High mileage n55
My car just hit 80k miles. My extended warranty expired in about 444 miles so I went to Bmw for an issue with Bluetooth to figure out how to fix it and they ended up telling me the issue along with:
2 oil leaks ( covered under warranty ) valve cover gasket and not sure about other one. I'll update once I know. Intake inlet pipe cracked and the vacuum hose completely broke off(not covered) 400 too fix. Last month my charge pipe blew from just regular 50mph driving which I did upgrade. If you have a higher mileage n55 I would go get it checked because I never realized any of this because the car drove fine. I recently switched my aftermarket intake and threw the stock on and when I started my car it was acting weird and that's when I realized the inlet was cracked. I have a 3rd party warranty that I got pretty cheap too so I'm happy I went with it when I bought the car. Just throwing this out there for people to check because I thought my car had no issues and boom. Hopefully it'll run new for a while now and give me a few years of 0 issues lol.

Every person has there own opinion. This post is geared towards just higher mileage n55's. Whether your 70,80,90,100+. Different cars at different miles things happen to this is just to give others in the same boat some info too look for to possibly help them.

Note: This is the pipe that connects on one end to the pipe that comes from the airfilter box across the top of the radiator. The other end of the Inlet Pipe goes down to connect to the inlet of the turbocharger. |

My car is at 78K miles and I just noticed I have the same valve cover leak (i'm guessing its on the passenger side of the engine above the turbo?). Apparently its common issue in these cars as the gaskets they use wont stand up to the heat over time. My car has also give me zero problems for the past 3.5 years of ownership until this.

As far as I know the part is not expensive but the labor is a lot.

I'm not too entirely sure. It's at bmw now. When I get it I will let you know. They told me it actually had 2 leaks. The first tech only saw the valve cover gasket leak and when they called to update me they said it has 2.

Most likely your Oil Filter Housing Gaskets are leaking as well. Common problem on every BMW and BMW refuses to address it with better gasket material. Direct Injection motors get hot and the gasket material basically becomes plastic over time with the heat. I've had both replaced on my F10 and F30. Had the same leaks on my E90 as well.
Other high mileage issues you are approaching is the waterpump and thermostat. BMW likes to use plastic and those get just as brittle and fail between 80-100k miles.

That's the joke about their covered maintenance being shorted and limited as well that BMW's are so expensive to maintain, even BMW can't afford it

OFHG leak at 67k miles, covered by Route66. Going in next week for left lower strut (or lower control arm as they're called I believe) and steering wheel column rattle.

They thought there was a leak on the oil pan but they want to fix it and then have me bring it back after 1k miles to make sure the oil on the bottom pan isn't just coming from the leak up top.

Yeah the leaks seem to be fairly common over 50K miles. I had my OFHG go at about 70K and the belt tensioner went shortly after that. It is an annoying rattle at low rpm that will drive you crazy. Part number on this is 11287594969. I would replace the belt while this is being replaced since you will have it off anyway.
Another thing to keep an eye on is the plastic hose going from the coolant expansion tank to the radiator. Mine became very brittle and snapped while driving. Coolant sprayed everywhere and I got stuck on the side of the road. Part number 17128570061 in case anyone has this happen. |

i have a 102k fbo 2014 bmw 435i that i just got misfires on. read on forums that it could be the spark plugs or ignition coils. i upgraded to ngk spark plugs 2k miles ago so couldn't be it. so i narrowed down to either ignition coils or a bad fuel injector. i just replaced all 6 ignition coils and still having a p0302 misfire code in cylinder 2. so most likely will be a bad injector. anyone have experience?
