TBH, you have one of the most popular engines manufactured by BMW. The same engine used on hundreds of thousands of 1, 3 and 5 series. Your main concern, knowing that you live in Toronto, will be the road salt eating away at the body over the years. Metal is metal and the body will begin to corrode. The engine is protected with the plastic underbody and the engine will last much longer than the body. Maintenance is paramount, so making sure there are no oil leaks and keeping the engine tuned up should present no significant issues.
If you want some real world issues, head over to the N52/51 engine sub forums for the 1 and 3 series and write down how many engine issues people have on the first three pages. Then do the same on the N54/55 subforums and you will notice a significant increase between the two. As for personal experience, my family had a 528i and we still have an X3 with the n52 engines....120k and 89k respectively with no engine issues at all.

No, obviously not, but bmw has been producing inline sixes for a long time, assuming that they have, at the very least, the same longevity targets as previous models you can guess how long they can last. This was never a truly scientific discussion to begin with. Most newer cars from what I've seen with high miles has everything fall apart around the drive train, I'd be willing to bet you'd start getting sick of sinking money into a depreciated car before you have to replace the motor.

One of my daughters is driving a Corolla with over 240K miles. The other daughter got a new RAV4 and we have her old Jeep with over 180K as a spare. Neither has had significant engine work. Both got regular oil changes. My other vehicle is a SUV with over 110K miles. None of these vehicles need oil added between changes.
The only unusual thing about the n52 is the silicon aluminum block with no iron cylinder liners. Porsche has been using that design for a long time but they aren't known as high mileage sort of vehicles. Reasonable expectation these days is for the engine to last indefinitely with proper maintenance.

No mods, basic maintenance service, and the engine will last as long as you stay proactive. From what I can tell, the motor itself is built very well and has done me well as a commuter car.
I'm about to turn 114,000 mi. and drive a pretty good mix of highway and city, and take it on a lot of trips back home from NC to MI. 10/10, would drive over and over again. In fact, I will happily in about 4 hours. |

Sos, Bluetooth And Viberating Car
gee! I just bought a used 2009 BMW 128i non iDRIVE Convertible noticed that mine fairly used bought 2009 128i BMW non iDRIVE convertible shows the SOS sign, with consequent loss of the Bluetooth function and audible which was working before. The radio works and CD works. Can this failure effect the performance of the Engine. This condition has been on for days now, even with offing and restarting the Engine. Mine car shakes with resonance at low speed and increases with the speed. It was checked and was told the engine is fine only the Oil level sensor needs to be changed. really afraid that mine engine will not last. Can any body advice

The vibration is not normal though. it could be misfiring cylinders, unbalanced tires or alignment or about 50 other things.

I've had BMW's for the past 12 yrs six cars and a motorcycle. Every one of them has had valve cover leaks, except my current one because it only has 18k miles. There were problems with the ones with some milage and it was expensive but in my experience BMW makes bullet proof engines, it's just everything thats bolted on to them thats the problem.

the N51/N52 use the exact same part as the N54 and ALSO fail at the same intervals.....have nothing to do with turbos or no turbos. |

http://www.e90post.com/forums/showthread.php?t=725313 i'm not saying that a water pump MUST fail....but it is certainly a known part of failure which will leave you stranded on the side of the road; so quite important, IMO. |

Now at 193,100 miles. No engine troubles at all since I bought the car at 35K miles. BTW, this water pump now at 73,000 miles and I'm not planning any preventive replacement until I hit 240,000 miles (if I keep the car that long).
Did replace all coils and plugs at 191,000 mile tune up. |

167k miles. Going strong! It has 3 track days under its belt, one in extreme heat, one in extreme cold, and one was just perfect. I've got to do a coolant flush, just to make sure everything is in-order, and my alternator's bearings are very noisy, but it charges just fine. If you're looking for a reliable, fun, sporty, German coupé, look no further...unless you have money, and the capacity to buy turbos for a 135i, then get one of those instead...
N52, 6-Speed, BTW.

That's a lot of miles! That BMW N/A straight six is like the Energizer Bunny, it just keeps going and going and going...

I think it's a high enough failure rate to warrant replacement at 100,000 miles at the LATEST. Overheating a BMW I6 means head gasket loss and a warped head, or at least that's what it meant on the M54. I'm taking no chances on that when I can absolutely prevent it with a few hours work on a weekend.

That said, I preemptively replaced my water pump and thermostat at 100k on my E82. Failure and overheating is still not a preferred outcome. |

Yeah I'd rather not wait a couple hours for a tow truck on the highway or where ever it does it whether the engine is going to be okay or not.
