..

The ECU is located on the drivers side under the plastic engine covers between the firewall and engine bay.

What model A3, A4, A6, A8 ? Or have you the part number ?

Next check the relays.

Alright it gets complicated...
I'm assuming you have a 4L (2005-2015) model.
It will be in the under bonnet (hood) relay panel.

It can be any two of five relays depending on engine and year!
For petrol engine models up to June 2009 it's relays A1 and A2.
For petrol engine models from June 2009 it's relays A5 and A6.
For diesel engine models (3.0 and 4.2) it's relays A5 and A6.
For diesel engine models (6.0 V12) it's relays A2 and A4.

A4 CARKNOWLEDGE

pump relay is in the No2 fascia plate which is situated just above the the box behind the Knee pad of the dash on the drivers side.Looking at the relays it is the first from the left. Hope that helps

I think on top of the transmission, the one has a wire, and looks like a sensor. To remove, need a 19mm , open wrench or socket wrench.

do you mean how... or where is it located.... look under the hood for the fuse panel located there. basically you find the correct relay ... pull it out and replace it. there are more relays under the dash and i've heard the audi's also have them in the trunk.
