No one's found a way to get the pressures to display in either psi or bar.

 

You can do it in the app but not in Mbux :smile:

 

Mine was in psi and changed on its own to Kpa

 

You can change units in the Mercedes Me app.

 

Without sounding stupid, can't you just take bar and divide by 100 to get it in bar

 

just found that, yes, 400 kpa is equal to 4 bar. Thanks

 

On the app, at the homescreen, click the profile button (top-right) then click Units of measurement.


You can change them there.

 

Leave it on KPA. A lot more accurate.

 

Just change to psi in your car’s units of measurement settings

 

how do you set the tyre pressure on thge dash to psi and not kpa?

 

You can’t.
Without 3rd party coding.

You can set it to read PSI in the Me app however.

 

TBH I’ve left mine on kpa and set up my pump in the same way so I don’t really know what the psi is

 

I'm happy with it in PSi on the MMe app. I rarely check it in the car itself.

 

Now I’ve got the app up and running I’m using it too

 

Whats wrong with using proper SI units for pressure

caveat - the app isn’t “Live” ie if you look at tyre pressures at night, it reports the pressures at the last time the ignition was on.

 

Absolutely nothing wrong with SI units but I’d still rather talk about mpg than litres/100 km or whatever the equivalent is and probably prefer gallons at the pumps 😂 but that’s just showing my age

 

I have found the MB air pump is as good as any forecourt airline and I have been using that mostly.
