Touareg :: A/C Won't Work Efficiently?
May 29, 2004
I can't quite owkr out what is going on, but my A/C sometimes seems to be working too well and other not so good. For instance, last night I got in the car, 95 outside, and inside the A/C was going flat out (set to 65). The air from the middle vent on the passager side was very cold, from the drivers side it did not even feel cold and in the back also not cold. After 10 minutes of driving the car was barely acceptable. Went flying for 2 hours, came back, now temp outside was down to 90 and the car got cold very quickly (<5 mins).
In summary it would appear that if I do a lot of stop start driving, the A/C looses efficiency.

I've only had my Prius C for a few days.
I'd like to know more about how the ICE shuts on and off efficiently. As a teenager, I was told it was a waste of time to turn a car's engine on and off to save gas. Now, I've got a car that turns its ICE off every minute or two!
I did some searching on YouTube, but couldn't find anything that talked about this. I suspect there is some special injection scheme to pull this off.

Ever notice that the Homelink won't work unless the car is turned on? Not very useful for putting the garage door up and down as you don't want the car running BEFORE you put the door up. I had two other cars with Homelink and both worked at all times. If VW can make the radio work all the time they could certainly do the same with the Homelink controls.

I have an 04 T-reg w/ 15k miles on it, the problem that i am having is with the A/C. It works for the most part but some days its just not that cold. Usually when idling or after returning to the car after 30 minutes or so the a/c just doesn't seem to recover. Its not warm air but its certainly now cold air.

2005-V6 with 83k miles. The A/C did not work after driving 20 to 25 minutes when the temperature hits 85 degrees. Usually did not work all day but started to work fine the next day and if temperature did not reach 80 degrees, will work all day.
The compressor did make a humming noise that you can hear with the window close.
Finally took the car when the A/C was not working and they saw it at the dealer. After a week I got a call today that the temperature sensor was bad, they are testing and should be ready tomorrow.
Will that fix the issues? what about the noise coming from the compressor.

Have one of at least four different software codes, depending on your version of the TPMS controller. For the old controller (which I used to have, and which is present in, for example, air cooled rig), the coding is 0012339. (There is also 0010339.) The new coding below is only if you have coding 0210390 and possibly if you have coding 0211390. The old coding does not work with my controller, and I do not know if the new coding works with the old controller.
Use VAG-COM:
1. to put the option to turn TPMS on/off into the MFI.
2. to get "inflation info" back into the MFI.
Change the software coding to:
0110390

So, I was over rearranging some stuff at the self-storage unit the other day and was getting warm, so I took off my coat, with the Treg keys in the pocket, and tossed it through the open driver's side window. Inadvertently pressed up against the door lock button in the handle and guess what....the doors locked, contrary to what is supposed to happen, or not happen that is, that being that the doors are not supposed to lock with the button when the keys are in the car! Good thing the window was down!

My V10 has the wood steering wheel, and the button to turn heat on and off. I have not been able to get this feature to work. On questioning the dealer they said that this option was not offered in Australia. It seems unlikely to me that a manufacturer would make two types of wood wheel as the production run would be more expensive than just one.

While doing some rewiring of my xm satellite radio in my car. I seem to have broken something electrical (besides the wood trim!) For some reason now the xms cig plug wont work. Though the other one next to it does. I've already swapped out the cig plug with another to see if it was just the plug and that didn't work. The two outlets aren't on separate fuses are they?

I recently upgraded from the CD radio to the nav radio and just noticed a problem. My center console speaker (under the windshield) no longer work. All the other speakers work properly.

For some reason the wipers only work while moving. At a complete stop, slow, fast, intermittent and the wipe mode do not work. If moving forward all functions operate per the owners manual. The rear works perfect.

Since the day I purchased my Touareg, the heated steering wheel has worked inconsistently (usually not at all). I bought it in November of 2003 and thoughout the winter I brought it in 5 times telling them that it would not turn on when I started the truck. Of course, having an early VIN truck I don't have the symbol that tells me the wheel is supposed to be heating, so I have to guess... But with below freezing temps, I turn the truck on, push the button and nothing happens. After 5 minutes I push the button again and still nothing happens. Every time I took the truck in, the dealer told me there were fault codes in the truck saying that the heater was stopping because of a lack of required voltage. Several electrical fixes later (some parts blew out at various times and were replaced), it seemed to work. Then Spring came and it won't turn on until fall when it gets cold again... This past fall, I reported the problem again and they put several updates and fixes into the truck but they have not been able to fix the problem.
Today, I went back into the dealership and they told me this was "normal"... The note they put in was as follows:"Tested steering wheel heater in GFF. Steering wheel heater is not failing. Customer will only be able to tell if the heated wheel is working on really cold days. Steering wheel only heats up to 77 degrees."
When it works, there's no mistaking that it's on and it does shut off when it reaches a warm temperature. But when it's 25 degrees out and it doesn't warm the wheel - it seems to me that it's broken... Have such a hard time telling when their heated wheel is working?

I have driven a Phaeton in Germany and have a 2004 touareg V8 with full nav and premium radio etc. The basic dash layout is very similar and the nav seems to be identical. Is if possible that whatever phone system is supplied with the Phaeton will work on the Touareg???

I have the Winter Package on my Treg and when I can get the heated steering wheel feature to work it's awesome. My problem is that it doesn't ALWAYS seem to work... Sometimes when I push the button, nothing happens. Other times, it turns on and off on demand. The salesman suggested that it might only work when the heated seats are on but that doesn't seem to make it work either.

When I went to unlock my trunk hatch last night the remote did not work. I then attempted to unlock the doors....still no joy. I attempted to lock the doors....nothing. I then manually opened the door, fearing my battery was dead (after reading the numerous battery threads) and the put the key in the ignition and it started right up? I then took the key out and locked the door using the reote. I unlocked the door and opened the back hatch with the remote. The only thing I could think was my step mother had unlocked her Dodge Durango that was parked next to mine...and maybe this confused my poor touareg!?

Is it true I can never have different types of tires between front and rear? Even if the size is the same? I put on winter tires the other at the front. The result was a nasty noise when I would accelerate and release the pedal suddenly... I had to switch back to my old summer and (unequally) used front tires.
I wonder why that is. Furthermore, the wear on my tires is not equal between front and back.
