Transmission cooler line O ring at radiator

[m_haiser]

after doing my timing belt and nicking an o ring ive been leaving small spots of trans fluid all over the place. finally got around to fixing it (or so I thought) on sunday
however I get out of my car today after lunch to find ive left a trail, and a small puddle where I parked. so I called the nearest audi dealer (I live 2.5 hours away from them) and they
cant get it to me until Monday. I was smart enough however to get the oem part number since I haven't been able to find it anywhere and plugged it into the carquest(advance auto parts) website
and came up with another part number that they can get me tomorrow morning. all this sob story just so I can share the part numbers I found so that hopefully nobody else has to go through this same ordeal.

OEM part number as I was told is N90666003

the carquest part number however was
J5086395507OES and described as AT COOLER PIPE SEAL.

again, hope this helps someone in the future!

The N... is an audi part # and should be correct. The J5086395507OES is some other manufacturers part number. I can check for you in ETKA which exact part number is that o-ring.

I know the N number was oem but OEM part numbers don't always cross reference well so I gave the other one that is worldpac.
if you could double check that though that would be awesome

Yes, this is the correct one. I had listed it as N90666001 but N90666003 is the same 11.5x3 o-ring probably updated at some point.
