2024 GLC43 complains about tpms
Hello all,
Just installed my winter tires (from older glc43) with sensors and now the system is complaining that it can't read the tires sensors , are they incompatible ? The winter tire wheel sensors are 3 yrs old .
Any ideas on if anything can be done to force to connect or should I just replace them?
I hear maybe the batteries or just incompatible
What a pain
Thanks

Did you reset TPMS under the Service|Tires menu? They don't just magically pair. Once you reset the system it should detect the new sensors and store the new reference values.

Is this in the main screen on console mbux?

Tried a couple of times to reset values since I changed tires and then it said monitor restarted followed by missing sensors .Will drive for a bit and see if it eventually detects them.
But I'm not optimistic
Unless we can see with OBD what the issue is ?

No, I believe you need a TPMS scan tool. Not entirely sure what's involved. I've only really come across situations where new sensors were bought and they were learned automatically by the car. It does take a somewhat specific procedure of driving above a certain speed for a set amount of time. Might be easiest if you stop by a tire shop. They can probably sort it out for you.

Thank you all for the replies and advice much appreciated

So I had them reprogrammed and the toms picked up the wheels winter sensors after some highway driveway. I'm worried that the toms picked up the summer tire sensors piled up the car backseat ?
Is that possible ?

I suppose that is technically possible, but TPMS sensors these days contain an accelerometer that picks up rolling motion and the sensors only start sending a signal once the sensors detect that the wheels are rolling. This is why you generally have to drive a few blocks before the tire pressure shows up in the instrument cluster. However, I don't know how specifically the accelerometers are tuned to pick up rolling motion vs motion in general. I don't know if the general motion of the car is enough to wake up the sensors of the summer wheels in the back of the car for them to start sending a signal. The other part of this is that there's an antenna in each wheel well to pick up the signal for the sensor. It also measures signal strength and it uses that to determine which sensor is at which corner of the car in order to display the respective tire pressure for the correct tire. So there's a form a signal triangulation going on to assign the correct signal to each of the wheels. Your tires in the back of the car are essentially located outside of where the antennas are looking for a signal. You will know soon enough if it picked up the correct sensors once you unloaded your summer tires.

. Will see soon.
