Plot twist:

Mrs Brett just called me to say the 45e wouldn't release the fuel filler for her...

Will see what develops when she brings it home.
Nothing wrong with it....opens fine when operated correctly hehe
Could it be a repeat of what happened before? She pulled up at petrol station and the car wouldn't release the flap because it needed to vent/equalise pressures and then it's taking a needlessly long time to do it.

I grant you the possibility that she was just prodding the wrong button or attempting to open the flap from outside the car without having pressed anything to release it! hehe

She forgot the flap was one where you have to push it in first to release the catch hehe

Could you please stop posting details of anything negative about the X5 45e?
One of these was on my shortlist as a replacement for my E class and this thread had made me look at them in a positive light. If you start posting negative ownership experiences then I will have to go and look for something else. wink

I may well be heading in to Bristol in the week for work, so if you are about you can have a look in person and get really put off of it? biggrin

Just driven my X5 40e from London to Cannes. Got to the petrol station about 450miles in and the petrol flap wouldn't open. After a bit of a google it turns out that after extended engine use the tank needs to vent before it will unlock itself. Well this took 45minutes which isn't ideal in the middle of a road trip - doesn't make for swift stops and progress ! I assume it must be to prevent any sparks from the battery as this process is limited to hybrid models ?
On the 45e there is a fuel release button, you press that and then wait for a message on the screen to tell you the cap can be released. Longest I have had to wait is about 30seconds though.

Is it the same system on the 40e?

In the manual it warns it "may take several minutes under certain conditions"...not 45mins though!
Sorry for delayed response.

Yup so in 4+ years and 20k+ miles of having the 40e this is the first time it has happened to me and it definitely seems to be related to the length of time you're using the petrol engine. As this was my first properly long trip in the X5 this is the first time I had experienced this.

The manual says it may take a few minutes but this was 45mins for the first time and then 30mins for the 2nd time - I had been doing 3-4hr stints though. Usually when I'm in the UK and doing short journeys the petrol cap releases in a matter of seconds as per Brett above. It definitely wasn't ideal waiting at the side of a motorway petrol station for this undetermined amount of time before we could fill up and get back on our way.

On the 40e (and I think the 30e) the petrol cap release button is by the footwell and definitely an after-thought as I am sure the regular petrol and diesel models don't have a release button so looks like it was just added in for these PHEV models.

Overall, it is a minor pain but just thought I'd pass on the info as I was scratching my head with it for a bit until I googled it and saw it was a common issue with the BMW PHEVs.

If I remember I will RFM later and see if there is a manual override... that amount of time is just daft! (Quite often you can move a boot panel and pull a manual release - that's what I will look for)

^^ there is a manual over-ride. There is a green cord accessed from the side panel in the boot that you can pull (hard) that then opens the flap.

I tested my petrol flap in a quiet spot earlier and when pressing the interior petrol flap release button I can hear it venting gas for a couple of seconds before allowing the flap to open.

I don't hear anything out of mine, well nothing obvious.

Due to lock down I've not had a reason to do a long run in it yet - but will have a play next time I'm out in it for more than an hour to see what it does...

Just collected it back from the dealer, from the description it's basically had a reboot and a big software/firmware update.

Just got back from my France trip in my 40e. Stats aren't toooo bad.

2100 miles
48h
24.8mpg
44.2mph

I think the mpg isn't bad considering it had 4x people and 3x suitcases in it for the most part. I think it suffers at the 85-95 leptons mark because its only got a small 2l 4cyl engine which does about 2200-2500 rpm at those speeds which means its working quite hard. I imagine the newer 45e does better at that speed on a long run because it is a 6cyl ?

Some interesting numbers there!
I think you are right, the 40e is much more town/short run focused than the 45e. The XC90-T8 and RR/RRS400e have the same 4cyl setup and suffer in a similar way.
On longer runs without a charge, driving at normal (hehe) speeds I still get high 30's to low 40's - over a much longer run I would expect it to drop a little.

For reference, a couple of years ago we went 4 up in my dads Rx400h to Neunen and back, and got over 30mpg average - at similar speeds. (That was with four big blokes, luggage and a stationary engine in the boot!)

Due to CV19 I haven't done my usual 1000mile round trip to Scotland and back in it yet, but that will be the true test.

Out of interest, how big is the tank in the 40e?

hah well decent story with that. I ran out of fuel on the way back (I risked it as was bored of the previously mentioned wait for the tank to vent) - engine shut off to protect itself and I coasted the last 1/2 mile home down-hill.

It is meant to have a 90litre tank but I could only get 85litres in it after that which makes me think that the car shut the engine off very conservatively as I've long suspected the fuel gauge isn't super accurate and errs on the side of caution so people don't run out of fuel.

That's a slightly larger tank than the 45e then...

I've just ordered a 45e to replace my XC90 T8. I've enjoyed the Volvo it's got everything I need and lots I don't. Seats are great as a I have a severe back injury. Crazy low BIK and 6 pot swayed to the BMW. The Volvo is quick enough and handles ok for a huge heavy SUV in sport mode which lowers and stiffen the air suspension however you must either live in central London or be crazy to buy one of these personally.

24mpg average for Volvo and small tank means lots of fill ups.

Doesn't tow as well as my wife's diesel outlander either. However as an overall package and low BIK there is no other option than these hybrids. Personally I'd take a 6 or 8 pot diesel any day of the week and I think the legislation needs to change as there is zero incentive for company cars drivers to plug in which completely defeats the object and is more harmful for the environment.

Looking forward to trying the BMW when it finally arrives with a 6 month waiting list...

24mpg was all it could manage once the battery was depleted? Was that an early T8, or one of the facelifted ones?

Yes mate 24mpg is the moving average - I never plug it in as fuel is 'free' my electricity isn't...my E350 cdi estate used to do 36mpg. i doubt a RRS SVR would drink much more. It's 2019 MY.

Utter madness not plugging it in IMO, why bother with a hybrid at all?
