There are a couple of things that come to mind. One is make sure the EGR Valve and intake manifold are not carboned up. I normally have to clean them every 60 to 80,000 miles. It will actually close up with Carbon and restrict air flow and make the EGR valve malfunction.
Secondly, the diesel pump may just have a lot of wear and it is putting out too much fuel at idle. The only way this can be checked is by the dealer with a VW specific scan tool such as VAG-COM. With this tool, you can go in and look at the the pump timing and start injection quantity.
I have the start injection quantity many times but you have to have the software and login to get the readings. Most dealers will not do this but would rather sell you a pump if it is off.
Remove the hose from the intake where it connects to the EGR valve and look at the inside with a flashlight. See how much carbon is accumulated. This may not solve this problem but will help with starting and performance issues if corrected.
Good luck and hope this helps. To adjust the Idle, it needs to be programed in to the ECM so i am thinking that it's a Carbon issues that is restricting the air flow which the ECM is compensating to keep the engine from stalling.

You might also check the single injector, had a friend's that the fuel pressure regulator had been messed with and was over-pressurizing the injector, that weakened the injector allowing it to flood at idle and also when cut off (the injector was leaking)

Yeah it sounds kinda high. There is no adj except for the idle screw on the throttle, the computer does the rest, if it has one. If not, then you can adjust it some how. If carbureted, check for 2 little screws in the front, and check the choke, If throttle body, then just the idle screw, the idle should be around 1000. Hope this helps.
