Hi

my actual range isnt correct displayed.

my tank is filled for 1\2 full and only showing a range of 84km left instead of +- 300km . Is there a way to reset this and let it calculate again ? The last few weeks I didn’t fill my tank to 100% but i guess this can’t be the issue..

Any one knows how its recalculate again ?

i already removed the fuse of the instrument cluster number 208 and removed the battery for 20minutes but after reinstall the battery it still gives the last saved range so it doesn’t reset either.

 

The range is purely a guesstimate based on your most recent driving. I don't know exactly how far back it looks, but it's somewhere between 20-50 miles of driving and your average consumption over those miles. If you've recently been driving in a high consumption manner, then the predicated range will drop until it sees your consumption going down.

 

Hi, the picture says 84km range left this is converted from km to miles 54 this must be about minimal of 186miles left.=300kmh

my last 130kmh of driving averange consumption was 10L/100km

so my car must say 300km left instead of 84kmh

60L petroltank 1/2 filled = 30 litres full inside

 

I would recommend you fill the tank up and make a note of how many km the car has so far. Then drive around until you have about 1/4 tank left and note how many kms you have driven on 3/4 and fill up. Take the amount of fuel it takes to fill the tank again and calculate the actual average consumption yourself using the amount of fuel burned and the kms driven to see if they match what the board computer says. I would expect the range to adjust as you drive. It won't go negative. Your actual manually calculated consumption will tell you if there's perhaps an issue with your engine.

 

I understood the Estimated Range was calculated on a rolling average based on previous 15 minutes of driving = (Distance/Fuel-Used) x 4

 

Your range is totally dependent on your driving style, so those numbers are kind of fictive. Only time it's useful is when you are on a long journey on the highway, then it might be fairly reliable.

Since I hate to visit the gas station I have learnt exactly how many liters are left when the fuel warning light comes up, then I learnt when the fuel light stops flashing (= no more gas left) I can still go around 20 km more (MB C220 Diesel) ... my wife HATES that behaviour from me LOL

 

That's pretty much what it comes down to. In the EV world, the range predictor is often referred to as the GOM (Guess-O-Meter). It's really no different for an ICE. The remaining range is largely a guess especially if the tank still has a substantial amount of fuel left. It tends to become more accurate and more relevant the emptier the tank gets and with steady driving. During most of my driving I don't look at the remaining range at all. It's not even something that I regularly have up in my instrument cluster. I tend to fill up when my tank is down to about 1/4. At least in a petrol car it's not a good idea to let the tank get too low and have the engine suck in sediments. I'll bring it up on a road trip in order to time my gas station stops. In the FL with the digital instrument cluster it has a very useful view that shows the remaining miles to one's destination if navigation is active, side-by-side with the remaining range in a nice bar graph, so I can instantly see if I have enough fuel to reach my destination or if I need to make a pit stop.

 

Did jou manage to solve this issue anyhow?
I have same problem
