Warning lights.

[Ian Farey]

Hi. 

I need a bit of advice. I have a Forester 2.0 diesel. I get the engine management light and the light of the car with the line slashed through it illuminated. But it doesn't always come on. I seems to happen randomly. The traction control sensors have been checked and I've been to the garage,and they can't find anything. Can anybody help? 

Thanks in anticipation.
