Riding Height

WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Riding height may be affected by faulty electronic suspension system. If height is not correct, see appropriate ELECTRONIC article.

NOTE: To identify installed spring, refer to parts microfiche, contact parts supplier, or remove spring and find BMW number on end of spring. Springs are allocated by vehicle type and, where applicable, by special equipment such as air conditioning, sports suspension, etc. and by date of production launch.

Ensure vehicle is on a level surface. Place front seats in center positions and load each with 150 Lbs. (68 kg). Load center of rear seat with 150 Lbs. (68 kg). Load luggage compartment with 46 Lbs. (21 kg). Ensure fuel tank is full.
Determine actual ride-level height (A) by measuring from wheel arch lower edge (1) to rim flange (2) at wheel center height. See Fig 1. Bounce vehicle up and down. Determine average value for each wheel and establish average value for axle.
Ride height measurement must be within .04" (10 mm) of specification. See RIDE HEIGHT SPECIFICATIONS .
If ride height is not to specification, replace both coil springs even though only one may be defective. See COIL SPRING & SHOCK ABSORBER under REMOVAL & INSTALLATION.
