Non-MG cars
My general scanner should eb able to read diagnostic codes for most makes of cars (I may be able to programe spare keys etc but can't guarantee it!)
I have software and equipment to do diagnostic checks and resetting of warnings, service intervals etc, on most BMW models. This inlcudes the ability to programme the ECU (such as to change factory options such as memory seats, timing of lights, alarm settings, etc etc)
I can now also do diagnostics, resetting service lights etc (and probably a lot more once I get round to learning it all) on VAG cars (Volkswagon, Audi, Skoda, Seat, Bugatti, Porsche).
