Sudden Increased Range

[S1PJM]

Hi, I recently bought a 73 Trophy and very happy with it. However, in the past 2 days the 100% charged range has leapt from 230 to nearly 270 and this increased range is maintained as the range goes down ie. showing over 200 range with an 80% charge, driving with heater and headlights etc. Obviously the range cannot miraculously improve so I'm wondering if there's a reset somewhere which will cure the fault.

I don't think you need to worry! I've seen a similar (though not so large) increase in my 22 plate MG5 PFL. The apparent anomaly didn't last long!

If you want to be "sure", after your next charge to 100%, reset the GOM (sorry, can't help with how to do that on the Facelift version) and then see what it says.

It's a hangover from your recent driving (e.g. a lot of downhill and energy recovery). It can go the opposite way too! I never reset on my MG5, as it sorts itself out eventually. I just mentally attuned myself to the fact that 1% battery is roughly equivalent to around 1.8 to 2.2 miles distance, depending on whether it's winter or summer (unless it's been 'floored' on the M-way), and do the mental calculation.

From memory (as I'm still between EVs while my insurance is sorted), with the ignition on, use the steering wheel buttons to navigate to the GOM or range display. Then give a long press on the "OK" button on the RHS of the steering wheel until the display resets.

Your recent driving style and it might have done a balance charge if you left it on overnight?

If you haven't reset the trip counter it may be an indicator of how badly the previous owner drove it

What sort of driving are you doing? If you are around town at slow speeds it could very well be telling you the correct numbers. If you drive at 70mph for a while I expect it will change dramatically.

I get this on the MG4 - the GOM resets after 99hrs driving time and regains its original optimism in the process. Not sure we’ve actually done enough in the 5 yet for comparison but would expect it’s similar.

Thanks for the responses. In the past few days I've driven on all types of roads/traffic including motorway driving and charged to 100% last night. This morning 100% was showing as 276 miles but a 39 mile drive at 3.2 m/kwh reduced this to 79% with a 193 mile range left. So basically the range change (83 miles) was double the actual use and the percentage change points to an actual range of 200 miles approx rather than the 276 approx shown before today's journeys. Given the weather/light that's about what I expect, it's not a huge issue as I'll just use the % as a more accurate guide, just slightly annoying!

Are you sure it's not flipped itself to km?

Think your self Lucky , I've got to drive home 26 miles with only 35 miles on guess o meeter as some numpty forgot to charge last weekend

9 miles plus the normal few they don't talk about is pretty safe.
Sounds like a normal day for me.

Had this a couple of times.....it's when the cumulative range is reset, I think I created it myself on one occasion by a reset of the infotainment system. On another occasion I had it happen with the cumulative total clocking over 9999.

That makes sense...wondered what the trigger was!

My 72 FL has just done this. Did the tesla update yesterday which reset the cumulative statistics. Was showing 305miles from 100%. Only done 30miles or so since then but already down to 280mile at 100%. Hopefully it'll settle down soon.

Isn't 280 plus 30, 310.if its accurate as the guessometer is fickle you've only lost 5 miles

This will go up and down depending on the weather use of heating eg. So do not worry about this, I did a long journey in my car and if you watch the range against the sat nav when you got you destination set up you find it’s very good ( in my car it was).
I was able to work out I would have 5 miles left and below 10% when I got home.
