INACCURATE FUEL GUAGE READING - LR SENDER WIRING MOD?

inaccurate fuel guage reading - lr sender wiring mod?

hi...

2011 5l sc currently in with dealer having the wiring modification done to fix inaccurate reading, so a question please to those who own the same.

when filled to the brim, what does the trip computer tell you the mileage range is - mine before going in for work to be done showed ~338miles is that in-line with others?

many thanks!
(though best to start new post..)

the trip computer also takes into account of the previous average mpg, ie, if you have only been doing town driving with low mpg it will take that into its calculations...if all at 50mph with better mpg ,it then takes that into account.. ... - .- -.

Thanks and yes understand it's dynamic. Why I'm asking, with now mod allegedly now done the car now shows ~305 full range mileage reading when full to the brim prior to the work being done it was ~338, so to get worse makes no sense to me.

This mod is meant to correct corrosion to the connector block that affects resistance and thus could send an incorrect reading. I told them to swap out the sender as all under warranty but wanted to know what fellows owners could share regarding fuel tank ranges when full on their 5L SC cars? Doing quick math, ~23 gallon tank, assume say 15mpg = 345miles so perplexing at best to listen to dealer logic.

A few searches on generic sites... Any others have a view pls?

Can't scroll through the trip computer display options and get the present MPG? that way you could work out what it should be on a full tank ie. MPG x 23 = range!! Yesterday I couldn't spell Engineer... Today I are one!

I think tank range on the dash is just a guess. You're better to test its accuracy for 3 tanks. Just reset your trip each time you fill. Try to fill to brim and fill up as empty as you dare. I just filled my 4,4 diesel with estimated 12 miles to empty and it took 90 litres. And what is empty anyway? 10litres remaining? 5? 0?

Whistle they will always err on the side of caution... you'd be a bit miffed with your shiny new Range Rover if it said it's going to run out of fuel, cough and die instantly Shocked They tend to build in a safety factor... it's up to you how far you push the envelope Thumbs Up Yesterday I couldn't spell Engineer...

JZ probably the best explanation it that the reading before the fix was inaccurate therefore giving you optimistic range estimates.

As I mentioned above ^^ do three full to empty tests resetting your trip each time and then you'll know what your actual range is.

Make a note each time of the distance to empty reading too.

Post up the results too.

Whistle Has it occured to you that some lead footed mechanic might have taken your ffrr for a spin? It would only take a few traffic light races and your average consumption will have gone down... this will effect the "Fuel Range" as it looks at how the car has been driven, as well as what it's doing at the present. I would strongly urge you to do a full reset on the trip computer and see what happens.

There is another thing to bare in mind... the garage might have done a reset... and you haven't driven it over 30 (being optimistic as you say you live in London, some parts you're luck to get over 3 mph!!), if you have never reset the the computer then it will be taking all the historic readings as well, and it might have spent years cruising on motorways.. which would give it a high reading on the average MPG and directly effect the fuel range.
