2010 E70 X5 3.0d - High Rear Suspension

Sm[]key · Post by **Sm[]key** » Fri Nov 25, 2022 11:02 am

Got a number of faults during a long drive last night:

A3C7 - Air spring_FALL_NETWORKMANAGMENT
60B0 - Flat tire Indicator: RPA inactive due to excessive air spring height difference at rear axel
5FB4 - Energysaving mode active

Both rear air bags are at full expansion and the rear is riding high.

Just about to have a look underneath, guessing its a level sensor issue?

Level sensor is plastic so could have broken.
Also check the contacts in the plug for dirt/corrosion.

Fitted new level sensor today, old one when taken off didn't have smooth rotation of the actuator arm.

At full air spring pressure the ride was very bumpy, even more so when going over speed bumps!

Suprisingly taking it for drive didn't sort the levels out.

Plugged ISTA in, inputted wheel size and dimension from bottom of rim to wheel arch on both wheels. Took it for a drive and the height was corrected.

Repeated the same again and all is good!

Glad you got it sorted out.
