One for the more technically minded.

Apart from recent issues not connecting to my phone (Google Pixel 3) but connecting to both wife's Pixel 2 and an old iPhone the Command unit has shown no issues or errors in everyday operation. I seem to have fixed the issue connecting to my phone by deleting both mine and wife's phone and repairing only mine.

What's thoughts on these error codes & should I be concerned about the second code - B238A00 - Fan 2 of the control unit has a malfunction?

I still have a few weeks of warranty remaining under the Mercedes-Benz Approved Used scheme.

Well if one if the fans isn't working then the unit might overheat.

Unless there's a WIS document that says that this error message can be ignored, the dealer will have to supply a new HU under warranty.

That said, I don't think that the potential overheating issue is related to the non-workind Pixel 3 connection.
 
Just noticed the fan failure is a stored code - have you trued erasing it?

Also, is your NTG4.5 unit using the latest firmware?
 
Many thanks for your response, much appreciated.

I cant see how to access the firmware version of the Command unit - any ideas how to do this?

The Star report was generated on recent service so I don't know if the code was erased or not.

Looking at the code more closely (for the fan error) can I check that I've read this correctly - used to work around IT so pays to ask the obvious...

  • The error first occurred at 76,736Km
  • Last occurrence was at 84,486Km
  • In total the error has been reported 68 times
  • Number of ignition/command switch on cycles since last occurrence (10) seems self explanatory - I've switched the Command unit on 10 times since the fault was last reported.
