Anytime someone quotes "lifetime" oil, I want to cringe.
How can changing the oil, fluid ect. 'harm' the car?
If you only plan on keeping the car for short time (1-3 years) then get rid of it. Go lifetime. Then it's someone else's problem. (Not the way I would go, but to each their own)
If you plan on keeping the car for longer than that, then change the lubricants.....
80% of Zed owners on this board bought their cars USED. Think about that for a second. You bought a car HOPING someone took care of it. "head slap" :idunno:
This 'Lifetime Fill" that BMW advertises, is just to get you to the end of the 4/50 warranty. After that, you are on you own........
In an answer to the OP's question, Are you are really at 105 miles or are you really at 105,000 miles? I think your finger slipped. It happens.
If you are at 105. I would do nothing.
If you are at 105,000 miles, I would change both the gearbox and differential oil.
