The engine doesn't have a mechanical idle speed adjustment - VW/Audi have a software called VagCom (the diagnostic software they use) that is used to adjust the idle - it's completely computer-controlled. You have to change the idle speed using the software.

It is possible that the pump failed because of an overheating problem. Make sure the fans run by turning on the air conditioning. They should operate as soon as it is turned on. Bad fans are a common problem. The pump should not have been leaking after replacement though. Make sure you have no leaks first and foremost. Then make sure the fans work. There is also a fan control module located in the area under the battery, but it is difficult to properly diagnose. If the fans do not turn on with the a/c, you can jump the wires at the thermo switch. One should be power, and when you jump to one wire they should go to low speed, the other high.
If you like you can ask more questions directly, I was a VW master tech from 2000 to 2008.

There's this website www.reliable-store.com They have books on ALL vehicles. it covers wiring diagrams, electrical diagrams, fuse diagram, torque specs, PCV, error codes, fault codes, service info, repair info, parts info, owner's/service/repair/parts/maintenance manuals etc everything totally.. I have 1987 toyota 4runner model and I keep servicing and when needed repair it on my own. worth it !!!

U will have to clear all fault codes first the start the car and let it idle for a while switch off and scan again to see with sensor caused the fault codes the first time

Your best bet , take it to a qualified repair shop .

one simple thing to check first is the ABS connector is easily knocked loose in the battery box.Lift up the upper lid on the box, it is a big oval connector with heavy gauge red wires, push it in until you hear it click hopefully! it'll at least eliminate that.

The other codes are related to the transmission control system. O would focus on getting the car started. I will guess you are getting no sparks. This could all be caused by a bad crankshaft position sensor.

It could also be a computer problem that could be detected if you take it into a service station that can run the appropriate tests.

Replace the retarded ignition switch,the electrical part of the switch only if possible.

If you can find the fuel pressure regulator pull the vacuum hose off and if there is fuel in it it is faulty. http://www.carparts.com/details/Volkswagen/Jetta/Replacement/Fuel_Pressure_Regulator/2001/REPV318101.html?TID=gglpla&origin=pla&gclid=Cj0KCQiAgNrQBRC0ARIsAE-m-1xmnEevPr_ug-dKgXAFQyPgbGUlSDlTcmIxyAfIPuIFWBzuCwzBreAaAoABEALw_wcB&gclsrc=aw.ds

look for a leak from the drain hole under the pump housing, if no leak not a water pump take the car to a radiator specialist shop and have a coolant pressure test done to determine where the leak is if it has plastic tanks for the radiator , they split with time and leak under pressure and a pressure test will reveal exactly where the leak is unlike a guess

problem injectors and seals there is always fuel pressure at the injectors ( up to 65psi) and when you turn off the engine if any injectors are faulty or seals failing , the fuel will be forced into the combustion chambers ,past the ring gaps and into the sump if you use the engine on a regular basis , t you may not have noticed it but leaving sitting , you will get the indicated result

Find the temp flap cable under the control head and follow it to the flap. Check to see if it is properly connected to the flap. Then adjust per the instructions below.

Adjustment

1. Move the temperature control lever to the full cold position.
2. With the control cable attached to the air mix door link, pull the cable housing out and push the inner cable in the opposite direction.
3. Secure the cable in this position with the retaining clamp.
4. Operate the temperature control lever and check freedom of movement at full stroke range.

Take it to a V W Dealer and have them service it.. Make sure you have your transmission fluid changed and get a tune up. Explain to them what it is doing.

You may want to check your wiring harness to that door. The harness runs along the door frame, by door hinge area and it's inside a rubber boot. Most common problem is that a few wires break due to heat and age. If wiring is broken, repair wires if possible. If not possible to repair, recommend you replace the complete harness. If you are mechanically inclined, you will need to remove the inner door panel to access the harness. Once you have the harness removed, there is a label that identifies the part number for this harness. Good luck and hope this resolves your problem.
