All,
Quick question for the group on replacing air springs with coil springs. I assumed a fault bypass was available for all X350 & X358 models, but the Arnott website states "Instructions to bypass 04-06 Dashboard Warning Light" are included. I called their sales & tech support to verify the bypass was only available for 2004 - 2006 model years, which they confirmed and said there was no bypass available for 2007 to 2009 due to a change made in the vehicle.

Is there any other solution available to eliminate the dashboard warning light on 2007 - 2009 X350 & X358's after the air-to-coil spring conversion is performed?

 

"As far as I know"

The later cars 2007 to 2009 did not have air ride suspension on the front only on the rear. The front were spring over coils. This was done I beleive to eliminate the problem being experienced by some owners on the earlier model cars with the "front" air coils.

 

Actually the front-coil with rear-air spring design didn't occur until the new X351 model.
