My AUM has an oil sensor, I would imagine yours will too. If in doubt, have a quick look under your car.
If there's a black 'box' bolted to the centre of your sump with a lead coming out of it then you have the sensor. Don't bother getting the loom from ECS, the part numbers are listed on there website - write it down and take it to your local stealership / TPS and buy it from there and save the postage costs.
I paid less than £30 for mine, haven't got round to fitting it yet though.....
