Use this procedure:

You need to read the codes from A2 Fuel & A6 ignition on your car as it will have the Hetronic system.

I hope this isnt a daft question but what voltage do I need for the led? 12v?

Thanks...

If you use a 12v LED you don't need a resistor if you use a 5V LED use a resistor between 1k and 2k.
A 12V led is only a 5V one with a resistor fitted.
