Ever since I switched over to BC Coilovers last month, my battery keeps dying every 2nd day without charging. I switched out the battery and still, absolutely nothing if i try to fire it up after sitting for a day.

Do I need to somehow disengage the airmatic system? is this causing my battery problem? Thanks for any help

No such issues here.

I removed the Airmatic fuse as well as the pump. Car displays a 'too low' warning at startup, that's it.

pump is probably running. Pull relay for pump and unplug module.

do u have bc coilovers how are they? U use non airmatic control arm rear control arm?

cheers

Have been running KW V2s for 2 yrs now on W211. Removed the pump at the time of install. Did not remove the fuse/relay, though that would probably be a good idea. Haven’t had battery issues, but display says “car too low”.

Adjust the linkage arms so the module will see it higher

May sound like a dumb question, but I have to ask, since I’m not entirely familiar with automotive terminology in English:
1. Could you please specify which arm you’re referring to as “linkage arm”?
2. Would such adjustment increase actual ground clearance? Possibly at the rear axle?

Thanks in advance for your input.

Also, it has been tough to achieve adequate wheel alignment, likely due to the 0.5-1 inch drop with KW conversion. The techs are able to get the rear wheels within spec, but the front camber has been wearing the inner edges of the front tires every 7k miles.

What is the current camber setting on the front wheels?

If the display is showing car too low then the the linkage arms on the level sensors can be replaced with adjustable ones so the Airmatic control module sees it riding at a height within specifications now that it is sitting lower on coil overs.

You need to code out the Airmatic in the instrument cluster and gateway control unit...
The level sensors will only be used for auto height adjustment of the Xenon lights. You need to pin the 6 level wires from the airmatic control unit into the headlight level control unit. If the sensor voltage is out of spec you can adjust the level links.
