Reviews of OEM BMW timing chain

2014 F30 with N26 engine. 157K miles on original timing chain and BMW tech just inspected chain and guide after removing valve cover and said both are good.

Daca esti dispus sa sacrifici un pic la an si fiabilitate ( oarecum ) te poti uita si la un bmw 118-120d cu mentiunea ca posibil sa fie “mai manarita” la banii aia si cu vesnica problema a distributiei.

I have a 2013 328i with the N20. At around 140k kms I had a couple separate mechanics bring up the timing chain unprompted and note that mine may be on its last legs. I can\u2019t say I noticed any major symptoms or signs, definitely no lights on the dashboard.\n\nI bit the bullet and paid $3500 CAD to get it done at one of the best shops around, during which they do the valve cover gasket and a bunch of other key maintenance items.\n\nThey showed me how loose the chain was and brittle the guide was, so it was a good call. I\u2019ve known I would eventually have to get this done.\n\nCar is running mint since then.

Oil is cheaper than a new timing chain.

Most cars with timing chains never need them replaced, its just badly designed timing chains like the BMW ones that do.

You have the N47 engine, which is known for premature failure and excessive wear of the timing chain. However, it's generally cars prior to 2011 that have this issue, with later iterations safer.
