100k km is 60k miles. Nothing specific. The car is still young and ready to party.
Just to be safe you should replace the spark plugs and diff oil, change the oil and oil filter and the air filter. There is zero need to change the DCT oil until at least 160k km. People have already done oil analysis on them with that age and they're perfectly fine. Some people have mentioned issues with their charge air cooler, so make sure it isn't drinking coolant. If it is you have to replace the cooler. EDIT: please use ESS this time to tune the car! |

Remember the spun hub crank becomes an issue as you crank up the boost. If you want stage 2 I would consider the hub crank So you're saying BMW swapped injectors throughout the production run? If so it's news to me |

If you want bootmod I would limit the torque as they explain here

On the injectors I have seen many people with problems in any of them .. with 100k kilometers 60k milles .. I think it would be interesting since I will change spark plugs and coils to put them new too .. but I don't know what you think ..
It is also interesting to put the new lambdas probes. Another question, the adaptive suspension gives some problem or needs some maintenance .. ??? |

Definitely new primary O2 sensors Coils last over 100k km for sure. Until they misfire I would leave them alone. Maybe things are different if you're aiming for massive power. Eventually the suspension will need to be replaced, but you're probably fine at 60k miles unless it's leaking. You can always replace it for a non-EDC kit like the Bilstein B12 |
