Any BMW mechanics??? (CANBUS CODES)

[Roadrunner]

My 23supra MT was is a accident in November.
It has been fully restored for about 2 months now but the collision place cannot Pinpoint the CANBUS codes the vehicle is throwing. They have literally checked and replaced many things and are running low on options.

does anyone know someone that can help with pinpoint or figuring out what is causing those canbus codes?

From what I have read and some logical deduction it seems most likely that either a section of the wiring or a connector has been damaged during the repair process. CANBUS errors in BMW's have been linked to wiring harness crimped joints in some locations. An oscilloscope used in conjunction with a wiring shake test can be used to give a clue to the location. Not an easy thing to track down. So logic dictates a very close examination of all the wiring and connectors that were in any way affected by accident or the repair process looking for crushed or pulled sections of loom and connectors or loose individual wiring terminals.
