New Member Drives: 2009 bmw 128i Join Date: Oct 2012 Location: Addison, TX | What is the average life of a 128i engine Hey Guys, I have been driving my 2009 128i for sometime and the odometer now reads 99000 miles. I am soon to hit the 100,000 miles mark and now I have started to wonder whether i should continue to drive the baby till the time the engine doesn't break up or should I trade her for a newer model (trade value + some $$)? Does anyone have an idea about the life of 128i engine? How long can the car last in terms of miles if I keep it in really good condition (regular oil changes, general wear and tear maintenance etc)? Thanks in advance! |

Last of the classic BMW's- N/A straight 6, hydraulic steering etc. |

Ive put on 15 000 MILES in 5ish months and im nowhere close to getting bored.... and none of these miles are because work is far... |

Private Drives: 2020 Z4 M40i Join Date: Aug 2012 Location: GA | I'd love to go high miles on my 1'er also but in the 5 weeks I have owned it I've spent $1300 in maintenance and repairs so mine is starting to feel like "death by a thousand cuts". $360 was for a new battery and oil change. The other $900 + was for replacement of the valve cover gasket and oil filter housing gasket and related items. Service adviser told me there was a lot of oil on the engine so it was hard to tell but I may actually have a third leak at the oil pan gasket. And this is on a car with just 65,000 miles on it. Needless to say my confidence with BMW and the N52 engine is not at an all time high right now. |

Brigadier General Drives: 2014 M5 6MT Join Date: Nov 2013 Location: Massachusetts | Longevity of the car is completely reliant on the level of maintanance the owner does. If the car is neglected, it won't last long. If it's well taken care of there is no reason to belive the car, and engine, won't last 200+ thousand miles. If you were the first owner, and maintain the car well, it should last you a very long time. __________________ 2014 M5 6MT |

If the car is neglected, it won't last long. What is this based on? Do you know of a current BMW that didn't last long? And what level of maintenance is required? Over 20 years and 5 BMWs, mine have required almost nothing but standard oil changes up to 60K miles. There's more to do at 60K, but nothing out of the ordinary. The water pump's the only item to watch after that, if you have the N51/N52. |

Banned Drives: 08, 128i e88 Join Date: May 2015 Location: Fuck you | The water pump on a lot of makes and models are now one of the most important maintenance items. Any pump with a plastic impeller needs to be changed as interval maintenance. These impellers can break causing poor coolant flow to no flow depending on how it breaks. The broken pieces can then flow into passages blocking them causing damage later from hot spots. If prices become lodged in the block or head a new water pump is only part of your problem. |

Private First Class Drives: 2008 128i 6MT coupe Join Date: Nov 2011 Location: MD | My maintenance interval for fluids are based on Mike Miller's recommendations. its working for me. as he notes, all the diligent maintenance is performed so you will have great reliability after 100K+. unfortunately many people dont think that far ahead. That's why i only by a preowned with 30K or so miles as i think the owner cant have neglected the car, especially with BMW's "free" maintenance. and you're right about E30s. i bought mine from the original owner with 158K miles. it was a gem until I converted it to a SpecE30 and cooked a beating (yes, you do need to install an oil pan baffle!). 2nd engine just as strong with 190K on it. |

I'm not trying to pick apart what you're saying, but it's a given that scheduled maintenance needs to be performed on any car, just like how kids need to be fed to stay alive. And given that required servicing is done, the engine's longevity should fall within a narrow window. Perhaps if one gets beyond 200k miles or so, then the extra diligence to maintenance will show up, but few cars are driven that long. Other fault/ wear items will dominate the decision to retire the car. |

Other fault/ wear items will dominate the decision to retire the car. That's exactly what saying. Stay on top of the maintenance and the engine will last longer than the engines intended life span. I've seen plenty of engines with 500K miles on them due to this kind of maintenance. It's completely plausible. __________________ 2014 M5 6MT |

Lieutenant Colonel Drives: '08 128i Coupe SGM 6MT Join Date: Nov 2008 Location: Toronto | Not a statistician by any means but how can anyone at present time really answer the original question with any mathematical certainty unless there are N52's that actually start to fail and someone is tracking them. How can we know the average life of a mass production engine if none have come to the "end of life"? And then how would you determine whether they were all maintained equally? I'm sure BMW has some projections based on lab testing but I'd think for us owners at best you could do right now is take a poll of current mileage and infer what the current average minimum lifespan is not taking into account maintenance. I also find it curious that people reference how older BMW inline 6's have proven to be solid but doesn't the N52 have some unique design elements the others didn't such as the magnesium block? Not to mention BMW recommends a different oil weight vs the E46 which makes me conclude there are other differences as well? Is N/A I6 anything more than just a design philosophy / engine orientation or is it equivalent in the BMW world to mean two engines that are I6 are more or less built the same and are therefore comparable 1:1? |
