CCC Bootloader failure. Searching correct ZUSB

BMW FQ · 08-28-2020, 11:20 AM

Hello everyone,

since this is my first post i'm not sure if this is the correct category but i hope.

Since i bought my car the CCC was only working if the car was there for at least 5 hours else the CCC was rebooting till it stands again for hours. I tried to repair it with the CCC Repair CD but it didn't worked. It even made it worse because now it doesn't even start and have the BMW Logo on the Display. HUD and PDC and all the signal sounds still work but it scks without Display and Radio.

I tried to flash it via ISTA/P and it couldn't read the VO and the manual import didn't work either.
Second try was to flash it via ICOM over WinKFP with ZUSB from a Forum because it didn't show one on Inpa. Didn't worked -> Wrong ZUSB. Hopefully somebody here can help me with this and give me a hint or the correct ZUSB which i am missing.

I have a working when pulled CCC unit here if you're interested. It's just sitting in my basement parts hoard.

but honestly I would urge you to consider doing the cic swap.
It's worth it.

the bootloader error basically means that it's recognized that it's programming is borked, and it's awaiting a new flash.
at least that's my understanding.

Thank you for your offer, but since this is just a software error which could be solved with the correct i chose to try to repair it. I also thought about the CIC but since the CCC have a less value by selling this way i'd rather want to just repair it.
