Re: 4WD Problems
Hi Franko,
In the 3 years I had my xtrail (problem free) I've never heard of anyone in Australia getting a dud xtrail.
This however is completely different in other parts of the world, especially the diesel version.
I'm positive that you have overloaded your 4WD system and stayed in Lock mode longer than you should (as Rich has stated above)
When I was a Stockton, I have only used the Lock mode near the Ship-wreck (very soft sand) and stayed in AUTO for the duration of the trip, which was more than enough.
Having said the above and for added peace of mind, mention it to the dealer at the 1000kms free service.

Re: 4WD Problems
I am a regular to the Stockton Beach area and used to live at Cronulla. (so Kurnell was my backyard) To date, no problems with the 4x4 system on the exee.
As mentioned earlier, it is better to drive in the auto mode or if at low tide with a good section of hard sand, I even use standard 2wd.
The issue on lowering tyre pressure also contributes to the engine overheating.
I found the perfect tyre pressure to be between 16 and 18psi. This allows the tyres to bag and float over the sand ridges. Don't guess, buy a quality tyre gauge. I use 'staun' tyres deflators, where you can preset the tyres pressure and screw them on. They then release the air in the tyre to the preset pressure. There are four in a pack, so it's quick. www.staunproducts.com About $40 from memory.
On the desert tracks, we vary between 20 and 22psi, due to the increased loads.
If you try driving above this pressure, you will find that a small pocket of sand builds up in front of the tyre, causing it to try and crawl over this mound. This confuses the 4x4 system, increases the engine revs and also causing overheating in the transmission.
If you try and go below 16psi, the rim will spin inside the tyre. Been there, done that. Not a good feeling.
Try it out. Next time you are on the soft sand walk next to the front tyres and look at the mound of sand that forms there.
