Fuel Pump Question

[James4287]

I've posted this in the general forum on here but no-one seems to use it sooo i've posted in the RS6 forum in the hope someone here may know!

I know it's not a S car but i'm hoping you guys can help!

I have a 2000 A6 Quattro 2.5 tdi avant which hasn't got any fuel at the filter housing, i've pulled up the carpet and to my suprise i've got three inspection holes? One has the pump which seems to have failed but whats under the other 2 inspection hatches?

I've removed the top and they look like some kind of sender unit? but why 2? each has a 2 wire multi-plug sooo i'm not sure? i'm reluctant to probe further as i don't know what i'm gonna find!

I've looked at the shape of the quattro fuel tank and think it may be that cos the tank has three main areas, either side of the prop and above the diff, would it have either 3 level sensers or two seperate pumps which pumps fuel from the other areas of the tank to the o/s area of the tank where the main pump is situated?

Sorry it's a diesel but you all seem clued up on all things audi and it is a quattro afterall!

Incase anyone needs to know it does have three sendors, all three are linked which then join to the main car loom through the transfer fuel pump multi-plug.

Turns out the gauge is faulty and it was simply out of fuel. Anyone had trouble with A6 fuel gauges?

They move in an anti-clockwise motion very very quickly

I had problems with my S6 fuel guage, which developed a mind of its own and would show quarter full on a full tank, or sometimes full on a nearly empty tank. In the end they replaced the sender unit in the tank. Apparently this was not the first '6' unit to fail!
