prharris

hi mine is a petrol 2.0 tsi 147kw. yeah, replaced the relay (646) found behind the thick loom, on mine it is separate to the other relays (it is by itself). as soon as the 15amp blue fuse was out the fuel pump/prime stopped running, essentially the relay I had was fine. I tend to believe there could be another relay associated with the function of the fuel/primer pump besides the one mentioned above. any help appreciated. Cheers.

yeah got checking to do, well, its going to my mechanic, but thanks toot for your help

No, never use to do it, everything else is fine electrical within the car

Hi guys new to the forum fuel pump running whilst car turned off, (is it under the seat?) hear the sound coming from under back seat. battery dead flat because of it! so we pulled the fuel pump relay 646 and replaced it with a new one. (No luck) still going. pulled the fuse to the pump and it stops, so somehow there is an alternate power source or short circuit. Anyone have any ideas! would be greatly appreciated. Paul
