I haven't a schedule to hand, but I would guess the instruction is to replace the original tensioner at or before 54k miles with the latest spec part, then let it go to 108k and replace with the belt (because you could have had the tensioner replaced initially at a low mileage as I think some were done under recall regardless of mileage?) and then 108k intervals thereafter. It wouldn't make sense for Volvo to let an original go to 108k given the known issues, but I stand to be corrected
Tensioners do fail yes, but no dealership has ever told me change mine every 54,000 miles... The aux belt yes, but not the tensioner too. If I ask about a cam belt though, they mention the aux belts & tensioner. I don't think the dealership will just replace the cam belt alone? Maybe they will, but they'll put notes on their system to advise that you were told to change the tensioner & aux belt, in case of any come backs in future.

For peace of mind though, I replace the tensioner every 5 years or 54,000 miles (whichever comes first). Its not an expensive part... it works out less than a packet of cigarettes each year (£12 per year x 5 years = £60). For what its worth, it makes sense to replace the tensioner with the aux belt every 5 years/54k. I'm fairly sure Volvo don't specify that though, or never have to me anyway.

I did ask my local indy and they said their computer said both belts were 120k interval.

I guess the sensible thing is just to change them, but the whole point of dealer servicing was to make sure the right belts and tensioners were used given that them seem to have a had a few variants...

What would you do?

Your belts and tensioner are proof that a good deal more mileage can be made before failure. I work on 54000/10 years auxillary belt and tensioner and 108000/10 years timing belt kit but it must vary as some belts are only 5 years, probably due to different materials used.

No that's internet ignorance.. its the BELT not the tensioner which is the problem ,you really must not get your safety critical info from the internet ...

Aux belt ONLY every 54000 miles , It is the MILES which are important rather than time ...
The Aux belt tensioner gets replaced at 108000 miles next time it's due together with cam belt, and the next aux belt .. ...

Ferg, this confirms that the tensioner isn’t replaced every 54k.

I’d still replace it with each aux belt for what its worth.

I think we're talking cross purposes, I'm not suggesting the schedule states replace the tensioner each & every 54k (albeit we're all in agreement it's sensible to do so), I'm suggesting the scheduled replacement at 108k surely only applies once you have had the original replaced, and that it should be replaced either upon recall (or by 54k miles latest, or something along those lines). 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),

Were all models recalled to fit new style tensioners?

I'm not sure - perhaps the ones which weren't are considered by Volvo to be reliable up to 108k which could explain the confusion.

So on the bright side for me, my aux belt tensioner was changed in 2015, so after all the recalls so it should be the version that last 108k miles, so it's not overdue yet, neither is the cambelt.

It's only the aux belt itself which is a mere 40k miles overdue...

For a car that's had 9 annual services the record is a shambles, missed air and fuel filters, missed aux belt, random brake fluid changes. But they have offered to change brakes and tyres every time..

I don’t think all models were affected with the tensioner issue though. Yes, its confusing!

Get the aux belt changed ASAP... its way overdue.

I understand your point about the poor records. This is why I don’t go near dealerships. Some are good, but the majority are just rip of merchants & miss things that are supposed to be done.
