Well after a small but required service on the car I had to reset the warning light. The real quick deal to reset all the requested lights on Rover 75 is to do the following
Get a small wire, Turn the key to second position, Short Pin 8 and Pin 4 on the OBD connector for “4 seconds to reset oil light”, “8-25 seconds for the other 2 lights” and this will reset the 15000 service request for oil change. Quick and easy and not legal if you do it without actually doing the service.
