I asked about the belt on my 3 yr old 60k 1.2 TSI at the dealer and they said it should be changed at 40k which sounds ludicrous, had a Citroen C4 before where they recommended 100k. As most of my mileage is motorway cruising they didn't seem to think it was that essential for it to be done. All seems a bit hit or miss.

It's a chain and not a belt.

Interesting post by rotodiesel, I've just done my 2nd cambelt kit and water pump change on my Roomster 1.9PD, still took me 9 hours to do. The car is only up to 50,000 Miles and is now on its 3rd cambelt. I think that is too much and for the 2nd time the belt looked fine when I took it off.

I'm sure that next time I will at least go 5 years before my cars 4th cambelt.

Well done on changing your own belt, but 9 hours? I didn't get that for an engine change lol

It's a chain and not a belt.

In my youth all cars had timing chains, they might have rattled but you never had to worry about them breaking so valves never hit Pistons. Does the TSI have a chain then, in which case the belt I can see is just for the alternator and water pump? So if that breaks does it matter?

Yes it took me that long including tools out to all put away again. I did a how to write up the 1st time I did it. Posted it in the Roomster Technical Guides if you have a look.
