The surging is a common problem on the D-jets. Mine used to do that. You do have to reduce the revs to below 1500rpm when cold, but it would be better to get them down to about 1100rpm or less. Then, sometimes the rpm with the engine hot is too low.
The problem is usually a sticking AAV. I had mine out a few times, cleaned it, lubed it, squeezed it etc. I now squirt some WD-40 or similar in before I put it to bed for the winter. I also drive teh car more. All of this helps. If the AAV is free to move, it soon adjusts the idle as it should.
My car is now at ~1100 rpm cold and 700 warm. In drive it is lower - maybe 550rpm. BUT, if I stop for a short while, say for a coffee, the idle sometimes goes way too low - less than 500rpm. I think what happens, is that without any coolant flow through the block, the bulb on the AAV gets hotter and cuts off more air than when running. Have to pump pedal to keep her running sometimes, but only for a few minutes.
Gurunutkins suggested putting in a manual air control valve in series with the AAV - I still need to find one - they have them on mid 90s Volvos and Saabs that are motor driven and can be adjusted using a dash mounted switch.
