Hi, could anyone please help me locate the fuel pump relay on Audi A3 2.0 FSI petrol. Fuel pump staying on whe ignition turned off. Thanks in advance for your time

Number Description 1 Ignition relay 2 Windshield wiper relay 3 Horn relay 4 A/C switch relay 5 Not used 6 WOT relay (petrol) 7 Power hold relay 8 Fuel pump relay (petrol) 9 Low beam relay 10 High beam relay

Right... ignition off. Keep battery connected.
Procedure:

The way I would do this is to find the fuel filter (not sure where this is on a TT, but will probably require jacking). disconnect the inlet hose and feed that into a fuel safe container/s (size and number dictated by how much fuel you need to pump) with some additional hose.
Alternatively, you can locate the supply hose from the pump itself (probably under the rear seat), or at the engine (though if you are pumping due to contaminated fuel, you will soak the filter with the contaminant, so if you're going to replace the filter anyway...).

Now find the fuel pump fuse.

- At this point, if you can locate the fuel pump relay, you can unplug it and jump the connectors across the relay to energise the fuel pump. Keep the fuel pump running until you have emptied the tank.

- If you cannot locate the fuel pump relay, unplug the fuel pump fuse, and supply 12V to the downstream side of the fuse (left side I think this is). 12V can be supplied via the cars battery, (via a jump wire, or permanent live supply at the fuse box) or by a spare battery or jump pack, but you will need to earth to the cars frame or earthing point.
Run the pump until the tank is empty.

You can also put a toggle switch in line on the supply wire to better control the pump.
And whilst down there, renew the fuel filter.


You could perhaps try a siphoning or pumping from the filler cap, but Audi anti siphoning fillers can be quite good. To get the tank as empty as possible, the fuel pump is your best bet

at about relay ? most cases are in the fuel ECU on the top of the (rear pump)
got any alarm system?

Check your fuel relay and fuel pump on this.

I Would look at the fuel pump relay! What is the picture of?

Hi all happy new year 2016 i have exactly same problem with Audi a3 8p 2.0l fsi 2005 fuel pump running all the Time ( with and without ignition)non stop . For stop it i need to remove fuel pump fuse.
I think this part is defective

I want to have helps before buy it

Thanks in advance.

try connecting pump direct to battery to see if pump works if it dose then a fuse or relay check all wire connections

The fuel lift pump relay is placed in the fuse box / relay plate fascia 2 for 2007 Audi A3 2.0 TDI. The fuse box / relay plate fascia 2 is placed above pedals behind a plastic cover. See pictures below:

The fuel lift pump relay is placed in "2b" position in the above picture.


Please do rate my response. Thanks!

it is just a matter of unscrewing the cover in the trunk,removing the wires,then unscrewing the pump cover.make sure the fuel tank is not empty as an empty tank is highly explosive.

Hi, did you sort the problem with your tt? I have exactly the same issue, apx engine, will not start, ecu not readable by vagcom or snapon scantool? Any advice gratefully recieved. Craig.
