Updating/Replacing CCC Unit

[Greggo]

I am curious why the shop is telling you to replace the CCC unit? After the previous 'non fixes,' not sure I would trust them with anything electronic, or opinions of same.

Also sounds to me as they do not bother to troubleshoot anything. "Update your FRM!." Always, always look for the simple answer first. How hard was it to actually look at the lock and find the broken plastic?

Did this shop do any sort of module programming or updating? Did you do any updating besides the FRM? Did this shop program the new FRM?

You need to find a local member with programing tools and skills. At the very least, find a new shop.

The AUX selection should be a simple check of the CCC programming. Not much to that, nothing external would cause that issue. If they were messing around the rear hatch, might have disturbed the camera or connection. Nobody was trying to program something in the CCC?

Best of luck.

This has all been primarily phone conversations up to this point, and to be honest I don't have the best understanding of the different modules and coding. From what I recall, they started with updating/programing the original FRM after they pulled some fault codes and ran electrical tests on the 3rd brake light, and saw that there hadn't been any updates since the original production. They said there was a chance the updates could crash the FRM and require a full replacement, but after those tests seemed sure it was the reason the 3rd brake light wasn't working, and why the hatch would not always soft close. I had looked around the hatch to see if I could find anything that stood out as loose/broken that was causing the close issue, but didn't find anything so something electronic seemed plausible.

When they ran the updates, the FRM did crash and so they replaced it with a new unit. I don't know if they did other updates at that time, but they said they did have charges of coding from BMW.

They are now saying the CCC unit has failed and also needs to be replaced. The options are either a new unit ($2k+) or find a similarly configured used CCC to try to replace the current one ($500-600).

I'm obviously pretty upset because had they just found the plastic issue, I wouldn't have paid for the diagnosing/coding/replacement FRM, and then received my car back in worse condition than they had received it.

The shop said they took a CC from a loaner vehicle, and confirmed that the CCC was the issue, but also said the loaner CCC didn't have all the same options and so that is why they need to find a used one from a similar spec'd X5.

I have no clue how to do any coding, or how to find someone local who knows how to do that type of coding. But my main concern is just having the audio, rearview camera, and parking sensors work as they originally did.

Is it possible that an experienced coder could restore those features without having to replace the CCC? Or is CCC failure that can't be remedied by coding a possibility?
