Tom,
Did they come with the screw?

It looks like they also carry the sensor for the 2022-2024 models. Alcar S7A102 for 79,90 EUR approx. $87+shipping

 

No screw Jim. I purchased those from Max BMW. They do state on the website information about the necessary screw for reference.

They did mention to me the availability of the Alcar in the event I did not want to wait for the Schrader.

 

I bought 2 of those sensors from my local KTM dealer. They had them in stock. I also purchased the screw from my local BMW dealer.

 

Hello there,
I did exactly the same thing.
Been 6 months now , they work like a charm.

 

I ordered a couple cheapies off AliExpress, they look identical. I think they were under $20 each.

Unfortunately I HAD to replace the tires before the sensors arrived so they're just sitting here on my desk.

If anybody wants to try them out, I'll send them to you if you promise to report back on the results. Otherwise they'll just standby til my next tire change.

I threw my new old style sensors in the garbage a few weeks ago. After having 2 fail within the year I bought 2 of the new sensors. One is installed and the other waiting for its new tire.

I decided to take a risk by ordering these from Germany several weeks ago. The total cost, with shipping for two OEM sensors was just at $150 US. At the time I ordered them they were listed on back order with an availability date in mid June (I don’t remember the exact date). I confirmed via a WhatsApp customer service chat some additional information and felt comfortable enough to pull the trigger and order two. As the mid June date approached I received an email that the date was now being pushed to mid July. Of course I became slightly concerned but in that email it was stated a complete refund would be issued if I wanted that. I reached back out on the WhatsApp chat and was reassured of all the information contained in the email. I decided to stick it out.

On or about July 1, another email was sent stating the items were now being received and would be shipped in a day or so. This was a couple weeks earlier than expected. The sensors in fact shipped on July 2, and I received them today (USPS via DHL, required a signature).

I wanted to go with OEM sensors but was not going to pay the inflated price. Obviously these have not been installed but I suspect there will be no problems.

I give this company an A+ when it comes to customer service. They were always on top of the issues in short order. Of course it helped that I was in no rush to get these sensors.

If your interested in OEM sensors at less than half the cost, this could be an avenue.

@Thomas et al...I just ordered two of the same from same place. I may have mentioned that I had previously ordered one (plus a 80deg. valve stem) last year when I built up the K1300 wheel for the darkside experiment, and I had zero issues with this company at that time. This time all-in $150.09 USD...so looks like the exchange rate has been steady!
I started getting a few funky readouts (actually just ---) from my rear OEM wheel sensor several months ago, and then on the TTD trip both of them (F & R) were flaky...so I figure they are dying. The OEM sensors on my bike were added in June 2017 and are obviously older than that, so >8 years for TPMS sensors to last!? Probably above average. If I have nothing but --- consistently prior to a tire change I may pull tires to swap TPMSs anyway.
On another note - this store did not have the screw in stock, which is probably good since I may well have bought two of them for 5.95 Euro each...which is stupid for a small cap screw that never gets seen. I'll be able to find what I need locally.

 

Aren’t those screws hollow? With a little blue loctite you can use them ovet.

 

@flyergc , @Arizona Jim is correct. the torx head bolt holding the TPMS sensor in the wheel is hollow and made of aluminum. There is a sealing compound added to the bolt. Reusing old bolt is no problem; you don't need to reapply the compound.

Copy. My other thought is…my wheel has the valve stem in the spoke; so the TPMS is only bolted/screwed to the inside of the wheel (drop center). Why does the bolt need to be hollow at all? The air doesn’t need to come thru it to fill the tire, right? If so, any cap screw of the correct thread and head size would suffice.

 

The air DOES need to pass through the Al TPMS retaining bolt.

 

BMW uses a hollow bolt to save weight, lol.

 

OK. Since I haven’t removed the original sensors yet, I will take your word for it…and maybe post some photos later.

 

Here is a photo of a stock K1600 wheel showing the rim side of the hollow spoke. They thread the hole, to which the TPMS sensor is attached via the hollow Al bolt. You might see residue of the mild thread locker the BMW factory used on the TPMS attaching bolt. If you threaded a solid bolt into that hole, air would no longer pass from the valve stem into the rim/tire cavity. That is the only hole in the rim.

 

@flyergc , we aren't saying we "think" the bolt is hollow to allow air from the valve to reach the wheel/rim. We are saying it because we "know" the bolt is hollow...

Duane

 

OK. Observed. Got it. It is what it is.
