Yep. My 16 year old BMW 118d (fully serviced its whole life, it was my company car before I bought it off the fleet) has now started to 'rattle' on startup, which is a sign of chain wear. Having to decide whether it's worth spending the money on replacing it and the associated components on a car which has some other 'life limiting' issues. But if I get rid, I'll end up running just the van since I can't afford to buy another car which is at all decent. Which means the van will then get loaded with all the short journeys and business journeys which the car currently does, as well as adding several thousand more miles a year to its engine. Looking at around £1000 pre-emptive repair cost on the car...Even though an engine has a chain drive to the camshaft, this doesn’t mean those are maintenance free. Chain tensioners break or wear (usually have plastic guides), the chains are usually simplex rather than duplex and wear resulting in elongation. BMW, JLR and Peugeot all have issues with chains.
