little bit of help please

[baldyman]

Hello guys and girls, ive had my 850 t5 for about 3 months now, it still goes like stink even though shes getting on a bit now. A warning light has come on the dashboard, its the triangle which is meant to mean theres a fault in the engine electronic system. Does anyone know if this is a common fault like the ABS light or whether there is a common fault with the 850 which would lead to this light coming on? If anyone knows anything I would be grateful for the help because i would rather not take it to a garage and do the work myself if i can.

Cheers
