The parts aren't really that expensive, it's the labor these places charge an hour. Call around and see who can do it the cheapest, unless you want to do it your self.

Check engine light came on


What do you mean "can't find code"? If the check engine light is on, there is a fault code stored in your onboard computer - that's the way it works. If you are using a generic OBD code reader, that is most likely the reason you cannot find any codes. You need to use a scanner that has the correct software to access your ENTIRE computer network, not just the "continuous memory" or "generic" side of your computer system.

The window problem is a seperate problem and must be diagnosed accordingly.

VW Golf Mk4 1.4 16V AHW, backfires when cold. There were three broken wires, one goes to the EGR, one to the throttle body and one to the mass air flow. New throttle body, Coil pack and wires tested....


Aparently, a "full diagnostic" has NOT been done. If this statement were true, you would have found the cause of your problem.

With that said, backfiring is usually caused by damaged/leaking exhaust valves. Have you performed a compression test on this engine?

If the computer is "getting the wrong reading of the air/fuel mixture", then you should be getting oxygen sensor and/or fuel trim codes.

The coolant temp sensor does not cause the computer to get the wrong reading of the air/fuel mixture, it causes the computer to get the wrong reading of the engine coolant temperature. Although this will affect how much fuel the computer gives the engine, it does not cause it to get wrong readings of the mixture.

Just so you know, "diagnostics" consist of a WHOLE LOT more than hooking up a code reader and pulling codes from the engine computer.
People think that an automotive repair technician simply plugs in the "magic box" and replaces all the parts the "computer" tells him to replace...I WISH it were that simple!

EPC: Electronic Power Control

The ME7 engine management system uses electronic controls to operate the throttle valve rather than the usual braided cable. Pedal resistance and operation matches cable designs so that the operator is unlikely to differentiate. In an event of a failure with either one of the accelerator pedal position sensor (G79 or G185), the other sensor signal would be used in a limited capacity with functions such as cruise control deactivated. If both sensors malfunction, the ECM will limit engine speed to proximately 1200 rpm.

Now as to your question regarding error codes (DTC, SAE/VAG fault codes), as VW scan tool or similar needs to be hooked up to your vehicle in order to read which ones are stored in the ECU. This codes will tell you which area of the system came from and what problem they are related to. Only with a scanner makes all this possible, without it, it would be an expensive guessing game besides being very unreliable.

Maybe you magnetic wheel sensors are contaminated or need replacing, that's what sends the data to the ECM. A faulty wiring could also cause sporadic occurrences when a problem acts up.

If the check engine light is on look at the faults. It could be a defective cam sensor, the timing belt might not be in the place, or a defective mass air flow sensor.
