Hard ride

[zigzag]

I have 4.4 2005 sport with adjustible ride... month ago a found my X resting on front wheels... I took it to the dealer, they fixed it. But since then ride became much harder then it was before and front height is uneven ,difference from 5mm to 12 mm between left and right sides ususally, but sometimes it is even- allowed difference 3mm, by BMW specifications. I also noticed, that when i'm lowering my X its goes lower only 20 mm ( 2 cm).
Anybody knows why my ride became harder?
Any help really appreciated

I would take it back to the dealer and let them double-check that something else was not affected or a setting missed.

I will do it, but I doubt that they will find anything... couse I did ask them to do air suspension test like performance, geometry, responce time..... maybe I should change dealer...

try the same dealership one more time, because they shouldn't charge you extra if they did something wrong..

but if you really are not confident in your dealership, then definately check out a different one.

i'm comfortable with my dealer... they did good job before... and my mechanic, who works for dealer, drives M5...

Does anybody knows default air suspension height for front and rear with 19" rims with sport package?
