TPMS - converting from KPA to PSI

[Freakuk]

Mrs Freak has a Merc GLA (24 plate) and it really grates me that every now and again you'll get a tyre pressure warning but it's always in KPA, does anyone know how to change this so it displays PSI for the life me I cannot find a way.

Mrs Freak panics like crazy as she suddenly thinks a loss of 10KPA is suddenly life threatening and I have to keep telling her it's not much more than 1 PSI and wouldn't make any difference.

Not the same model, but for the display between speedo and tacho (think Service / Tyres), I don't think KPA can be changed.
However, on Mercedes Me (mobile phone) you can choose either KPA or PSI.

Eighteen months ago, I knew nothing about interior car tech. Got to grips with most of it now.
Our previous Mercedes (no tech.) was in use for 24 years. Still works perfectly, but has now joined my collection.
Wonder if my new M-B, with so much technology, can last as long?

May be someone with the appropriate diagnostic kit can change it to PSI? One assumes they display it in PSI for the States.

MBito will do it on most models - you have to buy the dongle and each change you make on the app costs so it's not cheap but it does work. I did it on my E-class and changed a few other little things while I was at it.

It can be done, I have done it myself on my 2021 E class, but you need diagnostic software, then its just a case of delving into the module and changing the option.

I have Launch, it was about 120quid. It's a bit slow with loading through screens / menus etc but does the job eventually
