Touareg :: Whining Noise Related To Stepper / Differential Control Module
Oct 13, 2004
I had the differential control module recall/flash performed last week and now the car makes a whining noise at speeds north of 35mph. The noise seems to emanate from the front of the car (near the radiator). The dealer was able to hear the sound -- and unable to diagnose the problem. They reflashed the stepper -- and the noise remained.
They moved the stepper motor, drove the car -- and the noise remained. Finally, they put the stepper back in -- reflashed it -- and then the noise went away. Subsequently, I drove the car noise-free for about 250 miles (over several days) -- and then the noise came back. I'm also having the same problem that others report about the tight-radius binding when turning (which the flash was supposed to solve).
questions:
1) any experience of whining noise after the flash recall
2) i see that some had the stepper motor replaced...what was the underlying reason?
3) it seems that the stepper is the problem -- but could it really be the differential that's not keeping the right ratios?

I've had my 2006 V6 for a few months now and I've encountered a few annoying little problems that I would like more information on before I go to the dealer for my 5000 mile service...
1) Every time I start the car and pull out of the driveway there is a rather loud clicking noise. It sounds like the car is slipping into gear. There is no jolt or hesitation, and you can't feel anything, you just hear the noise. It happens when I go over about 10mph, just once, every time I start up.
2) At higher speeds when I start to accelerate say from 50 to 70 mph there is a high pitched whine. It is like the car is winding up before it takes off.
3) Sometimes there is a clicking noise coming from the dash board. Like an electronic clicking noise when you click on a link in a website. It clicks a dozen times and then stops.
4) One time the radio controls stopped working and the radio control panel started blinking on and off rapidly. After about three minutes everything returned to normal.

I now have a new amp, the remote range fix, alignment since Egg pulls slightly to right and the steering wheel is off center. But they were totally clueless about the stepper motor issue/transfer case control module, and after going through all the printouts, they know about it now!
And I had my first oil change in 8 months at 2200 miles.. My question: How is the stepper motor replaced?

I recently received an airbag fault light so I figured that I would scan the module for error codes. This is what I came up with:
Control Module Part Number: 3D0 909 601 C
Component and/or Version: 05 Airbag 8.4E++H01 0352
Software Coding: 0012341
Work Shop Code: WSC 31414
Additional Info: 7L0959339B BF-Gewichtsens. 005 0006
Additional Info: Geraet 00000
2 Faults Found:
01217 - Side Airbag Igniter: Driver Side (N199)
001 - Upper Limit Exceeded - Intermittent
01316 - ABS Control Module
004 - No Signal/Communication - Intermittent
Has scanned the car while had the airbag fault present and if so, is this the usual harness that needs to be changed?

I purchased a 04 V8 with 22K miles. Very nice ride and huge upgrade from a Grand Cherokee. After noticing slow cranking, I took it by a dealer where we tested the battery. Electronics and battery tested OK. Dealer advised to lock the doors at night when parked in my garage.
I am still having slow cranking, and now experiencing the Traction Control module flashing and error message on the screen. ( It will disappear after I restart in a few minutes.) I am also experiencing a message that the computer is shutting down the consumer electronics.
Alternator showing 13.75-14 volts at first start up, returns to 13+ volts after 15 minutes. Cables, poor battery? I want it to start after sitting at the airport for several days.

Recently I've had problems with my DRL (Day time Running Lights) Control Module. When I start the car, the DRL starts to make a loud buzzing sound. When I turn on my High Beams, it stops making the noise. It sounds like there's a relay that Isn't working like its supposed to be. So, I've thought of replacing it, but I`m not sure if its the DRL that's defective or just a wiring problem...

This noise has been posted several times recently and I have also experienced similar sounds. Whining in the drivers side dash area. Dealer states that it is fuel pump and that it is normal. Well, it has been a lot colder here in the last week and the noise has become louder, a couple of times to the point that it was hard to carry on a conversation with someone in the vehicle.
So I started investigating and found that if I turned the HVAC fan all the way OFF, which turns the system off, then the noise is gone. So my noise has to be associated with the HVAC. Complaining of this same noise coming from the drivers side dash? Also found same noise when I would use the REST.

Have some 'whine' coming from the rear differential under deceleration. In my case it just started occurring last night and seems to be audible over 55MPH and while in 5th or 6th gear after I let up off the throttle as to engine brake.
It seems like the answer or solution pertains to the input shaft pinion retention nut eventually backing off, as well as oil starvation to the unit, but has this actually been confirmed? My rear diff was replaced over 4 years ago under warranty after it failed and enduring 2 wheel drive for a bit.

While I was driving today, I noticed a "whining" noise that sounded like a belt squealing that got louder as I increased speed. I pulled over to check the see if it was in fact a belt, and when the engine was revved in park, I heard nothing. As soon as I started to move, the noise started, then increased in volume.
I assume that this is some sort of wheel related problem.The sound seems to be coming from the right rear wheel. I just got back from the dealer. The tech said that the main bearing in the drive shaft is bad. They have to replace the whole drive shaft to fix the problem. I am glad that it didn't completely fail while on the interstate, I bet it would have done some damage.

I've got a 2004, V8 with about 65,000 miles. If its 75 or above and the ac is running the HVAC will start this whining or chirping noise. It seems fan speed related. Its coming from the passenger side, not the drivers side as some of the other posts mention with their situation.

I took the 2004 Touareg V8 to diagnose a groaning noise and they said it was alternator related. The car is charging and running fine. They've ordered the part and said its a 10 hour job. What this could all be about? I've got about 26,000 miles on it and have not had any serious problems. The main one was replacing the battery cable about a year ago. I've had a really good vehicle and enjoy it.

I have an early V 8 04 Touareg with over 60,000 miles. I have had no serious problems and it has been remarkably reliable until recently. I have had multiple "running gear workshop" faults related to the air suspension in the last month.

I bought a 2012 Prius C with 17,000mi on it in February this year(2015). The body control module apparently went out about a month after buying the car. The start-up screen would not say "ready" and shortly after turning the power on, the warning came on: stop the car immediately, something wrong with hybrid system, get to nearest dealer, etc.! it also appeared there were suddenly a number of other malfunctions in various systems as various warnings came up, one of which concerned the power steering.

I have a problem with the Bold-Sport camera, but am not sure if it is the radio, the camera, or even possibly a fuse. I get a fault code with vcds that says the rvc control module intermittent/no signal. Once I clear the code, and put my car in reverse with the headlights on, the camera does not work, or works for a second, and shuts off. If i turn the exterior lights off, the camera seems to function normally. As soon as I turn exterior lights back on, camera no longer displays again. I have been having some problems with the rns-510, so am assuming it could be the radio, but am not too sure. The problem I have with the radio is that sometimes not all the interior light hard buttons light up. I will post up a pic as soon as I can.

My car was in the shop for 3 1/2 months. When it went in the power trunk worked perfectly. While it was there the comfort battery died and was replaced by the dealer. Since I got it back I've discovered that the trunk no longer functions properly. The trunk control module doesn't seem to remember the coding. Now, based on advice from VW of America, the dealer wants to replace the trunk control module and charge me approximately $750 to do so. I'm left with the question of whether the failure is coincidental and my responsibility or was inadvertently caused by the dealer through some type of voltage surge or something like that?
