E63 tpms stuck on reset
Some time ago I replaced one tpms sensor which was not functional. It would display the tire pressure on 3 of 4 tires. When I replaced the one sensor the display showed all four tires for about two weeks. After which it began to display the message in the video below. After a reset it will show the same message. The display will never change, even after more than an hour of highway driving. I've searched and searched and can't seem to find anything, hoping someone already knows how to fix it. Thanks.

I have noticed, that when car has been out of service for a month or so, the TPMS can take 1-2 days to wake up, just keep resetting it.
When I first installed new sensors it took 3 days for it to start working.
FWIW 2 weeks sitting takes less than a day to start working and aprox 30 mi.

I've been resetting and messing with it for over a month. Last weekend I drove from Houston to Dallas dicking with it the whole way. I read something about pulling the fuse for the TPMS system but I can't seem to locate where this fuse is. I do have SDS and no TPMS related codes or errors.

Correction on my previous statement, what I was looking at were the values at the time of activation. Every time I would reset it on the cluster it would record the tire pressure and temperature from each sensor.
Anyway, it's been resolved now.
It looks like it was operating as low line tpms system even though the option for mid line was selected, out of frustration I went through all the other choices, two of which turn the tpms feature off, well when I selected mid line again I flipped to the tire pressure screen and there they were... Not sure why it suddenly started working, it was already set to midline. Anyway, thanks for ze help.

I have a 2010 C63 and I am having the same issue. The message Tire Pressure Monitor Active is showing instead of the normal 4 digits on each corner. I tried resetting it a few times earlier but still doesnt go back to the 4 tire pressure # screen.
How did yours go back to normal? Mine was working just fine a few days ago and all of a sudden this morning it showed this message.

I swapped out a set of OEM wheels on mine and now don't have the TPMS sensors in the wheels. I am lazy trying to get different things done to the car so have not researched where to buy TPMS sensors and go get them on the car. IS there anyway to pull a fuse (where is it) to get that stupid light off my dash. Driving me nuts and the notice in the info screen every 10 miles or so.
