I've tried making several adjustments, but cant seem to resolve it.

Ok, there are four problem spots that i recommend inspecting the first would be the air filter.
The air filter may be clogged or dirty. this can decrease the power out put and it can also affect the idle as well. the next check point would be inspecting the spark plugs. make sue the plugs are correctly gapped and are not fouled in anyway. if they are fouled or incorrectly gapped, this will cause the symptoms you are experiencing at this time. Another check point will be the wire set(spark plug wires). make sure the wires are in good condition. remove all wires from the plugs and look inside the wire head t inspect the contacts. they should be nice and clean.if the wires are worn, replace them accordingly. the final check point will be checking the PCV valve. this valve is located Under hood, center, upper engine area, top of engine,
mounted in valve cover. the testing procedure to be preformed on this specific device is stated below.
PCV VALVE TESTING PROCEDURE---
# Check the ventilation hoses and lines for leaks or clogging. Clean or replace as necessary.
# Locate the PCV valve in the cylinder head cover and remove it by pulling it upward.
# Blow into the crankcase end of the valve. There should be free passage of air through the valve.
# Blow into the intake manifold end of the valve. There should be little or no passage of air through the valve.
# If the PCV valve failed either of the preceding two checks, it will require replacement.
You will find the problem for you erratic or low idle in the areas above.
Please rate and god bless:)

well you could try to get a vacuum gauge and see if your car reads what it supposed to and if you buy one it could tell you what it could be.
SOURCE: Idle seems a bit high. Need to know how to adjust and what RPM
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.

internal vacuum leak in carb. replace with weber carb you will be very happy

Look behind the driverside kick panel. There is a removable panel. You will find the fusebox behind that panel.
