There are a couple different frequencies for TPMS sensors, and they even have different types of communications, so I would verify that what you have on the tires is 100% compatible with the G01 X3. Can also use a TPMS diagnostic tool to read the sensors directly and make sure they are working right.

2019 M40i, delivered 9/20/2018 with 4 miles on the odometer
19" wheels with Bridgestone Alenzas (245/50R19 all around)
TPMS malfunction at 800 miles.

Dealer confirmed a sensor was bad and ordered new one. Scheduled to have it installed next Friday, 26 Oct.

Appears that there may be a bad batch of sensors installed on our X3s.

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!

I'm seeing the exact same thing, hanging at 19% however I had my wheels/tires put on at Simply Tire.

Any luck getting this to go away?

You guys need to order oem sensors, generic off the shelf aftermarket ones won’t work. My local tire shop has tried to install them on another X3 and they will not sync properly even though they were the same frequency.

I got the oem part number from my dealership and found a place on eBay that sells them much cheaper than the dealership. Bmw wanted $200 CAD per sensor and I got a set of 4 for only $160 CAD shipped.
It took two weeks to arrive from Slavokia but they work perfectly.

I haven't investigated further, but read somewhere that decent tire shops got tools to adjust the sensors for each brand. I.e. as long as the sensors work on the correct frequency, it should be possible to fix.

I've ordered from a third party, saying what make and model I need them for, and got an "ok no problem". Haven't tested yet though.

There are tools that can read the ID code off each BMW sensor and transfer it to the aftermarket sensor so that there is no need for the vehicle to relearn new sensors, and you can swap tires seasonally with no hiccups. Autel is one of the brands that makes sensors and tools.

TPM malfunction with 80 miles on the car. X3 sDrive. Great job BMW....

[skier219]

It's interesting to me that I can go weeks without any malfunctions and then get one or two a couple days apart, then go weeks again with no malfunctions.

I really think it's got to be a glitch in the software perhaps when there is some sort of interference with the signal and the algorithm doesn't handle it well. Last two I got were about 3-4 weeks ago and I ignored them and the system reset itself within a couple minutes while I was driving. That doesn't strike me as a hardware or sensor failure.

Has a solution been found for this? Is it a bad batch of sensors as was suggested by Abaer?

I picked up my 2019 X3 M40i last Friday (built around the 5th of October 2018) and had this error driving home with 15-miles on the clock. I reset the TPMS and was fine over the weekend, then it threw an error again today with 130-miles on the clock.

I've got the tyres correctly selected to 21" summer tyres (Pirelli PZero's).

I had the same issue with my new snow tires. They were getting stuck around 49% then faulting out.

Problem was my tires were filled high as per the manual for speeds >100mph. Apparently the sensors don't like the pressures to be high when syncing for the first time.

By simply lowering the pressures to 33/38psi, the problem was solved. You can increase pressure after syncing if so desired.

I don't think it's bad sensors, at least not in my case. It is behaving more like a software glitch. I probably had 5-6 malfunctions in the first couple weeks, then went 2-3 weeks with no problems, then a couple malfunctions, then 2-3 weeks no problems, etc, but now it's been a good 5-6 weeks with no issues. If it was bad sensors I think the failures would be more often, based on all the research I did.

[Arcanum-UK]

After repeated TPMS failures in the last month, often with the inability to reboot past 49%, I took the car in to the BMW dealer. Generally my experience with the BMW dealer is so painful I live with minor issues in a car for the entire time I own it rather than want to bang my head repeatedly against a wall from trying to get them to fix something under warranty. And I don't mean stuff like rattles which are hard to locate... and I'm intrigued that the X3 rattles more than my M2, M235i and M135i ever did.

Anyway, I digressed, this time the service department were shockingly helpful and quickly resolved the issue over two while-you-wait appointments.

Turns out that there was a faulty TPMS sensor. It was on the receive side, not the TPMS sensor in the car. They replaced it under warranty and I've driven 50-miles since then with no failures.

Weirdly the recommended pressure shown in iDrive increased from 2.2/2.4 bar (front/rear) to 2.3/2.5 bar after the work.

[kmualim]

My X3 M40i also had a TPM malfunction yesterday.
No mods to the wheels and tires; they are the 21” from the factory.

So went ahead to perform the “tire reset” and the TPM malfunction was resolved. There’s no more “notification” for the TPM malfuntion anymore.

Hopefully it will stay this way. If not, dealership will be my next option since the car is still fairly new (4000 miles).

Put new wheels / tires on yesterday. I have the correct 433mhz TPMS sensors installed. Set tires to the 20" version in iDrive and take off. Never gets above 19% reset. I'm going to the dealer today for something else - hoping they will fix it, or shed light on why.

I know you set the tires to 20" but you also did a RESET too, correct?

Correct. I tried to do the reset through iDrive and it keeps getting caught at 19%. Dealer wants $100 to diagnose since they aren't OEM sensors (BS I think), but I'm going to take them to Discount Tire - where I bought the tires and see if they can figure out if one of them is faulty or if it's the iDrive reset system. I've swapped out tires and rims on probably 10 vehicles. In the last several years any of them with TPMS you pretty much get in and drive, and as long as they are the same frequency as the OEMs the things just work. Not sure what's going on with this system.

[Alias1431]

Just a shot in the dark, but are you parked next to your other set of tires, where the proximity could be affecting the read from the other sensors? Or perhaps another vehicle that could interfere? (I don't know anything about this stuff)

[Tronner]

So I just did some research and the HUF UVS4040 sensors that Discount put in my wheels are an OEM sensor, however they do require calibration to the vehicle. The HUF RDE077V21 is also a 433mhz sensor that will auto calibrate. If they had put those in, then the TPMS reset SHOULD work. It looks like Discount Tire or the dealership should be able to calibrate mine to the vehicle with their tool.

I thought about that as well, but only for a few seconds, then I drove around for probably 30 minutes and still stuck at 19%. See my reply above which should identify the reason.

I went with the Schraders (OEM) from Rock Auto for a winter set-up. Worked fine. Summers put on a couple days ago... No problem at all with the switch.

[spta97]

I just had this issue with my F97 with 1150 miles. I had winter wheels on since January with the OEM tire sensors from TireRack and no issues, and I recently put the OEM wheels back on.

After putting on 200 miles, I got this failure for the first time.

I’ve got my break in service on Friday so I’ll report back what they say.
