Hello. I changed out the front SAM on my "new to me" 2009 C300 due to a faulty headlight. The donor vehicle was built 1 month earlier and same options but SAM was a different part number. Everything works great now but I am getting the red warning TPMS INACTIVE. I don't recall if this was on with the old SAM but don't believe so. Both Vin numbers have the same option code 470 (low level tpms monitoring) as well. I hooked up a scanner and have the 1644 code (incorrect variant coding) present. Any idea on how I can fix this or delete TPMS all together? Maybe i need to drive it? Thank you in advance. My Best.

You CAN NOT swap a sam and majority of modules with coding them to your car
coding does not match
It's like trying to win Powerball
