Anybody got a vag com I can borrow?

[Chuckster]

My car is overheating and I need to see some readings on my sensors and module to see whats bad before replacing a bunch of parts. I have already eliminated parts that are not bad thermostat, water pump, fans, fan switch(just replaced it hoping that would be the problem.)

If you can further help me figure this out with out a vag com, please do so. Thank you.

This is whats going on, car is overheating at about 240-250 at idle. At highway speeds around 200-220. No DTC's or temp light flashing. No exact on temp but it has not gone pass the last notch/line before the red zone. Fans do not turn on when overheating. The fans do work when turning on the AC.

have u replaced your coolant temperature sensor to the green top?

[Chuckster]

I keep hearing the green top is causing alot of cars to overheat days after installing them. And no I have not.

[Brown Man]

the black top was the one that had over heating problems. they had a recall and replaced the black tops with the green tops

[Chuckster]

Yes I have read that for the 02 and later models. I was searching on vortex and a lot of people who replaced the black w/ the green still had issues. They switched back to the black and it fixed the problem.

hmmm idk

i changed mine out a year ago and it works fine for me.

and when u changed out the water pump, did u replace it with the metal impeller or the plastic one?

[Chuckster]

Metal Impeller.


I just replaced the coolant temp sensor and still overheating. Fans are still not turning on.

Do you know where all the fuses and relays are located? I know of the ones on top of the battery but are there anymore else where(has to be)?

Do what now? Do this to see if the fans work? The fans do turn on when I turn the ac on.
