2004 XJR upper wishbones front
 

I've been searching the forums for an answer and maybe I've overlooked it. I need to replace the upper control arms on my 04 XJR. I know I need to remove, or at least drop the air shock to get the a-arm bolts out. If I unplug the air line and the electrical connection at the top of the shock, will that set a code that requires the $200 Jaguar reset and calibrate routine? Doesn't look like there's enough room to lower the shocks with wires and air lines attached. Just wondering if this a job I can do, or might I just as well take it in and let the Jag store do it? Already have the a-arms thanks to a post referencing justjagsuk.com.

Thanks,
Dale
