Two weeks ago my E65 2002 was fine, all communication with INPA, ISTA aso working. But the center display sometimes flickered or went completely blank. I bought a replacement on eBay, same part # 6 921 572. Installed it, but still flickering. As it didn't have access to comfort suspension or PDC, I decided against wasting time trying to code it and reinstalled my old display.
After messing with the car, I always check for errors with ISTA+ and delete them. This time about 2/3 of my modules were gone and the rest was a mess of weird names and red errors. I checked with INPA and same issue. The communication with the car seems to stop/crash.
I was under the impression that it might be the LM module that acted up, because it always failed to read and it holds the VO, so I decided to flash it with the VO of the CAS module, but suddenly the CAS module could no longer be read either.
Thinking maybe my K+DCAN USB cable was bad, I took out my CARLY Wifi adapter and tried using my iPhone. Still a lot of missing modules, including the LM. But for some reason Carly was able to read the LM settings for coding?
The car works 100% perfect when driving. It is only when trying to communicate outside the car, that I have problems.
So the pc can't be at fault, since the same problem appears on the wifi adapter. The soft on my pc is fine, because the iPhone has the same problem reading the car. The car runs just fine, all modules doing their job. So I guess something needs a reset, a sync?
