My overhead console for most of the '02 C320's life has always made a slight humming sound. I used a meter and notice there was a slight battery drain (not really that much compared to my seat control model malfunction!), it got worse in the winter months when I left it parked for 10 to 14 days with a rough start. Disconnecting the overhead console dropped the drain down to nearly nothing, except for normal CAN bus activity.

Anyways, My car currently has MB Part A203 820 1401 / 7D43 for the overhead console control unit.

However, according to EPC (MB), the updated part is A203 820 62 01 / 7D43

So to clarify:

A203 820 14 01 / 7D43 (Unknown date)
A203 820 62 01 / 7D43 (A 2004 part) (According to the sticker)

The ES2 codes are the same.

Will that part work, since MB is reporting it's an updated part?

 

Off course the part will work!
