Your not gonna like this but...
If the Aux belt has bust... when was the cambelt last done?
Pays to do both at the same time, 30 - 40,000 miles or 2 - 3 years is max really for changing the cambelt and associated pulleys / tensioner.
So think hard... time to do both?
A busted Aux belt is a bummer... a busted Cambelt is a disaster!
very true ffoxy 
also consider this, why did it go ?
if its a badly cracked old worn belt there's ur answer if not,
i would check the crankshaft pulley or as there now know as harmonic vibration damper
reason i say that is if they decide to fall apart and they do
the pulley will almost certainly eat your cambelt in a very short time as in seconds if driving over 3000 rpm at point of failure
the car i just bought did exactly that after having new valves only a few thousand miles before
i guess the owner didn't want to shell out a 2nd time all because they fitted the old cracked pulley at the last rebuild.
it would be worth checking your idler and tension pulleys too some say change them some don't
if it feels right i usually leave it but thats just me
ps: cambelt and aux belt change takes around 45 mins to an hour if u know a bit about cars, gates timing belts for the cam is imho a must

Recommended Cambelt mileage/life is 74-75000miles (120000km) or 5 years (3 yrs with 'very demanding use' [cold climate, idling in city traffic, dusty areas]) so says the handbook.
There's really no point changing it before those limits.
If the manufacturer gives it that long, you can be certain they've included a healthy 'safety' margin, just to cover their own a##es against a load of warranty claims and the bad publicity that would entail.

i myself would never leave any cambelt more than 50,000 miles
the technology in the cambelts has not really changed in the last 15 yrs but the service/change intervals seems to have
there so easy to do on a multi if it was every 10,000 i wouldn't moan
its a matter of preference wether you leave it till the recommended time or when you feel it needs doing.
any oil,diesel etc on the belt will throw any normal timeframes out and a replacement asap is needed.

Whilst this IS what the manufacturer claims, real world experiences have shown it to be wrong. If a cambelt fails out of warranty at 50,000 miles who will foot the bill?
You do... end of really. Alfa have recently reduced their recommended mileage change period to 35,000 from 70,000 because of repeated failure and engine damage in warranty.
It's up to the user obviously, it wont cost me a bent cent if it fails, advice is free... repairs are not.

whatb to do ,the cambelt was changed in febuary ,will have to see if there is more damage to pulleys and such when it gets light again,i know my daughter wont be putting the fuel in again:bang:
if the cam belt is fairly new it should not need changing , as long as there's no damage to it.
i cant see how the cambelt was done but not the aux belt at the same time?
thats truly weird unless they were told not to replace it.
its a very easy job to do
peace
I guess it's up to the individual owner.
It's nice to hear it's an easy job on the Multipla.
Had a bit of a 'mare doing the one on my '99 Honda Accord (at 116000miles).
Sheared two 1/2" drives (one 'T'-bar and one extention) trying to undo the crank pulley bolt, a 1/2" Air Impact wrench wouldn't do it either.
In the end I had to weld the socket to a 3' steel tube (to get the end of it out from under the wing), then welded a 5' bar to that, and it still took most of my weight (11.5 stone dripping-wet) on the end of that to crack it .
I swear some of the other bolts are put in by fairies, they're in such inaccessible places

As someone who has spent many years within the motor trade as a main dealer (not fiat) apprentice then technician then a mechanic in a smaller 2 person garage. Finished this line of work about 10 years ago so not too many diesel cars around and no common rail jobbies.
I have very rarely come across cambelts breaking before the change interval. When it has happened there has been a leaking waterpump or seized / damaged tensioner to blame most often.
You hear stories all the time of so and so's cambelt broke and cost arggh pounds to fix but this usually happens (not always - there are always exceptions) when services have been missed - cambelts were previously changed without the tensioners or something else that should've been spotted getting replaced.
If you get the belt done by a competent person at the correct interval and replace the necessary worn / tired components you wont go far wrong. Keep the water and oil topped up and if you start losing any find out where it is going sharpish.
Sometimes lightning will strike but thats life - theres no need to over service.
Ask yourself how many people you know whos cambelt went within the change interval

The most common reason for the auxiliary belt to break is a wibbly wobbly tensioner. When I first got my multi the belt went so I replaced it, only to have it fail again 3 months later. The second time, I had the tensioner done and the belt's been fine the last 3 years.
The auxiliary pulley will eventually cause belt trouble, but by then it'll rattle so bad at tickover you'll be round the garage like a flash anyway...

I can immediately think of five in the last twenty years or so. And, of course, that's only the ones I personally know of. Extrapolate that to the wider world and I think it would add up to rather a lot!
You're right of course, saying that the problem's usually caused by a seizing water pump or a defective tensioner.
However, think back to the major warranty issues with Vauxhall's timing belts breaking due to the plastic jockey wheels breaking up - within the service times!
come on zundapp
5 in 20 years.
how many cars have the people you know had in the last 20 years.
as for a vauxhall warranty issue, does the multipla jtd have a plastic breaking up warranty issue?
i did say that there are exceptions but on the whole service intervals and belt change intervals are provided to keep the car owner out of trouble and in the most part they are correct.
if not the manufacturers reassess the interval - as in the case of alfa that was mentioned by someone else earlier in the post

I'm fast approaching 69 and have known nobody have their cam-belt snap for reasons other than another item's failure causing the belt to snap.
I have had my cam-belt snap on three occasions. The first was on my BDA engined rally car because it dropped a valve. The second was the fault of the garage failing to secure the belt tensioner correctly. The third was due to a faulty alternator pulley which caused the serpentine belt to fray and get under the cam-belt which jumped teeth. The vehicle was recalled by the manufacturer for a replacement pulley too late to stop it happening and, being Renault, they refused to admit liability.
I always let my belts run their full mileage as recommended and have had no trouble in that respect.
I never had a chain fail either although I did have some that rattled a good deal. I would have thought in this day and age chain drive would be a good deal quieter which was the primary reason for not using them. I much prefer a noisy chain to a snapped cam-belt!

Yep, kev78 - I'm probably looking on the bleak side - having myself had an expensive timing belt failure on a correctly serviced FIAT (not a Multi). But on checking your question again, I think I answered it as correctly and accurately as I could.
I wouldn't run a timing belt over 35,000 miles. I know what the consequences of a broken belt can cost. Changing it is cheaper and much less of a problem. That's my theory.
Other theories are widely available, choose the one you want!

Given your location Zundapp, I'd say you fall under the replace every 3 yrs with 'very demanding use' (cold climate...) part of the service schedule

gentleman i give thanks to all your much appreciated problem solvers .i will saturday morning take of the covers to check the cambelt, it would be my luck to put a new belt on and the cambelt snaps ,so thinking that logically i will get a cambelt kit and do the lot.:yum:

Hahaha You maybe right there! I tend only to need the aircon to de-mist the car... Although the sun does shine occasionally.
Bet you get through more than your 'fair share' of wiper blades too
