#1: Auxiliary belt snapped suddenly... Author: Gumpy54, Posted: Wed Jan 14, 2015 1:27 pm ---- Ok, so was just pulling off at a normal rate, and the aux belt snapped, causing the battery light to come on the dash and lose all power steering. Ok, I can fix that no worries.
However, seemingly at the same time, the environment control unit (digital heater / aircon) also switched off. No display, nothing.
Are these related? I checked all fuses in footwell and in engine bay and all are good. When I fit the aux belt, will it work again?
All this after some scrote broke my passenger window.
Getting fed up of this car...

#3: Re: Auxiliary belt snapped suddenly... Author: Gumpy54, Posted: Wed Jan 14, 2015 4:26 pm ---- Agreed, but the environmental control unit display in the dash? Would it stop working altogether?
I mean, there is no display at all. Only the backlights to the buttons when I switch the headlights on...
Getting the belt done tomorrow, so I guess Ill find out.

Author: MrBSI, Location: What's it to you? ? ?Posted: Thu Jan 15, 2015 5:26 am ---- Even the non plexed BSI units as in the OP's car are smart enough to know to shut down any high load electrical devices when the charging system is defective so the car can limp as far as possible before the battery runs out of power.
#6: Re: Auxiliary belt snapped suddenly... Author: Gumpy54, Posted: Thu Jan 15, 2015 7:41 am ---- Excellent news. Thank. I'm glad it's not one more thing to fix.
EDIT: All done. Took less than half an hour. Was a sod getting the tensioner back because my spanners are quite short (oo-er), but once on the environmental control worked again, just as you guys said
Not bad for a pug beginner
#7: Re: Auxiliary belt snapped suddenly... Author: Gumpy54, Posted: Mon Jan 26, 2015 5:00 am ---- Update:
The belt shredded itself
Seems that the tensioner bearings are going? Would that cause the belt to jump off, and / or shred itself?
If so, I guess I better get a tensioner as well as a new belt
#8: Re: Auxiliary belt snapped suddenly... Author: panther12, Posted: Mon Jan 26, 2015 5:39 am ---- Can you feel any play on the rollers with the belt off. I'm currently doing a head gasket on a 2005 206 and will need to replace the aux belt tensioner as when I took the belt off, the pulley is very wobberly and surprised it never threw itself off with the amount of wiggle.
#9: Re: Auxiliary belt snapped suddenly... Author: Gumpy54, Posted: Mon Jan 26, 2015 2:37 pm ---- Pulley feels solid enough and cant detect by hand any 'roughness' in its rotation, so can't be sure its the bearings, but better safe than sorry I guess.
So, to change the tensioner, simply use a 15mm spanner to tension the spring, undoo the securing bolts (2 of them) and it comes off? Refitting is the reverse?
