Stunning, stunning cars. A shame if you didn't go further north than Loch Lomond! We holidayed on Skye for a week a couple of weeks ago and the M5 was just remarkable (even on 95 RON - V Power appears to be unavailable past Glasgow).

Yeah I would say its a max of around 1.5mpg better. But its carrying 350kg more while developing approx 35% more power so still a good achievement!
Waiting to see the new M3 rela life figures aswell. That could factor in.

I continue to be amazed how economical this thing is, given the performance.

Pressing on a bit



Not pressing on at all!!



Just before I stopped it was showing 56.1mph, 37.5mpg. That's actually better than the official Extra Urban figure or 37.2. The consumption adjustment figure has been changed so that it's actually pretty accurate compared to a brim to brim calculation, within 0.1 mpg.

Which way did you adjust it, above 1.000 or below 9.000

I messed about with it for quite a while and now I can't remember for sure exactly which way it was!!

I 'think' it's the same way as the E39, which was set at 1050. But I found a post which indicated that it was the opposite, so 950. I tried it both ways and I can't remember which one it was in the end. I'll check it and get back to you.

I took mine to 980 and it was out, so reset it back to 1.000.

What is this MPG correction factor of which you speak?

It's in the hidden cluster menu.

Press and hold the odo reset key, keep it held until the menu pops up.
Short press scrolls through items, long press to select or exit a sub menu.
Go to Lock and enter the sum of the last 5 digits of your VIN.
The Correction Factor is near the end of the menu, item 21 I think.
The base value is 1000, you can adjust it up or down to make the reported MPG more accurate.

Is it April 1st? What else is in this hidden menu & how exactly is it accessed? I've never heard of it.

What's wrong with the preset MPG calculation?

Would love to know how it's possible to get over 30mpg? Best I've had on a long run at 75-80 was just under 29mpg. So hard to stick at that speed as either the inner Schumi in me takes over or i hit ste traffic.

It's not April 1st!

Pretty much all BMWs since at least the E38 have had a hidden cluster menu that lets you monitor various things, battery voltage, fuel levels, coolant temp etc.

The default mpg calculation is almost always optimistic, the Correction Factor allows you to adjust it so that it's more or less accurate.

I've found that the economy takes a long time to level out on a run, the best part of an hour. If you do short journeys, no matter how you drive you'll struggle to do better than the low 20's mpg, low teens for very short or city driving.

Thanks. May have to check that out. Majority of my runs are long distance schleps & short commutes are rare so maybe I should leave mine as is?

How do you access this hidden cluster & any other interesting stuff in there?

Do a couple of brim to brim fills together with OBC resets and see how they compare. In my experience the petrol cars are usually 7-10% optomistic, i.e if it says 33mpg, it's more like 30.

See above. Long press on the Odo reset button get you in, initially the trip counter will reset, then after a couple of seconds it comes back again, after about 10 seconds you get the menu.

Personally and being rather sad I don't trust the OBC and have a app for that smile

It does require strict input which rather sadly I've now done for years over several cars. It's the only real way of determining costs and it's as accurate as you can get.











Probably because I've run my own company for 20 years and like numbers wobble





Or could be I'm still traumatised from my afternoon with Cliff Richard when I was 9 wink

Anyway, as you can see I get nowhere near the mileage some do hehe

I've found my OBC to be reading around 0.3mpg over so I think I'll leave it as is. But thanks for the heads up.
