Hello all, finally got a 1990 audi CQ, the right one came up and I jumped on it. body and paint is a little rough, will work through all that in due time. Current status is redoing every suspension and steering bushing, struts and mounts, and engine mounts. Car has around 225000 miles so its all tired. Im also redoing my interior. Its remarkably clean and seats are tear free. the door card inserts are falling off so took care of that in my own way. Will be documenting all my progress.

Starting with the interior while I strip my totaled URS4 donor. I redid my door cards in true alcantara suede, with my own take on the RS7 hexagon stitching. I took the more difficult pattern and connected all the hexagons instead of running two stiches simply close together. Its MUCH MUCH more time consuming and a lot of knot tying but I think it looks better. Eventually I plan to do carbon trim, or paint existing piano black, don't care for the wood much.

Tried a different look for the dash piece, and I don't care for it, will be redoing it.

Then I got the AAN and trans out of the UR, to start I will be using the 01A from the coupe, till I have an issue. The plan is to rebuild and use the 7A and 5 speed 01E in my sport Quattro build down the road. Got the engine trans out and tore down the engine as it had questionable compression numbers. 120 120 105 85 and 70. I figured I had a tired engine coupled with the classic cracks around the plugs. Got the engine off and to my surprise the head is immaculate, no cracks. Number 5 hole appears to have one crack, but its only how it looks, no cracks at all.

Number 5 is oily, but the bores are pretty polished up, less and less hints of x-hatch as you go down the line. I will hone and re-ring/bearing the engine and ARP studs for the head. Fairly modest build, gonna do stock management with 04 chipset for GT3071R. try too keep it reliable and plenty of pep.

Any recommendations on rings and bearings>

Also did aluminum subframe mounts front and rear. All tightened up it seems to accentuate slop on my rear diff. or possibly severely worn driveshaft cv's. Already replaced the center support. working on that next. Want it to be all tightened up before I do the engine swap.

Gorgeous interior choice! What is the satin paint you're rocking? do I dare say I see pearl?! Looks great!

Thanks, no lol its just sun checked pearl :( I would polish her up but the clear has come off down to the base coat in a few spots. I work in auto body, so I will be doing a full respray probably next winter, My colors of choice are either vw bambus grey, or nardo grey. I will powder coat some engine pieces to match. And don't mind the hideous wheels. doing a 5-lug swap soon, and have either some urs6 wheels or a4 ultra sport wheels as temporary. I also have some speedlines, but someone rattle canned them gold, and they need redone.

would like to do an S2/Rs2 front and European rear, as well as B4 hood headlamps and grill. Plan Is to tighten up the chassis completely, do the engine swap and hub conversion all this spring/summer, in the meantime start piecing together the hood, grill, lights bumpers and new lower side trims, so next winter I can do the body work and paint. I don't mind the bumpers so much, but they are in rough shape, and do prefer the cleaner look.

Full harness from Urs4 motronic. Just want to keep it mostly stock configuration, and once its all running and bugs worked out, ill step up to the GT3071r and fueling from 034.

Also ive been searching for bulb replacements on the seat heater switches, as well as the diff lock illumination. anyone have any part numbers for original or 12v led options with good fitment?

I should have these home the whole working switches i pulled from mine. I will see if I can get part # or give you all the switches you need but pretty much LEDs will work too.

you have a build thread on your 07K CQ? Im debating running the 07k in my sport Quattro build, or I may build the crap out of my 7A for it.

No, not yet still need to collect a few more parts mostly from Hank.
I thought about it but at the end it comes more expensive to build a 7a than 07K plus the motor is newer for parts availibity.

Hey I looked at the bulb today and mine are burnt too. took it apart and it looks like any 12V (slim enough) will work with a little bit of soldering. make sure you get the polarity right tho. I did the experiment too

Nice work.

Regarding the video and slack. I feel your frustration. That my friend, is likely the rear dif needing gear lash reset. Not exactly any easy DIY, so I've heard. The rear dif on this car is known for being somewhat slopping like that.

I've done just about every suspension/drivetrain upgrade you can on my cq and that slack in the dif drives me nuts. Especially backing up and also throttle off / throttle on situations at speed and high revs.

Some others can chime in, but basically need to open up the dif and add shims to take out that play - or have gears/pinions custom cut.

I've been searching for about a year now for a local rear dif with low miles. Given that it is difficult to find them with low miles period - add expensive to ship across country - makes me think I'll be playing the waiting game for some time. Drivetrain or transmission shop quoted me something (can't remember exact amount) to reset the lash - basically said better off finding a low mile example without as much slop.


Edit/Add: Now I read your comment about inner CV's. I am somewhat skeptical that CVs would allow that much slop like you have there. You can always drop in new ones and see if that helps ($90 a piece for the good GKN ones). I wouldn't bet on it though.
