| Tyre changing & air suspension |
|
Has anyone encountered problems getting the wheel on and off the hub with air suspended vehicles?
Instructions says to put car in extended mode to change tyre. I found that I had to jack the car up a long way to get the wheel off the ground as the suspension kept dropping. Eventually got it off, but when I went to put the repaired wheel back on the hub had dropped further than I could jack the car up, hence I couldn't get the wheel back on 
I tried starting the car and lowering the suspension, hoping that this would raise the hub. This worked momentarily, then the car went into extra extended mode (as it thought that it had bottomed out due to being jacked up) and dropped the hub even further. 
Luckily I had a second jack handy to put under the wishbone and jack up the hub to get the wheel on.
Two thoughts came to mind: 1. What if I didn't have another jack, and 2.  smart ass car.
Any suggestions? '06 TDV6 SE AUTO BUCKINGHAM BLUE

Seems very strange!!
I had a puncture a few week ago and changed it myself.
Did everything by the book and experienced no problems.
Don't think you mentioned if it were front or rear - mine was front.
Think maybe a discussion with the dealer would be in order. ...... always on the road less travelled 🚧

The handbook is total on this subject. Far easier to do with the car locked into access height, although somewhat harder to get the jack in place. One of the reasons I've bought an air jack 
I guess removing the keys from the ignition wouldn't have helped?  I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Leave a door open... it stops the suspension doing anything. Rear hatch excluded as it will still drop with it open.
And off road height is what you need to set (probably so you can get the spare off).

Sorry ronp, it was the back wheel. Yes I had to change a front wheel a year ago and had no problems. NoDo$h, I thought of locking the car in access height only after I got the wheel back on. Will try that next time! '06 TDV6 SE AUTO BUCKINGHAM BLUE

Had a flat a few weeks ago (nearside rear), changed it as per the instructions in the manual and all was fine, I used a 3 ton trolley jack posiioned under the jacking point detailed in the manual.
In fact as I was jacking the vehicle the suspension lifted that corner just as the wheel cleared the ground, scared the out of me. 2012 D4 - SDV6 XS - Firenze Red

Hi d3syd, as simon posted, leave a door open.
I sure this suspension lockout while a door is open was probably designed to stop a door being damaged if it’s opened over an object and the vehicles is lowered but it also works as a safety device while trying to change wheels and foe the same safety reasons, this info should be made very clear in the owners manual.

Also, somewhere in the book (or latrest book) it says to take the key out.
That possibly does the same as leaving the door open.

Unfortunately removing to key does not stop the suspension from trying to level itself.
I think you will find that the instruction of removal of the key is more to avoid having you or someone else accidentally starting the vehicle while it’s jacked up.
As posted above not even leaving the tailgate open will stop the suspension from working.
To my knowledge only having a door, any door, opened will override the suspension operations.

I think the best suggestion is from NoDo$h - lock it in access height. That way you don't have to jack the car up as high with that unstable sissor jack. There should be enough clearence to get the spare off I'm sure.
Oh by the way, I forgot to mention in my original post. The wheel brace is equally , I broke it tightening up the nuts!! It's made of mild steel - ridiculous '06 TDV6 SE AUTO BUCKINGHAM BLUE

You can lower the spare and get that out before dropping the car to access height. I don't use the supplied brace; I've got a breaker bar with the right size socket welded to it as the original is made of recycled tin  I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.
