Had a nice surprise this morning, got in and drove the car .3 miles and the TPMS cleared and is now reading all tire pressures. So very happy and thank you all for the information of waiting and resetting, it worked!

Purchased a set 18" Macan Take off wheels and tires with original TPMS intact. The TPMS system does not detect the sensors on the newly installed wheels. The local independent tire shop tells me they need to break down the tire and wheel set that came new on the car and extract the those TPMS sensors and re install in the 18 inch wheels because they claim the sensors are vehicle matched. I am not buying it. Any input appreciated.

TPMS sensors are not vehicle matched. No such thing. The sensors on new set may be defective. Did you do a TPMS reset?

 

[jzwu]

LOL. How do you vehicle match a new set of sensors when replacing the old ones? Stay far away from that shop.

Shop said they tried it.Doing reset myself now.

Agreed. Sounded like utter nonsense to me as well.

Does the Macan really have some TPMS valves in some market? In Switzerland, we don't, it just compares the wheel rotation speeds with the current car speed to estimate the pressure (one must drive above 25km/h or 15mph). Maybe less accurate, yet it works well enough.
There's even an alert when I swap summer/winter wheels as it detects the rotation speeds are suddenly completely off; and I'm to set the wheel size and kind of tire in the MFD (TPM/tire type). See

So one would only have to drive at a stable speed above 15mph for a couple minutes.

After I swap wheels (I have a Summer set and an All-Season set for the Winter), in the TPMS menu, I have to change the wheel size & type of tire (Summer, Winter, All Season....pg. 182 in the owners manual), check the vehicle load (either Full Load, Partial Load), then I have to drive it a bit for the new TPMS to be "taught-in" until the tire pressure warning light goes out.

Now with that said, if the TPMS in your take-off set have dead batteries, or they are the wrong type (incorrect frequency, they need to be 433MHz), the Macan's PCM will not detect them. Don't sweat it though if you need a new set of TPMS, you can buy a set of German made HUF TPMS for about $149 w/free shipping on ebay, with either black or silver stems....

Agree with the first paragraph above. Needs to be configured in the TPMS menu, and then drive for a while to "learn"

Learning now.

Duplicate 🤷‍♂️

I’m having a similar issue, put on new wheels and I am not seeing a pressure reading for any one of the wheels. I went to a local shop that used a tpms tool to check every wheel. It seems like one of my wheels has an issue where the tpms is not putting out a signal. I have a new set of 4 tpms units at home, but I may try to change just one first.

TPMS Low Tire Warning

I had the same issue - after driving thru a heavy rain storm, the TPMS warning came on saying my right rear tire was 4 lbs too low. I did check the tires and one was low, but I could not get the warning indicator to go out. Finally, read here about the reset of the TPMS by changing the tire size and load - and then back. Started the car and drove 2 miles and the indicator went out. Thanks all.

I owe you a shot!!! I was totally freaking out about the warning symbols! And, nothing wrong with my tire or pressure. If you're ever in S. Denver:🥃🥃

I did for my last set of Winters because they were not any more expensive than outside or even Costco's pricing.

I'm not for my new set of summers that I need very soon because Porsche refuses to get Michelin Pilot Sport 4 S tires for me.

In case you are not aware the PS4S is not the same tyre as the PS4 that many people are so positive about.

Is that even possible? I know you have to drive above 15mph same with my Macan which definetly has wheel sensors but how would wheel rotation determine tire pressure?

I was wrong. That's the first car where I need to drive at 25kmph/15mph to get a reading of the pressure, so I thought it was a system comparing the number of wheel turns vs a speed computed from the GPS. But the owner's manual does say:

Changing a wheel and replacing tyres

• New wheels must be fitted with radio transmitters for Tyre Pressure Monitoring.
  Before tyres are changed, the battery charge condition of the wheel transmitters should be checked.

So I'm guessing the "learning the wheel" is to find which wheel sensor is in which corner of the car.

Here’s an update...
I took off the repaired winter tire and put the summer wheel and guess what?...after a little bit of driving I had readings in all 4 wheels.
I took off the summer wheel and put the winter back on and guess what? I do not get any readings on any of the 4 wheels.
Sounds crazy how one defective sensor affects the whole TPMS system....now I’m confused but at least I know who to blame when they repaired my flat.

Based on other threads here this is a common problem. My guess is that it is software rather than hardware. A similar event happened with me, OE sensors with second set of tires, had a flat, took it off the car to get fixed and put it back on a day later, then no readings on all four wheels. Here's what fixed it.

Engine running while stopped, go to the tire selection menu and change what type of tires that you have. Use the same diameter, just AS to summer or whatever. Then drive off and the system will reset itself and you should get new pressure readings. Once that happens, switch back to your correct tires then drive off again.

The second time I did it with the correct tire setting it didn't read the pressure, so I reset with a different set of tires a second time, let the system read it, then switched back again to my correct setting and it finally "took".

Same thing happened to me after an underinflation alarm. After inflation, the system didn't reset to normal. Alarm persisted. I was able to reset by going to the tire settings, switched from part load to full load and back and the system came back to normal without the alarm.

Couldn’t find any reference to this question:

Just bought 21” Pierelli Scorpion Zero Plus A/S tires for my 2016 Porsche Macan S. Went into the TPMS settings to reset. There is no option for a 21” A/S tire. So should I choose a 21” Summer tire setting, or a 20” A/S setting?

I have read here that if you can take the car to a person dealer/indi that has a piwis tester tool that they can add this to your TPMS settings in the MFD.
