Should have taken it to your independent or to Porsche from the get-go. If you ordered them at Tire Rack, then sent them to your dealership, it would have cost you $50 per tire AND you would get a free road hazard plan. One number to call; one throat to choke. Now what?

 

Okay? What was the point in this comment? It’s a little too late for “should’ve” lol. Obviously had I known that I wouldn’t have gone to DT in the first place. I’ve learned my lesson.

 

Best bet is to probably take it to a dealer or independent Porsche specialist and have them check. You could try ordering parts, but no telling what the Tires + people did. Might’ve installed the wrong sensors. Not sure there is much you can do on your own. Live and learn. Good luck.

 

I agree with this approach. Either the dealer or a reputable Indy that specialized in P-Cars. They should be able to figure it out.

 

sensors may have gotten damaged, or they could've installed the wrong ones. or the battery may have crapped out.

 

Tires aren't your only expense at the dealer. I bit on a reasonable price and after the tires were off the wheels I was told they wouldn't accept my TPMS units. The Porsche ones they said they had to use were incredibly expensive. I was compromised because of my position at that point. The net result is I will not buy from the dealer again.

 

It is likely DT installed the wrong TPMS sensor. When I had America's Tire replace all four tires recently I was given a short tour of the inner workings of the installation area. I asked about the TPMS sensors and the tech showed me a wall rack full of TPMS sensors. He said each set of sensors were for different car brands. He showed me the ones they use for Porsches based on the frequency of the reader. They also double checked all of the sensors prior to installing the wheels back on the vehicle.

I would suggest that you take the vehicle back to DT and allow them to fix the issue. If they are not willing to or they are unable to then take the car to the dealership and have it fixed. If DT can't fix it and the dealership can and the issue is related to an improper TPMS sensor or something else done by DT then have the dealership print out the cause and solution. Take that to DT and have them reimburse you. As special as Porsches are they are just buying TPMS sensors in bulk from a third-party provider like every other car company and installing them on our cars. Tere is nothing special about a Porsche TPMS sensor. This was evident to me when I saw the rack of sensors at America's Tire. There were only about 10-12 different sensors in the rack, IIRC.

Thanks for the info. I got in touch with them a couple days ago and they said they’d order a new sensor from a warehouse and replace it for me. I’m waiting for them to contact me or i’ll be getting back in touch with them soon to ask about that.

 

Today I took my 2022 Macan S in to discount tire to replace the rear tires. TPMS was working fine prior to taking it in. After I got the car back, one of the sensors didn’t read and shortly after the TPMS light came on and the whole system is not working. Tried resetting the TPMS multiple times to no avail. Went back to the shop, one of the techs opened the tire and showed me the sensor. It was still there and didn’t look damaged or anything.

Did the tech damage a sensor? Should I order a new sensor or have the dealer check first? Car has a little over 19k miles on it.

TPMS sensors can get easily damaged if tire replacement is not done at a Porsche dealer. Wheel repair shop that was refinishing the wheels on our 2016 Macan told me upfront, TMPS sensors may get damaged, so be prepared to get new ones. Just by showing it is there, is not a proper way to prove they did not damage them during tire install.

My advice would be to go to the Porsche dealer and get the problem resolved, most likely damaged sensor and then hold the tire shop accountable to pay for it.

There must be some procedure that dealers use to protect the sensors. I had a flat and had to use the tire sealant (OEM) and I was certain the TPMS sensor will not survive as I had to pump the sealant through and then drive 100 miles back home. However, the sensor was not damaged, reported accurate pressure on the drive back, then the tire replacement was handled at a dealer and I always talk to the techs to understand how they do things and they said, we cleaned everything and TPMS sensor is good as new.

I do agree with others; the dealer now is the cheapest and safest way to get your new tires and get everything done properly.

 

The dealer will definitely be where I swap tires next time. I had no idea that it would be equivalent or even cheaper compared to a tire shop. This way I also won’t have to worry about a tech damaging a TPMS sensor lol

 

It really surprises me that any place would have a wall full of sensors that are car specific. There are several excellent aftermarket sensors that are multifrequency and work with any car. One brand, one part number etc. I use Autel in my Macan's snow tires, they work perfectly.

Tire dealer should fix it

 

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?

 

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..

 

I think my Michelins are directional
