So I had the MIL light on and my ten-quid code reader says P0403 which is a generic EGR system problem. Doing a search turned up a load of folk with broken EGR pipes on A2s with "my" engine. Anyone had this issue? The valve is 35 quid for one off a scrapper or about 180 so I want to make sure I'm not changing something I don't need to. The fuse is OK.
