Part No for Main Rear Seal on Gearbox (Quattro)


Registered User
Hey Guys

Quick one.
Ill be doing my clutch on Saturday and last time when I was fitting my exhaust I noticed some leakage from where the prop shaft exits the tranny.

Can someone confirm if this is the correct part / number i need for the seal. b 02x 409 400 a
Are there any other seals etc. that would be good idea to change whilst I have the trans out?

its a 2004 1.8T Quattro Manual.

Also what would be the best oil to use for the tranny, OEM or Aftermarket and does the rear diff use the same oil.

Thanks in advance

Hey, to be honest I never actually got around to it. I cleaned up around the rear of the gearbox and it doesn't seem to be leaking. I'm not sure if it even was leaking to begin with. It could have just been some other fluid spilt on to it.

Sorry I couldn't be of any more help.
