Problem with new engine diesel 2.0 n47 bmw in toyota

[Richard1982]

Hello I have a question about the faulty n47 engine installed in the new Toyota Avensis. Maybe someone knows when timing chain failure occurs, after what mileage and whether Toyota removes it at its own expense.

The car is warrantied for up 5 years / 100,00 miles from new and up to 10 years 100,000 with Toyota relax if you use Toyota for servicing, so long as the car is correctly maintained the chain would be expected to last vehicle life.

If you are out of warranty then you could ask Toyota for goodwill towards a repair but this would be based on your goodwill towards Toyota e.g. you are original owner or purchased used from Toyota and you have a full Toyota service history during your ownership if you can't satisfy any of these you are unlikely to get goodwill.

My recently purchased Auris has the N47 engine, and yes, there's quite a lot on the internet about issues with the N47, including the timing chain.  There will always be some engines, not just the N47, that don't get the correct servicing, which doesn't help.

Toyota specify engine oil changes annually, or at 10k miles, but in view of the N47's reputation, I intend changing the engine oil at shorter intervals, maybe every 6-8k.

Another issue, which I've not made my mind up about, is the EGR system (as with any modern diesel), and what attention I give it.  Presently I'm just seeing whether it gives any trouble, as most of my journeys are 20-35 miles, with not much town driving.
