1990 Audi 100 Avant turbo. Op Project Creep

I had a next-gen Audi 100 (the shape that became the first-gen A6) that I got cheap because the ABS light wouldn't go out. That was because the car had been jump-started and blown the ABS fuse. Hard to tell from the video though, are you sure that's an ABS warning? Looks more like either brake lamps or pads warning, but it's quite hard to see.

I've finally managed to sort the overcooling issue. It turned out it was the multi temp sensor. It's quite a complicated sensor with a 12v feed and then 3 outputs. I think one to the gauge, one to the ecu and one has something to do with the a/c I think. Anyway what's been happening is every time I've got it wet while changing a thermostat it's started working for a while and then as it dries up its been failing. So now it's been replaced with its 3 pin (no 12v feed) equivalent, I have rock solid temp display and I seem to be getting better mpg.
I did create one hell of an airlock but that now seems to have shifted itself.

I've also given it a wash and tried some boiled linseed oil on the plastics. It's come up very nicely so I've given it a good coat of wax as well






I've had a thought on wheels and I think some banded Mercedes vito or vw T5 steel wheels should work, maybe either a gunmetal colour or a fairly subtle dark bronze.

Not looking so great now though after a weeks commute


My car would have been fitted what are known as the "man-hole cover" wheels. Think they're only 15", hard to come by in 5 stud fitment and usually fairly expensive


The ronals I think are also 15/16". I've only ever seen them on the 200, not the 100. Could well be wrong though. These go for mega money when they do come up, which is never.


To me, audis in particular of this era look a bit under-wheeled compared to their competitors

Anyone else mad enough to attempt washing their cars in this weather?
It's been the first weekend without a storm blowing so thought I'd give it a go. I was regretting it deeply about an hour later, curse word wet through. But glad to have actually cleaned the thing for the first time in 3 weeks


I even cleaned and fed the leather


It still feels a bit dry in places. I might try a different product. I've heard horse saddle treatment is good stuff

Some of the tatt has also been removed. Non functioning high level led brake light scotch-blocked into the loom was particularly offensive and the last of the stupid German style plates has gone





Much less embarrassing

I love those wheels on it, they are perfect. Look expensive and classy and not too "scene", which banded steels might do. Probably would need lowering a fair bit for steels to work anyway looks wise??

Those Porsche wheels would look good.

Oh yes!!!

The Audi has been putting in a lot of work recently

As well as doing a 40 mile round trip every day to work its been lugging cement and sand and doing all the shopping

The owner that lowered it disabled the self levelling suspension purely because the self levelling dampers were unavailable and the old ones were shot. I could have done with it while carrying over 500kg of sand and cement about.
Extra lows.


To be fair it handled it pretty well.

One thing that has happened is that while driving the removable facia on the radio sprang across the car. The little tags have given up the ghost so it's now dead. A radio has moved up the priorities now and I'd like a period alpine radio cassette. I have my eye on one on ebay.

Other than that it's had a quick wash and hoover as it had become fly-mageddon




It does come up nice, although there's plenty of room for improvement.

I've also done something I've been meaning to do for ages and picked out the turbo letting on the fannymold in red

At the very least that's an extra 10 horse

The cam cover is really letting things down in there now

The CIS system responds very well to injector cleaner in my experience. Both GTIs and both 90s appreciated the occasional dose.

I did replace them on my second 90 (B3, 2.2 KV code) at about 160k and it made a massive difference. I had previously checked their function by yanking them all out and sticking them in jam jars, still connected. If you then bridge the fuel pump relay, so the pump runs and lift the air flap - they squirt - an you can see the spray pattern. Mine were like cheap water pistols. Two of them also dripped when they shouldn't.
