My brother and I, him being the more mechanically minded, have cleaned the EGR valve thoroughly and checked the small pipe that connects to it to make sure it has vacuum. It does. Following the pipes back to you The EGR light came on and had dealer repair it. They said and showed me it had seized up ,cost £205. Prior to that two weeks before we had towed our caravan for about 1500 miles up hills and down dales as they say so thought that the system would have cleaned itself out.Its the 140bhp with dsg Elegance 55 reg.now done 47000 miles.

But I cannot get the rear EGR screw/bolt out, I can't even get a torx bit in the screw. The side EGR intake pipe is blocking access to the bolt, but even with the 2 bolts out of that, it won't move an inch.
