150,000 miles on this engine.

That's one heck of a mileage Wheeler

I think, for peace of mind, I'd like to change it a bit sooner than that.

Any incidences of them letting go that you know of?

All the current DV engines (1.4 & 1.6 HDi's) are 150,000 miles (or 10 years)
The DT17 V6 HDi fitted to the C6 has a timing belt replacement interval of 160,000 miles (or 10 years). The extended intervals are one of the 'advantages' of having a dual mass flywheel. Don't think i would personally leave them that long either.
Not heard of any early failures on either of these engines.

Huh

How does having a DMF extend the life of the cambelt? Don't get that one at all...

Citroen say the flywheels are designed to
filter out acyclic engine movements of the engine suddenly accelerating & decellerating at the start & end of the power strokes by using the stored energy of the flywheel. They reckon this in turn puts less stress on the timing belt therefore extending its life.

Thanks Wheeler 8)

That makes perfect sense

I'd still not like one to go that long though...

I also think 150k is a tad optimistic, just like most of the other service recommendations!

Co-incidentally I have just booked mine in to be done next week. Car has just over 96k, may be a little over cautious but if I didn't have it done soon and it ticked over the 100k mark I'd be driving around very paranoid!

Citroen however don't tell you that the DMF will have to be replaced on average every 50k...so the saving of 1 timing belt replacement (assuming a life span of 80k) will be totally wiped out and then some.

I would say modern cars have now become a total liability....with all of this technology that's supposed to be improving things the cars have became a lot more unreliable.

Cheers.
