I've go a bit of a problem I need to read my engine codes as my car is playing up but my engine management light doesn't work even when I turn the ignition on it doesnt illuminate does anyone know what size bulb they take.
Thanks in advance
Try swapping the bulb for a working one already in there first.
There are other ways of testing it to diagnose as I had same problem so search for my thread on rev 2 turbo ECU capacitors.
