Hi guys was wondering about the yellow light that comes on and stays on the dashboard think it is the engine management light sometimes when I'm driving it feels like it loses power ,it is a 11 plate doblo van any help would be appreciated cheers

It's a game of guess what's wrong!?!?

With the best will in the world, we could be guessing for days.

I'm afraid the quickest solution is have a code reader see what stored faults it finds.

My first guess would be MAF or EGR though.....
