Old thread but just been researching this myself and found this
There has been a good measure of controversy over this question. Here is what our own experience shows. Over the last decade we've had no compatibility problems mixing the CHF 7.1 non-synthetic mineral base fluid and the CHF 11S synthetic based Audi power steering fluid. No problems with our own vehicles and no problems with our customers vehicles. Our success in mixing the 2 Audi power steering fluids coincides with the Audi tech bulletin 48-89-T07 issued in November 1989. It states "The new [synthetic Pentosin 11S] and old power steering fluid [non-synthetic Pentosin 7.1] can be mixed if necessary ... the part number [remains] unchanged." So according to Audi, you can mix the 2 Audi power steering fluids. Even though the composition of the fluid changed (CHF 11S synthetic mineral oil vs CHF 7.1 non-synthetic mineral oil), Audi didn't even change the part number. All 1990 - on Audi models have come filled from the factory with the synthetic CHF 11S Audi power steering fluid (G002000). Please Note: Never mix generic power steering fluid or other fluid with the CHF 7.1 or CHF 11S Audi power steering fluid (G002000). If you or someone else did, flush the Audi power steering fluid as described below.

Yes, good plan but you will have to drill holes for the other side.Leave a comment:

Thanks. The reason I’m interested is that I knew that something like that or a wheel arch liner would contain a lot of the spray and rubbish thrown up from the road in the arch rather than it finding its way into the engine bay. I’m guessing it was on the near side as there’s more sh*te to be thrown up from the kerb side. Both sides, if I’m making them myself, probably won’t do any harm.Leave a comment:

They were only fitted on one side. The original material was a type of rubber sheet.Leave a comment:

Did the car have splash guards fitted originally?I made up a new splash guard from tractor inner tube. Strange there is only one on the nearside on the Ur.


Tie rods were fitted. These failed quality control last week so have been stripped and painted again. There were one or two rust spots coming through.

And then drive shafts. All new cv joints.


And I got this from Rob on the forum. Very impressive copy of the original.

I'm waiting for my new boost hoses which are coming from Germany. I got stung this time with import duty. Cry.
They are in the Swansea Parcel Force depot for the weekend sadly.

I can appreciate what they’re designed to do but have most uRs lost them through time?
What material was originally used for them?Leave a comment:

Do you want to buy another one? I'll sell you mine as long as you sell it back to me once you've restored it

Wow, after all that work I'd want to get at least a summers drive out of itDeposit taken.
I put something up on Facebook Classic Audi yesterday and was inundated with messages!
I've got what I consider to be a sensible amount for her. I've not made any profit or loss. It's going to another enthusiast which is the most important thing in my mind.
Did you take into account all the hours you put in when you say you broke even?Leave a comment:
