Getting answers from Germany...

[T5petrol]

Hello all, I need to ask Vw Germany ,a question in relation to the new diesel engines that came out in the T5.1 update.
Does anyone here know the email address that I could use.
My question is ,"why do Vw Australian Dealers say to change the timing belt on the new diesels at 105,000 k's.?"
When the T5.1 was released in Europe with the new engines, one of the advertised advantages was, "extended timing-belt change interval: 210.000 km (up from 125.000km)
Now I realize that our interval here was shorter at 90.000kms, on the original engines, (not 125.000 km as stated) but only 15.000 kms extra on the new engines seem a long way off the advertized distance.
It has been useless asking Vw Australia.....maybe it,s just too hard for them .
Thanks everyone..... stay well.

I'm guessing it may have to do with VW Group classing Australia as a hot weather country.

I would change as recommended by VW - 105,000km or 7 years which ever comes first.

Thanks Phaeton, I too think that it could be our climate, but there is a huge difference in the figures . Germany says an increase of nearly 70% between replacement time ,with the new engines, as compared to 15% increase from Australian Vw.
I would like to discuss it with Germany, as they developed these new engines, unlike Aust Vw, who just sells them.

Whilst I may be wrong in my asumption here , VW Australia are probably just covering their own arses as they have done a back flip on transmission service intervals for the same reason . Australia is now a "hot " climate country gee who would have guessed that after VW have been selling cars for over 60 years here .

The distance may have increased but as far as I know the time interval is still 4 years in Europe & they still seem to break belts.
A lot of people reckon the Heat in OZ is hard on belts but my opinion is sub freezing temps on startup could be even harder.

For <2009 models with 1.9 l diesel engines, it's either 90 000 km or 120 000 km depending on the engine code.

For >2010 models with 2.0 l diesel engines, it's 210 000 km. For countries with high dust levels, it's 120 000 km.

Australia is classified by VW as a country with high dust levels.

...

It would appear that >2010 models with diesel engines have had their service intervals set at 20 000 km intervals (<2009 models set at 15 000 km). So on that basis, it wouldn't make much sense changing the cambelt at 105 000 km.

i can dig out the email addreess cause ive contacted them a few times. but your wasting your time cause the only response youll get is to contact vw aust.

Like Jfoldbar says...you are wasting your time. In a decade of T4 ownership the timing belt interval for my 2.5TDi has gone from 100K to 80K to 60K then to 60K or 80K and...now...ta!Daa!...105K. Which is apparently a blanket recommdendation for all VW Group diesels in Oz with timing belts...regardless of age, type or use.

And is in common with the aftermarket industry standard that every specialist diesel mechanic is familiar with...as my non-aligned mechanic says it's only taken them a decade to go back to where they started...

[buzuki]

funny, see this discussion nearly every single week.

The belt change for ALL vw is 105k 7 years. Excluding only LT i think which is 120k as they work off a 30k service interval.

If you dont want to do it then, its your gamble. But i think 100k is fair for a belt.

Diesel-vert ......could you tell me where you got those figures from....they seem a lot closer to what I was seeing from Vw release of new engines .Thanks to all replies
