    I've read a bit about EGR Valve issues on the 1.9 CDTI and have thoroughly cleaned the EGR valve and refitted. NO joy. Swirl Flaps are intact and working fine (From what I can see). Removed and clean the Torque Sensor as well cos that was boggy! No joy either. Still low power through the gears...
