Jules59 Lieutenant    61Rep 540Posts Drives: Still searching ... Join Date: Nov 2010 Location: Wilds of Warwickshire iTrader: (0) | Difference between M57 and N57 diesel engines? What are the differences between the M57 and N57 diesel engines, including differences in ancilliaries between the 330D versions. Before anyone suggests "do a search" I have looked on various forums, google and wiki. __________________ Jules |

Swirl flaps, fair enough, but easy to remove, Turbo's are pretty much the same between the two engines, both using Garrett GT22xx units they do have higher fuel consumption compared to the N47 |

| jean019 Enlisted Member 5Rep 46Posts Drives: F32 435i RWD 6MT 2013 Join Date: Sep 2010 Location: World ! iTrader: (0) | There is some issue in m57n2 but you can solve it easily, especially if the car has less than 70000 miles. And the car is really reliable IF maintenance is done correctly (ie not like the dealer, for example oil breather has to be changed every 20000 miles, nobody do that except forumers), and the car driven correctly. No timing chain issue, no turbo issue. Maybe injectors but it depends on the diesel quality you put in it, and if you change diesel filter regularly (maintenance...). The N57 however has one big issue : it shares exactly the same timing chain parts that fail on N47. The issue happens at a higher mileage on N57 (approx 100000 miles), and the repair cost is between 4000 euros and 13000 euros (new engine). It's better to know it before buying it... Consumption? lol... I do prefer consume 1L more per 100km and not break the engine. Last edited by jean019; 02-06-2014 at 07:58 AM.. |

Replace them by blank plates, it costs 50 euros (only...) , and you will sleep better. Nothing like the 4000 euros timing chain issue. |

bayerischer Private  8Rep 78Posts Drives: 335d e92 Join Date: Aug 2016 Location: central europe iTrader: (0) | yes you are talking about blanking the swirl flaps. well guess what. my mechanic just did that coz my flaps were leaking, and that was probably due to the oil separator not being ever changed, so i will look at it. however, i am now considering buying a new intake manifold with swirl flaps, coz i lost power delivery, as others mention that too, however, some just refuse to acknowledge it. my mechanic and also other mechanics are suggesting to blank it saying you wont lose a drop of the power, but guess what, owners are complaining they lost some and i did too, so who is right!? and i suspect my fuel consumption went up and i think those flaps are there for a reason. i am even trying to eitgher call or visit and engine plant in Steyr austria where these engines and built, and ask someone who really knows his shit and not some joe knows it all without any credible claims |

Really? I would like to see some evidence on that one? The N47 (2.0d) engine yes I agree. But the N57 (3.0d) engine is solid. I run an N57 and a M57. The N57 is much better on fuel, no swirl flap issue, thermostats dont need replacing every service, glow plug sensors are not a serviceable item and the air filter is no a pita to change. I can actually find no reason why you would have the M57 over the N57. And like I said, I run both. The N57 has 172,000 miles on and the M57 has 160,000 miles. Both still have the DPFs in but the N57 has not once complained about it being clogged etc where as the M57 is constantly moaning if it is not on a motorway every other day. |

Not the same configuration either. Very few reported broken chains on the 6L ie: no more than random incident that would affect any manufacturers engine with a chain. If you're going to make such blatant comments to someone who is just seeking info. please you ought to make sure you have the right info. Its all easy for any of us to make a "mass" statement on something we thought we read somewhere on the old litterweb.  We had the same nonsense about Vanos with the S54 to the point where EVO wrongly stated it in a buying guide. I've had both engines and TBH both are pretty bombproof if well looked after as most cars, but these engines are certainly into a different league of performance and reliability than their competitors. |

| Rob330d New Member 0Rep 8Posts Drives: E92 330d Join Date: Apr 2019 Location: Ireland iTrader: (0) | Intriguing discussions on engine issues. Can anyone please tell me which type I have? (2006 e 92 330d se pre lci) Interested to learn if I've been wise with my 330d choice. Love the car for all the reasons you guys do but it's the first car I've owned that I'm afraid of breaking!! It's easily the most powerful car I've had but the first automatic. Tried a hard kick down last night at about 80 mph in D and dropped to 3rd from 6th. Is a 3 gear downshift normal at that speed? Are the auto boxes able to withstand hard revving. I know I've wandered off topic a bit here but can't help feeling that I need to be careful with this car as forums seem full of loving owners living in dread of lights on dash, DPF clogged, swirl flaps and the list goes on.... Funny that when I had less desirable cars in the past I worried less. I really love the 330d coupe for its looks and power......but are they as bulletproof as some say? Cheers Rob |
