Thanks, I hope I’ve done it right tho as the info is a bit sketchy on how much fluid to put in, this was the coupling off my spare diff and switched it for the coupling on the car, I plan to do the same to this coupling so if this one seems ok I’ll just repeat the process. I still ain’t got 4wd in reverse tho, I’ve purchased a new switch from vw heritage but still not engaging the lock solenoid. The only thing left is the relay but ain’t checked that yet. Do you know if there is a fuse for the solenoid?
I’m confused now, I thought the reason the switch on the gearbox has so many contacts is for the 4wd in reverse?? It’s supposed to clunk and lock the diff when put in reverse?? Or am I reading things wrong?
Can anyone tell me does everything look normal in my fusebox? I’ve noticed there is a jumper wire joining two pins in the gap between relay 53 and 80, is this supposed to be there or has someone just bridged the two contacts for some reason?
