TPMS Malfunction Message

Neo1130 · 07-30-2019, 05:02 PM

Hey guys. 2019 X4 M40i has been throwing this message at us since we got it in November last year... Pretty random and the TPMS light will illuminate and stay on for a few days. Of course, we make an appointment at the dealer after about the 30th time it goes off and they kept for half a week and the light of course didn't come on for them nor were there any stored codes... I saw someone else that had this issue on their X3 but I cannot find the thread again. NONE of the sensors will read which leads me to believe it's the car side of the system that has failed. Tires of course are all up above where the light trip is so it's not low pressure. All tires have a "--" when trying to read.

Now the dealer will get corporate involved and I dunno what will happen if they can't figure it out. We just got out of a lemon which this car replaced (2018 Hellcat) and don't want to do that process ever again. I don't believe it will come to that but I just want to know what the fix is going to be for those few that had this same problem...

Could be a low battery on one of the TPMS sensors, have they checked this already?

My 5'er showed this code ... of course it was already 7+ years old, but the fix was replacing the batteries in the TPMS.

If that's the issue here, I would hope it would be covered under warranty on an 2018 or 2019.

I've already had one replaced. I was turning into the dealers parking lot to look at another car when the same message appeared on the screen. They confirmed it and scheduled to replace the sensor.

A month or so after that I've had the message come and go for the last month. Haven't had time to get it to the dealer yet. Since the light started coming on it keeps showing a low tire despite the pressure being correct. Definitely seems to be a problem somewhere in the system.

I had the same problem and reset my tire settings in Idrive. The error came and went at least two times a week but hasn't resurfaced since making the settings changes.

I just went to the dealer to get a sensor replaced today. Hope it’s fixed.

In April we had very similar issue with under 1K miles. Dealer identified a faulty unit and replaced the one on the driver side front wheel.

Two weeks ago we got a new variation of the previous faulty TPMS warning while driving on the interstate. This one said something about the TPMS has been disabled because something was interfering with signal/information, and it also said to check tire pressure manually. I did & they were fine.

Dealer could not find a cause with their diagnostics and escalated to their internal resources while keeping the car a couple days & providing a loaner.

All said and done the consult recommended replacing the unit in all wheels. Its been a little over a week with this fix and so far so good.

Time will tell. On the bright said, the rest of our baby still works...

Best of luck - hope this helps.
