Not great news for the E91
Wife driving home today, apparently battery light came on and steering v heavy. Just about got it back home into the drive. (She also mentioned a whirring sound!?)
Am assuming alternator fail.
How far can you drive with a fully charged battery and non functioning alternator?

Not very; could it be a belt that's slipped/snapped?!Wife driving home today, apparently battery light came on and steering v heavy. Just about got it back home into the drive. (She also mentioned a whirring sound!?)

I'd want to check under the bonnet before starting/driving the car personally!

Isn't the alternator relatively easy to change (well compared to say the waterpump)?Wife driving home today, apparently battery light came on and steering v heavy. Just about got it back home into the drive. (She also mentioned a whirring sound!?)

Has it slipped off or has it snapped?
It seems to have torn longitudinally!Court_S said:
Whoops….hopefully nothing has been ingested.
On cursory glance appears ok.I've taken the airbox off to get a better view.
I released the tension to try and get the belt off, but it's caught behind the tensioner.
And also caught down here:
Getting dark so left it for the night. I THINK I have the tensioner, idler pully and belt (as well as waterpump actually) in the garage for N52 as I was planning to get it done on the 630i at some point.
EDIT: Found them:
What would cause such a belt failure? Presumably one of the spinning components has failed/seized? The idler pully seems fine, as does the waterpump and alternator. I can't spin the tensioner as that bit of belt stuck behind.

Could be a weak tensioner / wobbly idler wheel walked the belt off. I'd change the tensioner and belt then watch it with the engine running, be obvious if something else is amiss.
That's the plan. Will get on it tomorrow morning and see what's what.(Am trying to channel my inner Sreten )

Old belts fail. It looks to have been leaked on too for a while which tends to hasten demise. Good news that you’ve got the new bits in stock. I've taken the airbox off to get a better view.

Maybe not completely related to E9x but a tenuous link (but not worth a new thread), I saw these wheels fitted to an M135i which made it look fantastic, am I right in thinking these are 18” E92 M3 wheels?
Those are BMW performance wheels, not M3 wheels. Can’t remember the number, there was a 19” version for E9X cars. The 18” M3 wheels were 219 and 260, very similar. (I’m warming up, the performance wheels might be M269s).Gassing Station | BMW General | Top of Page | What's New | My Stuff
