Hello

I have replaced my infotainment unit after the factory one failed.

In tyres settings it only has a winter tyres option and no tyre pressure reset, as the old failed unit had.

I have OBD11 2 and guess coding may fix this. The vehicle the unit came from may not have had TPMS installed or activated so I need to figure out how to turn it on.

The TPMS in the Fabia works through the ABS system so there are no pressure sensors installed in the tyre valves.

Pressing the Car button on the unit and going to tyres gets me stuck at this screen with Starting on the side and the spinning loading icon.

Thank you for any help with solving this.

It's adjustable in adaptations, check channels (I used VCDS so with ODB Eleven look for similar wording):

ENG122229-ENG117704-Car_Function_List_BAP_Gen2-tire_pressure_system_0x07 => activated

ENG122229-ENG117705-Car_Function_List_BAP_Gen2-tire_pressure_system_0x07_msg_bus => Suspension data bus

I haven't had any luck with this but guess that the tire selection may be wrong for a start.

My Fabia is Monte Carlo version with 17" wheels and if the unit came from a vehicle with different tyres surely this will not work.

On trying to change the tyre selection the codes are not being accepted, do it will not change. There are only 3 options and the vehicle has 3 tyres in the air pressure settings on the fuel flap so these settings may relate to those 3 different tyre sizes.

You might be better asking OBDeleven (if that's what you are using) or OBDeleven users, it seems, I don't know, sometimes what's supposed to be 'coded' doesn't, the manufacturer has blogs and a Users forum or there's a 'VCDS & Diagnostics' forum on this site with some OBDeleven threads, posts and information.

I know you had it before and it's annoying you can't get it back but on my wife's 2015 Fabia the ABS system is very tardy at reporting an issue with tyre pressure, perhaps if you have a pressure loss to the rear it might advise the driver if they've not already noticed.

An inexpensive, or more expensive if you like, tyre pressure gauge, and usual driver's maintenance (separate and different to VW "maintenance schedule" work) will be better than the Fabia system (on my wife's car anyway which was factory set with factory wheels and tyre size).
