2019 X3 TPM Malfunctions

skier219 · 08-30-2018, 09:26 AM

In another thread, I mentioned TPM malfunctions on my newly delivered 2019 M40i and several other folks commented they had the same problem. So let's start a new thread where we can maybe collect reports. Give your model (x30i, s30i, or M40i) and wheel/tire size, along with basic info about how often you see malfunctions and how far apart, etc. Feel free to add any other details/conversation you think is relevant or helpful.

skier219 · 08-30-2018, 09:32 AM

I'll go first:

M40i, delivered 8/17/2018
21" wheels with Bridgestone Alenzas
First TPM malfunction happened at about 85 miles. They reoccur every 50-100 miles.

If I attempt to reset after the problem happens, it either fails right away or gets to 46-49% and stalls, then fails. If I try again before my next trip, after the car has been shut down, everything resets fine in a few minutes with steady progress on up through 100% as it completes.

Side note: my M40i had chromed plastic valve stem caps with "N2" stickers, I assume these were added by the dealer and they must have aired up the tires with N2. I replaced these with regular plastic caps to see if it makes a difference. Metallic caps can interfere with TPMS signals, although I wouldn't expect a problem with chromed plastic, so I am doubtful this is the problem. But I am mentioning N2 and chromed caps as possible factors.

And one side note. When doing a TPM reset, BMW puts a progress counter that runs from 0-100%. We have no idea what this correlates to, if anything, but during the process the car is attempting to take the four signals from the tire sensors and assign them to each corner of the car. It does this while driving, through a combination of methods that allow it to sleuth out which signal is coming from which tire. This is known as an automatic relearn procedure.

Seems to climb in percentage much faster if you go around lots of corners rather than just getting on the highway. I guess it uses the ABS sensors to correlate wheel speed and can match that up with the TPM sensors to some degree.

I noticed that too. The TPM sensors do use a simple accelerometer to turn on when the wheel starts rotating and I am sure that can be used to learn rotation direction and correlate with wheel speed data from the ABS sensors. There's a lot if interesting information here:

2019 M40i, delivered 8/28/2018 with 6 miles on the odometer
19" wheels with Bridgestone Alenzas (245/50R19 all around)
First TPM malfunction happened before I drove off the lot. The salesman told me something like, "Don't worry, it needs to learn the tires. We see this all the time"

The TPM warning happened 3 or 4 more times in the first 80 miles that I drove the vehicle. I found an option buried deep in the options menu related to TPM settings. The option was configured for "select" tires. I changed the setting to 245/50R19, then the system asked me to drive about 1 mile during which time it calibrated the TPM. It stalled at 99% progress, but eventually it finished.

As of today, I have driven the vehicle about 700 miles, and I haven't had any more TPM errors since I changed the tire size setting about 600 miles ago.

NS324 · 09-04-2018, 08:13 PM

2019 M40i with 19" wheels & Bridgestone Alenza 001 RFT 245/50R19.

Didn't occur until about 150 miles.

As per thestuarts, the identified tires were set to "other" and to winter/all seasons.

I updated the type to summer, along with 19" wheels and the 245/50 tires.

Have only driven about 5 miles since the reset, so cannot yet tell if the update will have a lasting effect.

HollyM · 09-04-2018, 08:42 PM

Gang,

I am taking delivery of my M40i this Friday at the Performance Center. Can someone please provide the "path" to which I can find the TPM options setting? Bear in mind I've not owned a BMW with navigation/software, so please provide clear path so that I can update my settings to the tires on my vehicle. We are taking three days to meander home, and if I saw the TPMS warning for days on end, I would be concerned driving every mile. Thanks in advance!

skier219 · 09-04-2018, 09:08 PM

It's under vehicle status. However, if you do see the error, you will get a message with a link to take you directly to tire settings.

Ffluke · 09-06-2018, 06:04 PM

“System may be unable to detect tire pressure loss”. My 2018 X3 M40i with 21 inch wheels and 16 miles had this error within days. It would appear, then reset. When I took it to the dealer, there wasn’t any record of the 6 occurrences in the OBD2.
I’m still getting the error, but I just went nto the tire settings per a previous post and will see if that helps.

Day Laborer · 09-07-2018, 03:57 PM

Happened twice since first 1200 miles. Before the malfunctions, I had already set up the correct tire sizes in the iDrive. M40i, 19s all-seasons. Went away after a few miles of driving.

skier219 · 10-03-2018, 01:59 PM

So I went a good 3-4 weeks without any TPM malfunction errors, but got one a couple days ago. I ignored it since I was driving in traffic and didn't want to take my eyes off the road, and within 5 or 10 minutes, the warning light went out and TPM was back to functioning. Previously I would have had to stop the vehicle, do a reset, and then drive off while it went through the motions to get up to 100% (sometimes it would fail).

Is BMW pushing over the air software updates? I don't think so but I am wondering. I'd almost suspect there had been a software update sometime in the last few weeks that reduced the TPM malfunctions and/or let the car reset itself. It's sure behaving differently than before for me.

IM_ALL_IN · 10-03-2018, 04:02 PM

Vehicle delivered last weekend and we've had 2 malfunctions since. One at about 30 miles and the other around 100. I reset it both times and it hasn't came back on yet after another 300 miles.

19' X3M40i
20" Alenza with N2

NS324 · 10-03-2018, 06:18 PM

My first occurrence was at about 150 miles. The second was at about 315 miles, with the 3rd occurring about 20 miles later.

What I found after the 2nd & 3rd occurrences was that I needed to wait until the tires were "cold" before attempting to do the reset. Without cold tires, the reset failed over and over again.

Same for me -- when it would fail, I couldn't reset most of the time, but if I waited until the next morning it would reset right away.

TPM Malfunction just triggered for the 1st time since delivery. Driven about 700 miles since delivery. I am going to give it a dy or two before I reset it. Lande departure system also automaticall deactivated when the TPMS warning triggered.

RegieX · 10-03-2018, 10:56 PM

what I notice is that all of you have M40i although the wheel sizes vary from 19" to 21".

being on this forum gives me M40i envy sometimes.

Go FasTA · 10-05-2018, 08:52 AM

I began experiencing this problem in my '19 M40i yesterday morning on the way to work. I have the 718M (21") wheels and had less than 300 miles on the odometer. 24 hours later and after at least 6 attempts I have been unable to fully reset the TPM. Mine will hang at either 46% or 49% complete and then give me another warning about TPM failure. Has anyone found a way around this yet?

skier219 · 10-05-2018, 06:57 PM

I saw the same failures at 46 and 49% when the problem first started happening back in August. Lately I have been ignoring the TPM malfunctions and it seems to reset itself.

I was able to reset it by choosing Summer tire / 19inch wheel option. I was not able to reset it with the winter/all season tire setting even though my vehicle has the 19inch all season wheel.

TPSM malfunction again! Will reset tomorrow AM at cold start. If it happens again, I am leaning towards taking it in for a dealer check.

msav9999 · 10-13-2018, 09:12 PM

Hi,

I just bought some winter tires (with TPMS) from Kal Tire.

I tried to reset the pressure sensors to calibrate with the new tires. It initially begins to calibrate, the calibrating/resetting percentage makes it up to 19%, stays there for a period of time, then I get a message saying "TPMS Malfunction".

I've tried resetting and driving several times but the same thing always happens, 19%, then a malfunction message.

Any ideas what's happening?

Does BMW use specific "only BMW can provide" TPMS sensors? Is there some type of different reset I need to do?

Any help is much appreciated!
