OK, I'm calling a truce here because this post is way more frustrating than the system I was enquiring about - I just wanted to know if the Disco had a function like the Passat. Turns out the answer is "no"
I don't think it is an issue of me not understanding the function - Like the auto-lowering suspension. I 100% understand why they made it the way they did, doesn't mean I like it, and didn't stop me asking if there was a way around it
