ways off financially so it will be fun just to work on the 4Kq without being pretentious. Not going to cut it up until I have more pieces to the puzzle really sorted. Where did you get all your bushing and suspension parts from? Such a cool car!
Hey don’t know if you’re still looking but a lot of my bushings came from 034, and a company called verkline. Suspension came from giant killer racing!
I miss my 84 4000s Quattro 5 manual. I do not miss the shitty heat on cold Michigan days though. My diff lock never worked. I tried to fix it a few times but I was 19 years old with limited tools. Wait till you hit your brakes one day and the reverse lights come on instead and then that little panel that hilds the bulbs starts to melt. Lol.
