Interesting related thread on the ZPost Forum about difficulties some owners are having finding anyone to do four-wheel alignment, especially following installation of aftermarket suspension like H&R coil-overs: http://www.zpost.com/forums/showthread.php?t=672836
According to this thread, many independent shops are refusing to do any alignment work on zeds saying they don't have the extra machine/computer to reset/rezero the steering angle sensor. They're saying only BMW dealers have the equipment necessary to do correct alignments. Meanwhile, BMW dealers are refusing to align cars with aftermarket suspension like H&R coil-overs 'cause they say they can't match OEM specs and they won't align to any other specs.
What experiences have folks on this forum had with this? I think this question is still on topic since erol_h (and I) will soon need to have our cars aligned following installation of H&R coil-overs.

when i spoke to the local garage for a price to install and sort out the alignment they did mention no issues at all even though they didn't install my suspension im still going there to get the alignment sorted.

I believe the key to avoiding problems with the Steering Angle Sensor during an alignment is to always keep the front toe adjustment even from side to side by only adjusting both tie rods equally. Also, keeping the rear toe as even as possible so that the steering is not offset due to a non-zero thrust angle should help, too.

I always use a spirit level on the spokes of my steering wheel to make sure it doesn't move when I'm doing an alignment, to keep it absolutely centred relative to the toe. So far with several camber and toe changes, i haven't had a problem with my SAS.
