Hi, car has transmission warning light on. Have to change gear on paddles (it's automatic). Limp mode I think it's referred to. Expect my local dealer is closed so a friend brought around his computer thingy and plugged it in. 24 errors! Suspected EMU but he doubts that as low mileage. He fitted a new mass airflow sensor but that made no difference. He asked whether a software update has been done recently. My last service was about 2 months ago so expect that would have been done then. Any suggestions please?
