3) change oil/filter at 1200 miles or so, or after one month, also consider changing diff and transfer case fluids


I bought a new 2013 535 and think I probably failed to follow all of these tips. *shrug* Right after my purchase I went on a trip to visit friends and put 300 miles on it at highway speeds with cruise... During that trip I may have raced a few people on the highway and also gunned it a bit for fun. It ran great up to when I traded it 3 years later. Absolutely no problems. So take it as you will.

My 2018 x3 M40i will be here by xmas. I will probably try to be a bit more gentle with it.

I tend to stay under 5k and that is difficult enough. Play around with the different modes and don't sit in the same RPM range for too long. I am staying away from ECO pro until after break-in. Changing your fluids at 1200 miles is as important IMO.

Nope, I'm just gonna drive it until the computer says it's time.

This is my long-term commuter and I opted for the extended warranty+maintenance. Fingers crossed I made the right decision, but this transmission is widely used in the industry, and while the B58 motor is fairly new, the optimist in me believes BMW have learned from their previous failures... hah!

Step 1) Sport+ mode. ie. Sport mode then push Traction Control off
Step 2) Shifter into "S" (not "M")
Step 3) Mash the brake hard with your left foot
Step 4) Mash the fun pedal

At this point it'll pop-up a flag and something like "Launch Control Active"

Step 5) Release the brake

Just remember to be careful and sensible. Also, I believe the manual recommends driving around normally for 6 miles after using Launch Control, to help everything cool down.

If that doesn't work for you, there's plenty of Youtube videos on it.

I have 2000 miles and when i asked the dealer if i should bring my car in for the 1200 mile check up, they told me it was not necessary for this car. Any advice on why i'm struggling with this??? And yes I only try it after the car is warmed up with 6+ miles driven since start. Thanks!

Here's the relevant section from the M40i's owner's manual. Basically, you definitely DO want to follow the break-in procedures for the first 1,200 miles but there is not a recommended oil change at the same time. I confirmed with my dealer that an oil change is not necessary as the BMW oil filters are more than capable of trapping any small particles that may occur from seating the rings.
