BMW HU ENTRY (CHAMP 2) iDrive Repair

The following symptoms may not need a CCC iDrive repair.

• Slow navigation menu: the CCC iDrive is slow (has a lag) in executing user commands
• Intermittent sound
• The CCC headunit randomly freezes and the iDrive controller / the joystick spins freely
• The CCC iDrive resets a few times, but then starts and works properly
• BMW logo stuck on the screen, CCC reboots a couple of times and then it’s stuck on the BMW logo again

Other possible causes:

• The CCC has trouble reading the CD / DVD. Remove all disks and test again. If a disk does not come out by itself, please do not force it out (as this may cause mechanical damage).
• Another module connected to the fiber optics ring is faulty and prevents the proper functioning of the CCC iDrive. The most common other causes: the bluetooth module (MULF or MULF 2) and the sound amplifier (TOP-HIFI, also known as Logic 7).

Troubleshooting other possibles causes:

• First, check whether your car comes with the bluetooth and / or sound amplifier modules that are known to be prone to failure. Enter the last 7 characters of your VIN number here or here and check if the list shown on the website includes:
  • 644 Preparation f mobile phone w Bluetooth – this is the MULF or MULF 2
  • 677 HIFI System Professional – the TOP HIFI (also known as Logic 7) sound amplifier
• If you need to, read this article to understand the BMW VIN (chassis number).
• Next, remove the module identified on the first step in one of the following two ways:
  • replace the above with a known to be functional module (from a friend, a local service etcetera)
  • remove the suspect unit and use a MOST bypass loop connector to close back the optical fiber loop. This is mandatory. If you simply unplug a module and do not close the optical fiber ring, unexpected results will follow.
