Aux belt snapped

I heard some squeaking on startup this morning… booked in with the mechanic for a service and what I suspected was a squeaky aux belt…


Driving home this evening and lost power steering and battery light came on. Had to battle on another couple of miles as I was on a smart motorway. Pulled off an aux belt is shagged. Thankfully looks like there is no damage to anything other than the aux belt.

Unsure if I need to buy a lottery ticket or if I’m incredibly unlucky with it going the day I booked it in? 🤣

You’re very lucky, if the aux belt had wrapped up on the crank pulley it could have taken out the timing belt as the lower timing belt cover is made of flimsy practice.

Your next move should be to find out why it snapped - you might have a seized or partially seized component driven by the belt.
You don't want to replace the belt then have the new one fail soon afterwards.
 
As above, very lucky it didn’t find its way into the timing belt.
Check that your alternator pulley hasn’t seized, it should freewheel one way.
 
Looks like

Maybe with the colder weather approaching the alternator etc is working a bit harder now and breaking belts that are a bit weakened.

looks like there is quite a bit of play in the alternators pulley and the belt jumped off and shredded. Lucky it was booked in for Tuesday anyway for a new clutch and flywheel as that seems to be on the way out. Will have to do it all at same time
 
You got lucky if it didn't murder the timing belt.

Rule of thumb to reduce risk is a new aux belt at timing belt time, and then a new aux belt 50% of the interval towards the next timing belt, ie, two aux belts for every timing belt.
