Audi A4 and VW Passat also use the 1.8T engine and in that configuration it is mounted in the car like in a Tracker so those oil pans might suit you needs better. They are front sump pans with the engine lay-ed over somewhat to the right. The pans are different depending on which year engine you have. If you have an external water pump then it's one style pan, if the waterpump is turned by the timing belt then it's the later style pan. As for wiring if you are using the wiring from the TT you are going to have to deal with the immobilizer which is built into the ECU and needs to read the ignition key through the instrument cluster. There are guys around that can reprogram the ECU to not need to see the key and cluster. Another way around it would be to use the ECU and wiring from an earlier car that didn't use the immobilizer stuff.
