towbar question

Evening all, my father in law recently fitted a witter fixed tow bar to his x5, after his first trip he noticed the caravan was nose high and after measuring the height of the ball realised it was about 60mm to high ( should be 435mm to the centre of the ball approx from the ground) he's is 500 mm! Could anyone with a fixed tow bar measure there's ? I measured my oem towbar and it's exactly 435mm. He rung witter about it and there a bit confused and have asked there technical department to look into it!

You can fix a drop plate behind the ball to reduce the height to how it should be. I know this does not answer your question directly, but it is an easy fix.

Yep it's standard height. Witter have said they designed it on a x5 with full air suspension and the car should lower it's self to the right height when the car picks up speed! does this happen on x5S with full air suspension?

Might need a proper trailer module fitted? Has it now got one? The module certainly integrates with the self-levelling susp, stability system and the lights/rear PDC.

He fitted it with the proper module etc. The tech bloke at witter seems to think they may have made their bars wrong! Whoops

Oops!! That's a bit of an error. One hopes it was a bad batch rather than all of them. Perhaps a good reason to stick with the Westfalia OEM choice.
I remember once buying a towbar for my trusty (later rusty) MK 3 Cavalier and finding it did not use the factory points and effectively reduced the height under the car by 2 inches! It went back, and a Witter OEM one went on.
