Just had a great day at Oulton Park. Car ran great loads of power with my new de cat Janspeed exhaust, great sound. On the way back up the M6 got the cheak engine lamp on. Pulled over on Knutford services to cheak everything, oil and water ok. I think it's an emmisions thing with the new exhaust. Spoke to a Subaru specialist when I got home and he said it could be any of the numerous sensors on the engine and I need to bring it in to check the error code. Any ideas???

 

Try this chap!!

It tells you how to get the car to display the fault code, and has a chart of what they mean.
