Thread: Towing a van with D4 - unhitch at night?

Not a good idea with a vehicle with air suspension that periodically checks that the vehicle is level and will re-level downwards.

I agree with paulgoz about lowering the rear stabilisers only.

The wife and I spend almost 5 months on the road and about half the time free camping.

Generally what we did was leave the rear legs towards the end of camp setup, after opening and closing the car doors several times the car settled to its happy level. We then set the legs down and don't recall any time where the car settled over night upsetting the legs.

We have about 200 kg ball weight.

Even with the car locked up? Do they drop down? I don't know. Surely it wont keep the car level over night? But I can see that if it does drop, the car will put weight on the van. I've got coils but with polyair's so my D2 will not drop.

Yes, they wake-up 2 hours after the last door is closed then every 6 hours thereafter.

Based on the logic of "taking the weight off the vehicle"

Do you (sic) empty the boot area each night when it's loaded?!

Are you serious???

The WSM states 2 hrs after the ignition is switched off so I may be wrong about the last door being closed time.

From the WSM...
Periodic Re-leveling

When the vehicle is parked, the air suspension control module 'wakes up' two hours after the ignition was last switched off and then once every six hours. The vehicle height is checked and if the vehicle is not level within a pre-set tolerance, small downwards height adjustments may be made automatically.

Explains why the battery goes flat reasonably quick.
