My silver RS2 Project

Dave these clips you have had made, where do they live please? My flap that should lift when you open the sunroof doesn’t anymore as clips are broken at the top

I managed to damage almost all my plastic trim when removing and refitting over the years, well done on a great job

They sit at the bottom of the lever which pushes the flap down when you move the roof forwards. See the parts diagram on previous page.

Nice show. Unfortunately I was the only Audi there. A few nice Porsche cars and a couple of lovely mk1 Caddies.







I haven't used the car for a month and on the way to the show I got violent boost cut. Cry.
So when home broke out vcds



Looks like I'm going to have to break out the smoke machine and check for leaks. These cars!

dave not sure if I’m missing more than I realised, your prints - do they just clip in?

[Tractor Dave]

Yes, they just press onto the metal tab thats welded to the sunroof and the lever dowel clips into the round part of the clip.

When mine was throwing 561 it was the fuel pressure regulator. Worth testing what it's doing.

Thanks for the tip.
Did a boost leak test. Nothing major at all. Tiny weep from the n75 which I nipped up.



I had an ABY fpr spare so swapped it over.


Still the same.
Tried swapping out the coils. Made no difference. Swapped the MAF. No difference. Cleaned the MAF pins. Still no good.
Read the codes again.


Have I got a faulty oxygen sensor? It's brand new. Humm

Aby is different.

RS2 one is 0.2 bar lower. Are both of yours the same part number?

Hi, yes. Aware of that. I have a new 3.8bar on order. Was just trying another I knew was working. I didn't think it would make much difference. I will test again when the proper one is fitted. Thanks for advice. Always learning with these cars.

[GT500]

I think mine was at 4.1 on tick over. Not much higher but enough to upset it. It did take a few hundred miles to get to no codes after the new reg.

[Tractor Dave]

Ok, thats useful to know. I fitted the new one which arrived this morning. I took her for a drive and I'm still getting boost cut. So might be the maf pins.

[Tractor Dave]

Ok. A small update. I was reading up on this fault code at S2 Central. I think I have eliminated boost leaks, vac leaks and ignition system. So this is fuel related. Either delivery or monitoring (MAF or oxygen sensor).
So I thought I would check fuel delivery.
I have a copy of the RS2 manual and this is what I should be seeing at the fuel rail.


So I disconnected the feed pipe and ran it into 1 litre bottle. I then jumped the fuel pump relay for 15 seconds.
I got approximately 400ml. That's not good.
So I did a little digging and found this!


This is the connector for the fuel pump. Just about hanging in there!
So, whilst fixing this I decided it was a good time to do the relay modification. Not difficult. I've done this on all my previous projects and it was on my jobs list.
An old vac pipe helps running wires in awkward places.


I've included an extra fuse on the live connection.


Avant fuel pump and sender wires run through here under the back seats.


A mess.


And after some Tessa tape and a tidy up.



I need to make a mount for the relay which is temporarily wrapped in some foam.
I've tested everything and car runs and fuel gauge works.
Road test tomorrow. Fingers crossed this has fixed the issue.

One thing i forgot to mention is that doing this mod makes it really easy to fit a hidden immobiliser. Just a simple switch in the trigger wire or battery feed is all you need
