BMW and M Power Owners

You will be very impressed
I've got them on the back already.. frustratingly they have about 4.5mm left but one has a puncture that's already been fixed twice and is losing 3/4psi every couple of days so something has to be done.

So I'm taking the opportunity to do them all since the fronts (Michelin P4S on when I bought it) are getting lowish and I wouldn't change just one side of the backs at once.
 
That's always the issue with xdrive & changing out odd tyres
It's nothing to do with xdrive for me, I always change in LR pairs and I was always going to have a 4x set when the time came.

I'm just miffed I've got 4-5mm left on the rears but one is basically dead.
 
Conti's never last as long, as other brands do from my experience. They're great tyres, but not very durable.. I think my current favourite is GoodYear from more premium brands and Uniroyal for budget s...boxes. Michelin seems to have dropped in quality...

Just got to work... the 440i decided that today is the day that the battery warning comes up and tells me to start the engine...
Eh.. I gtg to work hahaha.

Here's hoping it will start after work and I can get it charging over night.

Are you driving with stop-start enabled?
 
Is this actually true? I've seen mixed opinions on it.

Unlikely - just a vocal minority on the internet that have had to replace batteries (or alternators/starters etc) and instantly blame it on start/stop, despite the fact that there's no way of proving/disproving that it wasn't just normal failure.

The original battery on my Start/Stop equipped Mini had managed 12 years - that's no worse than any of my previous non-stop/start equipped cars had managed.

Things wear out from being used.

If we look at 2 components which get used during ignition the most:

- Starter motor
- Battery


So if you consider that the more you use something, the quicker it wears, then I’d say it’s safe to say that yes, it does wear the components more quickly. Consider whether other (more expensive) components are going to wear first though too.



That being said, I don’t know of anyone that has worn a starter motor on a modern car with stop start. Batteries degrade themselves anyway, and I haven’t seen any evidence of them wearing more/less quickly other than people just saying it has worn their battery.



Additionally, I believe it takes 2 or so seconds for it to be worth the trade off of the extra consumption of fuel during start up to break even.


Tl;dr

Use it if you like it, don’t if you don’t.

And are all designed to cope with the additional wear and tear versus non-stop start components
BMW didn’t change anything in the S65 in 2011. So the main chain tensioner is argued to be too strong when fully tensioned on a warm engine when it stops and starts…

They did stick a AGM battery in though but still better to turn it off or code it out (free with a GTS gearbox map)

Stop start is purely for the NEDC of that era and I’d argue still has more issues in component life with it on than off. But brah.

I’ve just set up my M1 and M2 buttons to turn off Stop/Start and drive round in M1 during normal use

It's the opposite, cars are engineered to fail after X amount of miles/time, they only have to survive the warranty period.
You would be surprised how little development is done in the automotive world if things don't need changing :P
R&D costs money meaning less revenue, no business will go for that.

Yep, ecology is ruining cars and is affecting the reliability.. ehh
