P38A Heater O Rings

Take the top of the dash off, and put an Audi heater matrix in... problem solved

If it's not sealing up properly, then it could be you have the same issue as I did, where the mating face in the plastic on the heater core itself has a small crack or chip in it, which is allowing it to leak out still.

Hi Marty - Im more familiar with Audis than the p38 Ive now got ...
Is there any particular model Audi to remove heater core from and what accessories - pipes etc do you reccommend taking too?
If you would
Many thanks
Mike

Easier to just replace the O rings unless the matrix leaks.

True dat. I think a new heater matrix is only for when your HAD ENOUGH of leaking O rings. It's two days to get it all apart and back together again I think. Mine hasn't leaked since, but my matrix was weaping along the bottom edge so no amount of replacement O rings would have cured that!

I'd have to look up the date, but my replacement O rings have lasted at least 12 years so far. That's jinxed it
