4 wheel drive problems reduction on


Go to solution Solved by Kamil Barański,

Recommended Posts

Hi,

We have a heavy snow here in Poland so I wanted to use reduction to get home safely.

Unfortunately a massage showed up on the screen which says that "4 wheel drive fault......"

Car is in the garage now and I cannot get it back to normal 4 wheel drive - reduction is still on. No chance to get it to second type of reduction. Massage stays on

I had 2 trials where I managed to get it back to normal 4 wheel drive as I thought that maybe snow did some damage or water etc. nothing.

I am looking at many topics here on the forum and it looks like it may be the servomotor?

The transfer case was not used very often.

Battery was changed 7 months ago.

Any ideas where to start?

No chance to connect it to durametric as I am over 100 km from Warsaw Porsche Stealership.

Need Your help Guys as I need this car to run smooth again.

Oil in the transmission was changed 3 weeks ago.

Anything would be a guess without the codes. I would get online and order a Durametric cable and have it overnight shipped, when you mention the dealership I believe you are meaning PIWIS vs Durametric. In my case my durametric cable was a tool I ended up using nearly every month on my CTT.

This was posted quite a while ago, it worked for me:

0. Stop and start your engine (in case you got already fault message)

1. Activate off-road /Low Range mode/ driving program (use rocker switch) with gear shift lever in neutral position

2. Drive your car for a while (move forward/backward several meters)

3. Activate on-road /High Range mode/ driving program (use rocker switch) with gear shift lever in neutral position

It may "heal" your all-wheel drive system, e.g. resistor, which identifes mode in which system is and generates fault message when corroded - it happens when you do not use this feature for a long time...

Also, you mentioned the battery was replaced 3 months ago. I would also HIGHLY recommend you disconnect the battery and clean your ground connection at the battery and at the chassis.

Hi All,

Pkscheldt many thanks for Your help.

It turned out that the problem was that servomotor could not move itself fully to the low range position and that is mainly due to the lack of use of low range. Servomotor was replaced (we used one from VW Touareg) and that solved the problem

      hi guys,
      I have a 2012 Cayenne S which has done about 56k miles. When I turn the steering and press the accelerator, the rear left tyre judders. My brother observed that the wheel looks like it was 'locked'. 
      My mechanic disconnected the transfer case motor, and after he did that, everything was back to normal (there was a 4x4 error as the transfer case motor was disconnected). According to him, since the transfer case motor is disconnected, the transfer case was not being used and he came to the conclusion that there is a problem with the transfer case. Another gearbox specialist I consulted with said that the problem is due to the transfer case motor. According to him, even though the motor is disconnected, the transfer case is still being used. He also gave me some other reasons which I forgot. I am not sure who to believe.
       
      BTW I have  also done the following:-
      1)Change the transfer case fluid
      2)Change the rear axle fluid
      3)Refurbish the rear left driveshaft
       
      The problem became worse after doing the last 2! both the transfer case & axle fluid were dirty but nothing serious.

      Hoping to identify a root cause of multiple transfer case failures.  2012 Cayenne S purchased CPO with 43K.  Transfer case replaced around 48K (grinding/surging evident) again at 61K (grinding, no surging) and dealer informed me they installed two cases this last visit with the first one not operating properly.  Returning to dealer today, 62K, grinding/clunking particularly evident on left hand turns but not exclusive and while frequent it is not a constant occurrence. 
       
      Hard to imagine randomly getting multiple "bad" transfer cases and suspect some other gremlin is the root cause.  Has anyone experienced a similar issue or have a suggested direction (differential?)  I can pass on to the Porsche techs at Annapolis Porsche?  Rolling out of warranty in two weeks so a bit concerning.
       
      Thank you,
      Rich

      Can anyone help me identify a fluid leak? While changing oil on my '04 Cayenne S, I noticed a small leak coming from the drain (weep) hole of what I would normally call the bell housing which I assume is part of the transmission housing. There are 3 small holes in a row which appear to be drain holes. The fluid has the consistency of 90 weight oil. It is amber in color. It's not motor oil or transmission fluid (which I think is colored Red). Thanks!
