I work for Mercerdes currently.

My dealer just bought a 2012 7 with 95kish miles that was prev diag'd buy local BMW dealer needing a valve body. I have replaced valve bodies in the E65/66 cars (while I was working for the BMW dealer) as well as multiple MB cars.

Is there anything I need to know before I dive in and replaced this valve body? I can get it coded/programmed, that's not an issue. TIA for any help.
