My S2 coupe bit of a rebuild and repair thread.

[Nuvo]

Nyuk, nyuk, nyuk.

My S2 has been dry as a bone for the past 3 years....It's on axle stands in the garage. Problem sorted

[newsh]

The frameless door doesn’t help matters but it’s not too hard to sort.
The worst problems have been from the sunroof drip tray migrating south.

[B5NUT]

I got one of these to cover the car, as I knew that water was getting in but figured it was the sunroof. The cover is not cheap, but it's kept the car dry and even with the current storms it's stayed in place and I cannot see any damage to the paint work. However I am going to get an indoor cover to place over it then put the outdoor cover over that. just to keep any rubbing to a minimum.

A trick of the Audi gods

[B5NUT]

Been looking closely for accident damage and cannot see any when I removed all the interior trims there was no sign of any repairs. I really am surprised by how many water ingress issues that this car has. With it being a 3 door I would have expected fewer problems not more.

[Bowie69]

P.s. they are a pain, but worth it when they are finally dry.

Also worth considering, a car port or garage to keep them in

[Bowie69]

Think I need to do mine again, will tackle when resprayed (something I know I have been talking about for about 5 years!)

Also check for rear accident damage, and leaks through badly seam-sealed seams.... especially under the aforementioned black trim in the corners.

[B5NUT]

You guy's are not filling me with confidence here! Feel's like a purchased an S2 colander

If all else fails I'll stick a few holes in the floor

The other place for leaks not mentioned in those threads is under the coupe hatch bottom seal; it's an Audi design feature and as the water goes on to get inside the rear of the light clusters, the light cluster sealing gets blamed - wrongly.

The substantial black plastic trim piece that runs across the bottom of the hatch opening is fixed with 4 M6 bolts. The holes for the bolt threads go through the bodywork and water runs down past the threads. The outer two bolts are above the rear light clusters so water drips off them directly into the back of the rear light cluster nicely corroding the light cluster connections and making you think the light cluster sealing has failed. Refit the bolts with the threads well sealed with sealant.

I’m surprised that isn’t in the list at the beginning on the “definitive coupe leak” thread!
I screwed those back in with a ring of dumdum underneath and had no problems since.

The boot lid and seal design on the coupe is rubbish. You can adjust it so it needs a good push down to close it. Still doesn't seam to prevent leaks though

Yep, had to do that with mine as well. Even then it can still leak depending what angle the car is parked at. And then there's the noise, my NG Coupe nearly drove me crazy, sounded like a Chipmunk orgy was going on in the boot, even Tiff from Topgear commented on this when he test the first B3 in 1988. Had the same squeaks with my S2 though fitting a straight through 3" system pretty much fixed it on that car.

Thanks will add that to the growing list of area's to check. I'll do the hose test tomorrow as the car is just about stripped from the boot all the way to the dash, so should be able to see any water getting in. One thing I have noticed on the boot is there is slight play on the boot as if the boot catch is not holding it securely to the seal, or the seal has failed and that's causing movement. I would say I'm getting about 1-2mm up and down movement on the lid.

That's very well remembered, I knew there was another one at the back that I'd had to contend with, was racking my brain about this as well! Forgot I did this job on my NG Coupe not my 3B and it fixed the leak into the boot. Perfect write up there johne.

To be fair my brain has been busy today with various extra matters. Yet more fire wood, I measured my heating oil with a dip stick as I didn't believe what the Watchman gauge was telling me (ie I'd used hardly any all winter) to discover I'm very low, good luck getting a quick delivery at the moment! And helping someone with things over on Classic-audi which has cheered me up.
