Team-BHP - Attn: BMWs with N47 engines (320d / 520d)

I came across this BMW service bulletin which seem to imply that timing chain tensioners might not be keeping up with the timing chain expanding/ extending in time leading to potential engine failure.

Might be worth printing this out and taking it to your dealer during the next service

It would be a good idea if some list could be compiled or a thread started on which engines available in India were non-interference types, so that one could rest assured on performance or failure of timing chain not leading to damage to engine.

And given my budget this means that the model years that I am considering (2008 - 2012) would fall bang into the cars that we more problematic in this regard. Is there any information on how badly cars in India were affected and whether recalls were made?

Drive on,

Even if BMW has this data, it would be tough to access it. I would suggest you shortlist a few cars, then check their engine types and see if this fix has been carried out on them. If not, it is best to take a printout of this document with the car to the service centre and take their opinion.

Do you really think BMW will give a balanced opinion on this? I would factor in the cost of replacing the chain and tensioners as part of the deal and get this done!
