F55 Delete?
I’m sure this is in an old thread somewhere.I notice in my 06 that the ride control switches are in mop.I have seen posts where these were deleted via. tech II.Is this hurting my car in anyway? I’m pretty sure the display came up with some error with a previous owner and had it dele.Just wanted to know what I might do to get it back.Probably big bucks.Car rides and handles great to me. Thanks guys

F55 system, besides the controller and wires, is the ride height sensors, and the MRC shocks.
So for the most part, F55 delete is done, when the $450 per shocks start to go bad,and they are changed out to standard type shocks isntead. Also to point out, the first C6 F55 programing where not the best, the systems was running the FE1 springs, so the system was really meant for a smoother ride in tour mode, and not to take the system up to a Z51 firmer set up in sports mode instead. This did change on the GS F55 models, since you have the FE3 set up, with MRC shocks instead.
Best guess, is the ride height sensors where not pulled, all that would need to be done is to reinstall the MRC shocks, then turn the F55 module back on in the BCM to take the car back to the basic base type F55 set up.
But, if it was not only just shocks, but other parts of the suspension system changed out to bring the suspension up to a Z51 or firmer suspension, then with the F55 system brought back in play with MRC shocks, would need to have the F55 firmware aftermarket re-flashed to get it correct instead (think at least GS firmware flash, is not more refined instead).
