I thought the TPMS sensors had to be programmed into the computer, or registered. My Autel is suppose to do that but I haven't tried it yet. So yes you need the right sensor, but each sensor must probably have like a Ethernet MAC number to identify it to the computer, so the computer doesn't read some other cars sensor. Maybe they missed one, just go back and try again.

How it works

So the cars antennae sends out a ping to each sensor asking for the data in a low MHz frequency. That wakes up the sensor, if the wheel is not spinning it uses the battery inside, and if spinning uses a accelerometer that generates power. In the ping message is the Id of the sensor so not all the sensors send back a response packet or sequence. Probably just a JSON string of text unencrypted. Then the computer reads the data and updates the display values.

I wouldn't worry about it, visit the shop again and read a magazine.

The tech used the bead breaker on the machine in the wrong place on the tire and broke the sensor. Happens if you are new or not paying attention. Ive broken my own sensors trying to rush the job.

There are new, inexperienced techs anywhere you go. Sometimes you get lucky, sometimes not. Going to a porsche dealer has absolutely nothing to do with it. Probably Every dealer has new techs that havent changed as many tires as ive owned cars. **** happens, let them fix it and move on. Find a place with an excellent, honest tech and stick with your guy. Mine just quit at DT and now im trying to figure out who i can allow to touch my cars again.... feeling violated...

Last Spring I had Discount Tire install (4) Michelin Pilot 4 SUV on my car. They were horrible. They had installed the XL (extra load) version suitable for the battery powered Macan. I pointed out their error and they swapped them out for the standard version. Fantastic tires. In all of this tire on, tire off, no sensors were broken. They did scratch the wheel interior though by roughly scraping off the balancing weights. They paid for a mobile wheel repair service to come to my home and repair the damages. Fine, but still an un-necessary hassle overall.

I get tires at DT for years, for 2 Porsches.
Several years ago I took a photo of the counter display re TPMS.

I have never had an issue with TPMS after DT installed new tires.
(I have had other issues, such as scratching my wheels or trying to sell me new, old stock)

Next time I need new tires, I will get a quote from both DT & Porsche.
DT does offer the Road Hazard warranty.

In your case, I think the tire "tech" screwed up & DT should fix it. Speak to the store manager.

I had an identical problem at Discount Tire in December. DT checked my original sensors with an external tool and determined one sensor had a low battery. They replace the sensor. After driving a few miles, the error message went away.

Good luck

Battery life is given as 5 to 10 years and generally the battery in Porsche (and most) TPMS sensors can’t be replaced. Need new sensors.

My bet is they save about $5 per wheel in not having to make sensors with replaceable batteries. Long as they last past warranty period the accountants are happy.

Pretty much any tire dealer can read the state of the TPMS sensor batteries so worth asking they do so. But I expect sensor replacements during tire changes assuming they have not been replaced in the last 5 years or so.

If one goes dead on you, you know the others will follow. Been there….Done that….

Thanks for your replies guys. I just had DT replace the sensor in question today (drivers side rear). Drove it for about 30 miles or so and reset the system 3-4 times. Still not working. Is it possible that it takes a while for the system to relearn or am I going to need to take the car into my local dealer?

 

[Cavallino]

Typically need to drive the vehicle for around 10-25 minutes at a consistent speed to allow the system to recognize the new tire pressures and recalibrate. Think the at a consistent speed is the key here.

Really? My understanding was that you just had to be above 15mph. I drove it a bunch on the highway and it still didn’t budge.

Had to have all my sensors replaced 2021 GTS (November '20 build). This was under warranty but the way the defect manifested is the system could not be reset using the driver interface whenever I switched from summer rubber to winter rubber and then back. It sounds like you've spent quite a bit of time messing around with this and I would bite the bullet and go to a dealer. Properly operating sensors for me usually register within a minute or two driving around the block.

Yep. I have an appointment for this Thursday at my local dealer.

In case you didn't know already you can get your own TPMS sensors and have DT install them. When I had a failure recently I purchased my own and had them install them (same install price whether you source from them or bring your own). I purchased from here:

thank you for this! $22 for a sensor is dirt cheap and Definitely cheaper than having it diagnosed at the dealer. dont know why I didn’t think of this earlier lol. I’ll give this a try since it looks like DT installed a sensor that‘s different than the others… 🤦‍♂️

Early last year I had my winter tires installed on my newly powdercoated winter wheels at discount tire. If I had to do it again I would highly recommend a good indy or dealership (2nd choice). Discount tire moves hastily and without enough attention to detail. The snapped one of my TPMS sensors but they were honest and let me know. The had me come in the next weel to have the new sensor installed and all was well. Next time, indy euro shop.

at least they told you and took care of it. Did they damage your wheels? I still use indy shops for my 964 and 996. Our Q7 and my Macan (daily drivers) I still go to Americas/Discount Tire since I like to take advantage of the lifetime balance/rotation which I wouldn't really take advantage of on the 911s..

You rotate your Macan tires? Cannot rotate mine (MY 2016 Turbo), different size F vs. R.

You can rotate left to right assuming they are not directional. Most people don’t bother.

I think my Michelins are directional
