I have a engine management light showing on my Berlingo 16 HDI. A garage cleared the fault which was showing a EGR fault. When I removed the EGR it did not seem that bad to me but a gave it a good clean anyway by spraying EGR cleaner into it. Problem is the light has come back on and still showing the same fault. Should I strip the valve and try clean it again or is this a waist of time and rather replace it. They seem a bit pricey and was hoping a good clean might sort it out. Also do you think the cooler might have something to do with it?
Cheers for any advice.
