Timing chain weakness

[chriz1]

Which engine is it likely to affect ? The 163 or the 177? I'm in the market for a 320d m sport and recently found out about this common and expensive issue.its putting me off buying to be honest...

E90 engines I thought they had sorted the swirl flap issues never heard of a e90 going cause one has failed,turbo seems obvious enough regular oil changes and newer designed vortex style breather. Most talk seems to be timing chain noise or breaking don't fancy a 5k bill for new engine..

Well that's out me off buying an e90 BMW then,as my budget puts me in this range of engine,oly things can do is look for a early 57 plate with low miles that had the older 163bhp engine,as buying the 177bhp engine is a bit of daft decision espically as there are so many cases
