But if MAF caused this wouldnt it cause my obd scanner to show fault?
The reason I bough obd scaner was the gear box playing up so I dont think it would cause any issues.

Car has done just over 50k km which I dont think is much.
There r no dipstick on these vehicles, I think it's best you check the fault code on the gearbox control module before u start throwing money on stuffs. Also have u tried removing the Bluetooth kit? They interfere with th g/b module especially if your car still have the unmodified module from BMW. Ignoring maf sensor can cost u your gearbox they don't always throw codes. I learned this myself.
