So the TPMS which is OEM MB I purchased in November 2023 when I swapped on my 20" AMG Wheels the passenger rear TPMS has been giving me error saying there 18PSI then 22PSI then would go to 33PSI etc meanwhile its always at 40PSI

I bought another OEM TPMS this week and swapped it out and reset the TPMS and its still giving me the error and the dash TPMS so looks like the original one I bought in november was fine the whole time.

My issue is.. what the hell is wrong then?

I don't really have much more info than that lol, - 2 OEM TPMS both saying the same thing and i've reset and added 40PSI back in the car.

Strange, have you tried swapping the wheels from D/S to P/S and vice versa?

That I didn't do swapping - After I left the tire shop i drove off and noticed it still doing it after I reset the TPMS - its luckily a small stupid issue but who wants to drive everyday and have the TPMS light on the dash and then prompted to the screen showing you 18PSI or so when you don't.


Wonder if Peter could do something if I don't solve this

I was just on the W221 forum - I saw 315MHZ is the for US models and 433MHZ is for Euro Models.. I have 433MHZ - Does the 315MHZ carry over onto the W222? - but my 3 other sensors are perfectly fine
