Well thought I'd have a look at my egr this morning as I was keen to see how bad it would be at low mileage. The answer , bad. I was very surprised to see the amount of carbon in it. Anyways gave it a clean popped it back on with two new gaskets and jobs a good one. Sorry I forgot to take pics if valve once cleaned. The only prob I had was after I'd put it all back together and was sat in the kitchen having a celebratory brew, I had a strange feeling I'd put one of the gaskets on the wrong way up ( exhaust side) as there's a lip on one side, I ran my hand round whilst engine was running and all seemed fine, may double check this later. Car feels better now so alls good.
