It's not the average speed because it goes up and down immediately then when I stop it shows 0mph. As indicated in my pic, 38kph is nearly 60mph. When the analogue shows 100 (on my private race track) the digital is showing 62.
I was doing 60. I've only had the car a few weeks so I'm not sure if it's had another cluster. BMW's I know have a tamper dot that appears on the display if they're messed with, do merc's?
Anyway, it doesn't really matter, just curious really.
I think your first thoughts are quite correct the digital readout is showing the MPH equivalent of a KPH analogue figure. My SL shows MPH on the analogue speedo and KPH on the digital which I find very irritating I would much rather it showed MPH on both. A trip to the dealers is need I fear!
It's like the digi dial thinks I'm doing 40mph so tells the analogue dial to show 60kph which I wasn't, I was definitely doing 60mph. The digi should really have been showing close to 100 as the analogue dial doesn't show kph as well as mph which every uk car I've ever driven does.
Mind you, the way this thing accelerates I sometimes wonder if the speedo is actually in kph! [emoji48]
It is a minor niggle tbh and certainly not something I would like to be financially bummed by the dealer to correct [emoji57]
Isn't 38mph just over 61kph? If so, it looks like the analogue is reading under, assuming digital is more accurate?
I have to admit I thought speedometers were allowed a small margin of error but only to over-estimate the actual speed, not to underestimate it, presumably because otherwise you could be caught speeding when you thought you were driving at or below the limit?
I didn't think you could change what the analogue units where, only the digital - unless there is something in the engineering menu. Do you have an option to change the digital units in your normal menus?
