I have been trying to fix a coolant leak at the rear of engine; the flange (2x 10mm hex bolts) of the black metal pipe that runs from the back of then engine on top to the front.
Tried adding silicone RTV, leak. Cleaned and tried black RTV, leak; and now O ring is cut.

The pipe has about 32.5mm (= ca. size of O ring ID)
The hole/flange has about 37.5mm (= ca. size of O ring OD)

I need to find a new O ring.

Does anyone have
- the correct dimensions?
- Official name?
- Part number?
- Source?

Thanks.

Here young padawan learner, let me introduce to you the mystery that is ElekTronischer TeileKatalog (ETKA):
http://www.auto-parts.spb.ru/cat/au/au.mycat?SelPg&t=mjPtNEkz7TQDM_002GmFDatytBLJalXwHyjtNKnsbQSac_/LehfNHpoXzIOaE_2_l3/9Z0kRl6wEoN_32XetNJo/FXISn_Gx/JhvImKMctrAIav4yeEhzltXLQzuArU8lzKAry7649iEPtS0G8G kdlR9rGLyV_d6u/Ly4P2o2X7AmaH6PkiBuz0xbUfh4tj7yhI126mN5HLnCBWPCBov sB/1yRxC

Item #13 shows the following:
Dimensions = 31.5mm x 3.65mm
Official Name = "Sealing Washer" (actually not bad as far as ETKA part names go, lol)
Part Number = 058121687
Source = ETKA would imply a VW or Audi dealer, but HERE (http://www.europaparts.com/coolant-flange-o-ring-058121687.html) works (http://www.ecstuning.com/Search/058_121_687/ES250825/) too (http://www.autohausaz.com/search/product.aspx?sid=kdxqyoe3f1brxs552ck2hs45&partnumber=058121687) (once you have the part number, the world is your oyster)

thanks walkytalky. Is there a (free) way to get that ETKA thing?
Even in Russian (pictures/tables) would be much help.

Would be great for all my Audi/VW cars:
1996 Audi A4
1998 Audi A4
1998 VW Passat
1999 VW Passat
2001 Audi Allroad
2002 Audi Allroad

Wow. I don't know how you have all those cars without ETKA already, lol.

I thought my link was self explanatory as far as ETKA access, but I suppose the Russian links do make the interface a bit difficult to parse on the first go-round. Here is a link to the top level:
http://www.auto-parts.spb.ru/cat/au/au.mycat?SelVh&cl=

You will see most models will have 2 links. "Европа" and "Америка" ("Europe" and "America"). The former is handy for looking up cool Euro parts, a la BEX manifolds and RS4 goodies (obviously you have to know the diagram number you want...or Russian). But for engine parts and such you want to choose "America" so you get the correct engine codes and such. And the navigation is English, so that helps too.
