TPMS - Unique to the car or not.
Posted: Mon May 09, 2022 9:07 pm
My 2017 Macan SD came with a very nice set of Gen 2 20" Turbo alloys. Over half worn, but still legal.
The ride was quite harsh and I decided to downsize prior to a road trip to the Scottish Highlands. I came across a set of 18" Macan alloys online with nearly new Michelin Cross Climate tyres.
Yes, I am well aware that they are not Porsche approved, but I was already an advocate for these fantastic tyres, both summer and winter use. Had them on a previous car and even stuck a full set on my son's car the week he passed his driving test.
Firstly, the tyres really suit the car and were fantastic on hundreds of miles of minor and single track roads in Scotland.
But, regarding the wheel/tyre change, I have followed the forum advice and changed wheel sizes on the dash then tried to let the car reset the tpms system.
Having tried to reset the system dozens of times over more than 1000 miles, it constantly tells me I need a tpms service.
So, the car is 5 years old, out of warranty and I'm reluctant to visit the main dealer unless I have to.
Tried a tyre depot and the manager informs me the tpms sensors need to be removed from the 20" wheels and fitted to the 18" items as they are specific to my car.
Asked if an independent Porsche technician can reset the 2nd hand set and he guessed they may be able to be recoded.
I'm not so sure this info is correct.
I promise, I have searched the previous posts so as not to waste your collective time, but can find nothing to help.
So, do I need new sensors? Or is this a software issue?
Main dealer or one of the two local Porsche Independent technicians?
