TPMS fault

[davidgrist]

I have an MG5 long range. Recently the TPMS system registered a failure. There was no pre-warning. MG said it would be the tyre pressures. I wasn't so sure.

£105 later they said they'd cleared the fault codes and inflated the tyres- minimally.

This has failed twice more in quick succession. MG now agree its a failure of the system and not about tyre pressures.

There is a system receiver embedded in the centre console which monitors the signals from the sensors. They think this has failed.
3rd attempt is now booked.

Anyone else had this failure? Car isn't yet 2 years old.

The TPMS cannot possibly fail as a result of tyre pressure other than perhaps if the tyres were grossly overinflated i.e. beyond the range of the sensor. Did you challenge being charged for what should be warranty work?

 

[davidgrist]

Absolutely. This next work will be under the warranty, and I will challenge the previous invoice. Thanks.

I woke up this morning to the TPMS saying one tyre had dropped to 1.0 bar. Checkid it & it was 2.1 bar. Drove to work, it dropped to 0.6 bar, tyre looks fine!

Any ideas?

Just had this fault on my MG5 Trophy (facelift), all tyres showing as unreadable. Worried to drive it. But have to for work. I’ve checked the pressures and all are fine. I drove over cobbled streets yesterday I’m wondering if something has come loose or something? Nearest MG garage is 5 hour round trip

No need to worry then..

TPMS data is transmitted wirelessly, if all 4 are not readable it’s probably an issue with the control unit.

You could check the fuse F32 (no easy access):

Maybe easier to disconnect 12Vaux for a minute.

Yes, I'd try a reboot of the 12V system first.

Yes
My tyre pressure is perfect and all sensors are blank. It's a MG 5 EV facelift. Will be on to MG in the morning

I managed to get this fixed but the garage said it was a bit of a nightmare to do, had to replace the control unit I think, but they had to take the whole front of the dash apart to do so. Replaced for free thankfully. However I have slight vibration noise from the dash when driving as it has been loosened now.
