Nov 9, 2022 · Timing chain parts are different on the N47 and N57 Just because of the higher forces due to the 8 more valves that need to be operated. The N57 is not known to have any timing chain issues. More peoblematic is the loss of cooling water due to the exhaust gas recirculation cooler (currently the 3rd one on my 535d N57D30Z). Risk of fire.

Jul 6, 2017 · Was this on an N57 engine? Just to report back on mine, so far so good. Changes are not 100% but in the last few days the idle is stable fter start up. I strongly suspect though that its far from over and would point towards injector issues or EGR or intake seals. Will report back when I'll give it to BMW for a few days (after the holidays).

Aug 7, 2023 · I heard from quite a few people that the 3.0 N57 has a lot of issues in terms of reliability, however google searches lead to people saying the N57 is better than the 3.0 M57.

So, to answer your specific question, yes, I think BMW should recall the N57 (and N47) engines. But, my opinion (and that of almost anyone else) counts for squat at BMW's corporate headquarters. In reality, the problematic engines were built over roughly a 20 month period.

Nov 5, 2023 · My vote is the N57. IMHO, BMW makes some of the greatest diesel engines in the world, be it 4 or 6 cylinder. I had the high performance variant of the N57 in my F15 X5 M50d. What an absolute gem of an engine. Amazing performance …
