A friend of mine at work has just bought this car. 2 days after getting it, the yellow 'gearbox shaped' engine warning light came on. She took it back and the dealer'fixed' it. They claim to have put a new battery in, but what that would do to help I don't know. Anyway, another 2 days later and it's come back on again. Then today, a week later, she asks me.
I've advised her to get a diagnostic code from a local repairers who have a good reputation where I work. Then take that to the dealer, claim the cost, and get whatever it is fixed.
In the meantime, any hints as to common causes would be apprecieated. Thanks.
