Range display issues

[SueFR]

Hey,

not sure why this happens or if anyone has had it before.
this is second time it has happened to me, the range display isn’t showing correctly. Iv just filled up and it’s only showing 300, usually shows 550-600

last time it happened it corrected its self on the next fill up.
Anyone had this or know why it happens?

Thanks

sounds like a sender unit problem

Yeah I got told that before but this is only second time it’s ever happened and like I say first time eventually corrected its self.

What happens to the fuel gauge when it faults ?

 

[Rusty2k]

I doubt there is anything wrong at all.

The range is calculated on short term fuel consumption and fuel level not long term. So if you have gone through a patch of bad fuel consumption immediately before filling up (flooring it, town driving, crawling in a traffic tam or sitting idling, etc.) then that is what the range will be based on after you've filled up. Parking on a hill will produce the same effect as the tank has a float sensor for the level.

If either of those are the case you should see the range increasing as you return to your normal driving pattern.

As you've only experienced it twice in the space of a year I suspect you are just seeing quirks from how the range is calculated rather than evidence of a problem.

I never said a time scale? But yes that’s what I noticed last time eventually it started going up again but did take for another car fill up for it to take full affect.

thank you

My fuel gauge is fine it’s the computer range that is the issue

No, but you mentioned you'd been told it might be a sender issue the last time it happened so I searched for posts that you'd used the word 'range' in before to and found your previous thread from Sep '21 and read through that... I was rounding up from 11 months to a year!

Hahaha check you out. Mr detective!

 

[Rusty2k]

Haha to be fair I searched back through my own posts too as I knew I'd answered this before but couldn't remember who had asked it...

Turns out it was someone else a couple of years ago..

Miles to empty low

Hi everyone hope your all sane with the lock down but I’ve got a problem with my miles to empty on my MDF today I’ve absolutely brim it to the top and it’s only showing 425 mile range now I’ve filled up many times before to the brim and got way in to the 600 range any ideas what could cost a 200...

I know it's a bit necroposty, but I was looking at my MFD the other day because average mpg seemed weird...long story short...

Maybe you hit the ok button on the steering wheel.

You can change the way the MFD shows mpg and when it resets range amongst other things.

My mk2 has 2 memories for AVG mpg, and 2 methods of resetting range.
The MK3 has 3 methods of resetting range, on fill up, manually and after many 1000s of miles.

Resetting the short or long range trip computer settings does not affect the range calculation on the Mk2 Leon.

What was it?

First time it happened it corrected its self after filling up again but second time it happened last year it’s taken a lot of steady driving to get it to what it was and I believe it only messed up as I had some work done on my car and something must have been affected in having work done? Anyway it’s now back to how it should be
