I hope this helps to decipher the DTC's codes you may get,

Is there a similar acronym list for COMAND? None of the acronyms in the enclosed screen shot are in the list above. If not, can someone explain the acronyms? (HU=Head Unit, TV=TV and Navi=SatNav is clear)

Desperately need to know the part number

:wallbash:My apology if I am asking this question in the wrong place. It is my second posting & still can't find the "sticky post in the new members" but I am hoping that you forgive this. I desperately need to know the part numbers for xenon control unit & ignitor for CLK200K elegance 2003 (WDB209342) with HID factory fitted. Also if you know the Bosch OEM equivalent part number. Many thanks
 
Just a small point
ADS = Adaptive Damping System (not "Automatic")
 
Help 911!!!

Need help with nfinding out the reset stereo code after replaceing battery and cant locate manual, someone help?
:wallbash:
 
how do i unlock stereo???2000 mercedes UT (new battery)...lost here
 
The nearest dealer will help...proof of ownership will be required.
 
Can i ask a question about a a190 bas asp problem?
