Where is the service indicator reset port located on a 1996 BMW 318?

open the bonnet/Hood. Stand at the front of the car looking at the engine. Just over halfway back on the left hand side there is a round black pastic thing. Lift the lid off this and you will see some pins. Locate pins 7 and 19. Make a connection between this two pins with a pair of scissors or paper clip. 4 seconds resets the oil service, 11 seconds resets the full service.
