4.8iS ride hide measurements (need your help)
 

Had a ride height sensor replaced drivers side front after my 4.8iS got stuck in the off road posistion for a while. It fixed itself but was randomly throwing a warning message. Tech had a ton of issues getting the system reset and I am convinced the vehicle is sitting higher than before. He recalibrated and I am suspicious he got it wrong.

Can someone with a 4.8iS on stock 20s do a measurement to the underside of the black plastic overfender from the ground across the center of the wheels front and rear so that I may compare ?

I will measure my heights shortly and add to this thread.

FWIW, I have read ALL the info here on 2 axle air suspension so I am forewarned and mindfull of the fact that this may get expensive as I am now 2k out of warranty :rolleyes:

Many thanks

2006 4.8iS

i did these measurements this summer for justin at normal ride. at normal height front are 27 1/8 rear are 27 11/16

i went from the bottom of the rim to under the flare.

You should be able to find an independent BMW shop with the right equipment to calibrate the suspension.

I had mine lower my iS a bit and it turned out great, only cost me $50

Any suggestions how to find them ? I would just take it back to the stealer who did it but they are in VA and I am now in PA.

Thanks

little bit different question.
Bmw dealer replaced air shock observer struck front right. Because every time when car would sit for a while, i would notice only that side is lower than other, and after a while LEVEL SYSTEM INACTIVE come on. Right now.. i notice just few hours ago. a notice front LEFT is very low. as soon as i turn ON the car, car went UP. i will try make a video of that

What part of PA?

Well that explains a lot I have 30 (27 11/16) Rear and 29 (27 1/8) front.
My guess was it was sitting about 2" to high. Rides like it as well.
I have an appointment locally next week ... I amy start selling off furniture to pay for it :rolleyes:

Can someone tell me is it normal for 4.8is after like 4 hours to sit lower or it should stay the same height.


Thank you

u might have a bigger problem if that's the case. might be a leak if it drops like that.
