W213 - Changing displayed speed to MPH and getting it to stick!

[Rez]

Hello all,

Recently back in the MB fold with a 2017 S213 e220d Premium Plus. great car, a few niggles hae been sorted, one remains and this is where I'm looking to the hive mind for some wisdom as I can't work it out!

The Speed in the digital dsiplay in the instrument cluster keeps defaulting to Kph. Every morning I get in, start the car, select my profile (or any profile for that matter) and the car is by default in Kph. every day I go into the settings, change to Mph and off we go.

If I stop it will sometimes stay in Mph, other times it changes back to Kph. Without fail however, every morning I come to a Kph display.

I'd like to be able to set it to Mph and for this change to stick. I can't workout how to save the setting. every other setting change saves itself to memory but not the units. I've re-done my profile numerous times, each time with the car first in Mph and no effect.

Any guidance is appreciated!

Under EU regs, the car must display both kph and mph.
I don't think you can change this unless it's possible using Star diagnostics at an indy.

We have seen this on a couple of cars, but not looked into it too deeply. It would defiantly annoy me. I will try and find a solution in new year.

Easily done by Star/xentry, Vediamo or DTS Monaco.
If you pop into East London, I can do it for you, payment would be a double expresso.

Thanks all! To be clear it is the central Speed display I am wanting to set to MPH and for it to stay permanently. Really odd that we can't set it permanently without resorting to a STAR hookup.

the law says UK cars must have the ability to display speed units in both MPH and KPH

if the main cluster is set to MPH then the small digital display default is set up to always swap to the opposite, in this case KPH - so it seems its doing exactly what its supposed to do.

in fact as the law never said the proper speedo must show the units on a grown up dial - rather than having both round the edge of the dial, or toggling the main display, many manu now just have KPH on a nasty digital display - the Mini does this naff method

in fact if your left dial is not a screen and its printed out as a MPH unit - if you can't toggle it back to KPH it will be a right nuisance if you drive in the rest of Europe and indeed illegal

£100 quid fine no points I believe

KPH is permanently displayed in the bottom left corner of the central display. It’s reading 0km/h in the picture. The bit he has circled should stay at mph, or kph, whatever it has been set to. For it to keep returning to kph when restarting suggests to me a software glitch, possibly the country setting within the cluster software.

Agreed - although I would never disagree with @Uncle Benz . There is definitely a problem - I use the central mph display and it always stays as mph except on the rare occasions I change it manually (Katie prefers kph if driving my car in France).

good spot - so its the optional other info section, and would normally be the same as the needle - on a BMW they used to have two hidden speedo features you can enable - digital version the main cluster and Sat Nav speed - so an accurate speedo - but if you had only this, it was offensive as was always different to the needle by 2 or so mph
