Coming up on 70k miles. What should I prepare for?
Got a 2013 F10 M5 that is coming up on 70k miles. I haven't owned it for long, but an oil change is coming up, and probably new rear brake pads/calipers as well.
Since i'll probably be taking it into the dealer, i'm curious if you all recommend anything to be looked at/done at the same time when it comes to this mileage. It drives great, I haven't had any problems. I've kept the car stock. Though i'm starting to notice signs that it might have been modded before by the previous owner. Dealer aside - if you have other recommendations to watch out for when reaching 70k miles i'm all ears. |

I would do the following for POM (peace of mind)
* replace all spark plugs and coil packs * flush and refill rear diff fluid * flush and refill brake fluid * oil change with Blackstone analysis Optional : * replace fuel injectors |

It really depends on what has been done for maintenance so far. For example, if you just did all of the fluids at 50k, most of them don't need to be changed again yet. Since you haven't owned it long, I'll assume you don't have maintenance history. These are things that should be considered if you don't know when they were serviced last, if at all:
-Engine oil/filter -Engine air filters -Cabin air filter -Brake fluid flush -Check protection level of coolant -DCT fluid/filter -Rear differential fluid -Spark plugs -*ignition coils -*injectors -*MAF sensors -Primary/precat O2 sensors Fluids/filters are what they are. Do them or don't do them yet; if you need to spread out some of the work you could forgo some of them until next oil change or two. I highly recommend the precat O2's and spark plugs be changed this time around. You should notice an improvement in "driveability" especially if the O2's are original. The MAF's are another area that could show better performance after 70k miles. I've replaced everything mentioned above at slightly different times and noticed at least a small improvement each time... small improvements I didn't think the car needed! *I hate replacing parts "just because", but the coils are known to fail and if you buy them from RockAuto they are dirt cheap. The injectors are another crap shoot. If you don't have problems with them, you could probably wait longer before replacing. You won't save that much labor (if any if you don't watch what they bill for) by doing them at the same time as the plugs/coils. Good luck! |

Thanks everyone. This is a great list i'll use to check things off. I had some of these in mind and so it's good to see others bring it up as well. Open to recommendations on what else to service/watch out for.

Any signs of injectors going bad? Feel like you would know before blowing the engine. there is an extended warranty to 10yr/120k. Obviousely if modded then you chance not having things warrantied

Also have a 2013 M5. What causes these to fail? Poor fuel? do they just get clogged?
I only use Shell 91 gas and run a fuel injector cleaner every 3k. Not sure the cleaners make much difference |

Injectors can fail in multiple ways, the worst way being stuck open and filling the cylinder full of fuel, causing hydro lock. This will usually result in a bent rod or a rod exiting the engine, piston and cylinder damage can occur also without the failure of a rod. I might be changing mine in the future as preventative maintenance. I would imagine BMW would cover injectors under their extender warranty but its very unlikely that they will pay the full amount for a new engine because of a failed injector. To my knowledge that particular BMW bulletin has not been issued in the UK. |

In the early days before failure you may notice the occasional misfire but again you may not. The biggest contributing factor is the type of fuel used. I only use shell V-power and that's all I've used in 2 years of ownership (except the odd time when I've been caught out nowhere near a shell garage). I don't know what previous owners have used though. |

If the wear has already started to occur then it will carry on, the components inside the injector will move in such a way that the wear will become worse over time, despite cleaners etc.

Injector cleaner may/may not help. An "induction service" is a waste of money. I'm sure the procedure is different from brand to brand, shop to shop but back when I worked at a dealer, the induction service was not very helpful/didn't really do much.
Re: injector warranty - always an option to wait for one to fail. Just know that BMW will try their hardest to deny a new engine claim if said bad injector hydrolocks your engine. Also, they only replace the failed one and nothing else. IMO for the relatively cheap cost of new Bosch injectors and the peace of mind that comes with it (and potentially restored power or driveability), it's not worth pinching pennies by holding out for extended warranty |
