Cayenne 2008 cambelt or timing chain

[KilburnBloke]

I'm trying to figure out if a 2008 Cayenne 3.6 V6 Petrol has a timing chain or a cambelt?

And what is the recommended service/change interval on one of these?

It's done 68,000 miles in that time and last had a major service 18 months ago (before I owned it).

Thanks

All Cayenne range are chain drive engines with lifetime chains - no replacement interval.

The VR6 engined cars have rear mounted single row chains while the V8's have front mounted duplex versions.

Diesels are chain too - single row type with gear driven cams; with 2008-2011 cars also having a belt driven diesel pump while 2012> cars have chain driven pumps instead
