Newbies reading this post up to the point I chimed in could have come away thinking their original tensioner can run for 108k, and that just didn't sound correct to me.

Clan, I was sure it is the tensioner and not the belt which is the primary cause based on Volvo issuing four recalls specifically for tensioner failure, see below. Or maybe I'm missing something. I thought they had redesigned it several times to address the problem?

AUXILIARY DRIVE BELT MAY DETACH
Recall number
R/2010/033

Recall date
01-04-2010

Recall type
Safety recall

Reason for recall
The Auxiliary Belt Tensioner may fail resulting in loss of Power Assisted Steering and loss of Drive


ENGINE MAY LOOSE DRIVE AND POWER STEERING ASSISTANCE.
Recall number
R/2011/175

Recall date
23-12-2011

Recall type
Safety recall

Reason for recall
The auxiliary drive belt tensioner may fail. This can lead to loss of steering power assistance and a slight possibility of loss of drive should the drive belt or tensioner invade the cambelt area.


LOSS OF POWER STEERING ASSISTANCE
Recall number
R/2013/140

Recall date
28-11-2013

Recall type
Safety recall

Reason for recall
The auxiliary drive belt tensioner can suffer from premature wear which may cause it to fail. This can lead to loss of steering power assistance and a slight possibility of loss of drive should the drive belt or tensioner invade the cambelt area.


ENGINE MAY LOOSE DRIVE AND POWER STEERING ASSISTANCE.
Recall number
R/2010/058

Recall date
26-05-2010

Recall type
Safety recall

Reason for recall
The auxiliary drive belt tensioner may fail. This can lead to loss of steering power assistance and a slight possibility of loss of drive should the drive belt or tensioner invade the cambelt area.(and I do agree that it you may as well do it anyway given the low price of the part),
It took them a while to find out that it was the belt failing rather than the tensioner . due to severe tugging on the belt on the first few firing strokes after start up .


Older pre 2007 thick wide aux belt no problems .
New models :
2008 std tensioner but thinner narrower Aux belt for the new Mk 3 cars which are pendulum mounted .
2010 a mod introduced to fit a hydraulic tensioner at the factory .
2012 - 2014 ish still a problem
so final Dealer mod to drill the block to refit the original tensioner and a new more compliant belt introduced .
2014 the above being done in the factory now for the remaining engines until the 5 cylinder phased out .

Its always worth asking the dealer if all the remedial work has been carried out .. or any outstanding ...
