I've got a small trolley jack that has it's own plastic case. It fits under the suspension (control arm/airspring point), and then lifts the vehicle enough to change a tyre.
It's rated at 2T (or 2.5T), from memory. I bought it after reading many posts on this forum - it's stable, safe, really easy to use - IMHO better than a bottle jack (and we shouldn't even be talking about the OEM item as a jack - it's terrible!).
I got the jack from my independent mechanic who does all my servicing - he recommended it specifically for the D3/4, due to capacity, overall height, ability to get under the suspension arm and lift height.
Also, I don't change the height of the vehicle to jack it up - although I do pull the fuse on the air suspension whenever i'm jacking the car (or getting underneath it)... I know people say "open the door", but I don't trust it!
In my view, this is the only jack to use!
