Hello, Well car has been running a little bit lumpy on idle and have been reading about the EGR valve getting blocked up. So today I removed the EGR and anti shudder valve which sits below it. The anti shudder valve was relatively clean but the EGR was completely coated in black carbon build up. Using brake and clutch cleaner along with compressed air, I cleaned both parts up and now the car is running a lot smoother on idle and when driving. It was a little fiddly getting the back allen key bolt out but perseverance paid off! Im also thinking about taking the inlet manifold off and blasting that through as when i put my fingers up inside it seemed quite thickly coated also! Just thought id put it out there in case anyone is having similar troubles!
