550i vs 535i maintenance/reliability etc
So I'm in the market for a used f10. After driving the 550i I'm obviously leaning way towards it over the 535i lol. However, I've heard horror stories about the common problems with the 550i engine. And obviously the 535i has its problems, but overall I've heard it's more reliable and less of a headache to maintain. Any inputs?

535i is hands down more reliable. That is why I purchased one after considering a 550 vs 535i as well.
The N63 is garbage IMO. Most if not all BMW tech / enthusiasts agree. That being said, if you have the budget for a N63TU I would probably pay to play. My techs claim night and day difference in reliability. Maintenance and repairs remain $$$ for both versions of the F10. Although, the V8's will generally be more expensive. Logically. |

every car has their share of problems so saying one is more reliable than another is just nonsense. If you scared about reliability just take out a warranty. Route 66 on 550i is really not bad at all. Mine is good for 5 years/100,000 miles.
Put a Jb4 on the 550i and you get close to the same power as an M5. 550i is really a "M5 on a budget" :-) |

Haven’t had an issue at all. Right before I head in I just deactivate JB4. Before the 550i I had a 335i with jb4, intakes, intercooler, and dp with the same warranty and also never had any issues.
At the end of the day they getting paid so I dont think it mattered to them either way. |

Never denied and process them quick. You are only responsible on paying the taxes, that’s it.

My experience with N55's:
I had a 2011 X5 535i (n55) and had little issues like injectors a couple of times, Vano recall, drive train malfunction, oil gaskets leaks. Which are really minor problems. Traded x5 for a "14" 535 N55 and I haven't had any issues like the "11" N55. I'm guessing the original N55's had a lot of bugs which they fixed with the Newer N55's type B engines. Only problem I've had with the 535 was the AC which BMW replaced..Both motors I ran BMS JB & BMS intake.

as mentioned try to look for a later model year f10 (either way you go) specially for the 550i in 2014 they came out with the n63 tu and there is alot of enhancements in terms of reliability.
the n55 which originally came out as a twin turbo (forget the code) in the 335i in 2004, had alot of issues early on, this is why i never buy a car in its first 2 years of production run, i typically like to buy one thats been out for 3 years at least or wait and get the LAST model year.... |

I have had a 335i N54, 650i N63, and now a 535i N55
The N63 had numerous issues. Injectors, coils, battery drain, etc. N54 was trouble free and the N55 I have now has over 40k miles with no issues. |

The twin turbo V8's 550 and M5 both are vulnerable to coolant leaks. The plastic T's and hoses in the turbo lines get fried and start to leak, and the cooling radiators up front can be damaged from road debris. My 550i got a puncture in the turbo radiator and pumped it's circuit completely dry. No problems on M5 so far. Basically, with the V8's you need to be even more vigilant about checking the coolant levels regularly so you stay on top of any developing problem. Other than that, haven't had any engine problems.

the N63 V8 engine in the 550i is utter garbage and best avoided at all costs. even the TU version introduced in 2014+ 550i's is still full of issues.
The N55 engine in the 535i is actually a very reliable motor and has far less issues. If you are looking into an F10, this is what I would recommend buying. you can also get a downpipe and tune the ECU if you are looking for more power. I would say that the 535i has the perfect amount of power for the F10 chassis, and that the 550i's power levels are really not that necessary unless you plan to remove the speed limiter and do triple digits in the left lane on a day to day basis. my point is, that the 535i is not much slower at legal speeds while being much more reliable. it is also much safer and easier to control in the rain/snow, which gives you the added benefit of being able to opt for RWD, which is a huge plus with these cars. |

I've thought about doing the JBx route but with the age of the motor i'm scared to stress it out. |

I had an N54 135i before and I loved it.
When I was in the market for the F10, I wanted the closest thing to an F10 M5 that's a lot less. I settled on the M-Sport 550i. I bought it for performance, reliability 2nd. I also didn't like that fact that 535s and 528s are everywhere. 550i are lot more rare and it has a cool factor. Also, the V8 motor sounds, you can't even compare. Added a tune, and this thing is a beast. Overall, if you are focused on reliability, stay away from either. |
