2010 BMW 320D failed timing chain

Asked by Daniel

I purchased a 2010 BMW 320D for my wife in January, but just six months later, in July, the timing chain snapped causing
 catastrophic engine damage, not to mention the dangerous sudden stop on the 
road. It has done 153,000 km, many of them cruising on the freeway, and a full BMW service history. The dealer wants more 
then $4000 just to diagnose the problem. Looking into these cars with 
the N47 engine, it appears that there is an engineering issue resulting in 
thousands of failures worldwide. BMW denies this, of course. 
Could you please outline options available to us? Can we not 
reasonably expect BMWs to last even seven years when well maintained?

The problem with the N47 diesel engine dates back to 2007. There are plenty of overseas reports of the timing chain failing, as yours has done. Deal directly with BMW head office and seek some support for the cost of repairs. It is a problem, and BMW should bear some responsibility for it. If you can’t get any help, go to the ACCC and make your complaint to them.
