On my E93 I drove it like i stole it during break in and it was a beast afterwords. On my G83 I followed and slipped up a couple times and everything is fine. M division breaks it in on site but it’s up to the consumer to make the valves seat properly. With that said, to each his own.

@OP if you drive in Comfort mode (assuming the M3 Comp listed in your bio is the car you've bought and therefore it's an auto!), you should find that if you just drive around normally the car will manage the revs well enough to keep you under the 4.5k-5k rpm mark.
Obviously you need to avoid putting your foot to the floor so it doesn't kick down or run to a high rpm under heavy acceleration. I actually didn't have an issue - it's more of an inconvenience that anything else. I took mine out for some scenic drives around the Somerset countryside, like Cheddar Gorge and some of the rolling B roads near Dartmoor. That way you can still get some real enjoyment out of the car as you're still doing a decent speed, just in higher gears and without hard acceleration. Towards the end of my running in period I was a bit gutted to see it tick over from 999 to 1,000 miles, as it's a nice feeling driving around in a brand spanking new M3/M4 with super-low mileage! |

Update from me: My CS is in for it's RIS this week, so very soon I'll be able to press the fun pedal to the floor

Performance cars need to be driven like performance cars ocasionally
Saw a comment saying an owner drives "98% in comfort," and think this applies. As a wee lad I bought a '60 MBZ with a perfect leather-wood interior but a crap rust-out body ($75). Then I bought a '61 of the same model (220Sb) with a crap interior and solid mechanicals ($300) from a 'little old man' who had babied the car. Three days later I was driving up a steep hill, downshifted, and took the RPM up to w/i 500 of red line. I cracked the top piston rings in two cylinders. The car had been so babied that the piston wear in the cylinders did not extend as high as it would in an engine that had been driven normal or hard (piston rods do stretch, a little). The rings hit the ridges that had formed due to the wear pattern, and the rings cracked. That was my first engine rebuild, thankfully with a father who was an ex-airplane engine mechanic and who had access to a machine shop. I got five years out of that car and engine, and sold it to a guy who wanted a project-car for when he got custody visitations with his kid.

No car is going to show signs of damage caused by improper break-in after only 12,000 miles. So you just passed the problem to the next owner. I wonder if you told him that you drove it like you stole it during break-in

If your commute is on the freeway then put it in sequential mode and vary between 7th and 8th gear.

Hi I’m brand new to this forum. I’m looking for advice. I have a 2024 S58 G80 Xdrive Comp. I recently installed the JB4 tuner and obviously noticed a big difference in performance. I want to add down pipes to this set up anyone have recommendations on which down pipes I should install ? That’s compatible with the JB4 tuner

My bad I initially read his comment as using launch control BEFORE the break-in service. Afterwards launch away! 🚀

Are you guys overlooking the considerations from 1200 to 3100? They’re not as stringent RPM wise, but they’re still there.

Edit: I do see it says "during break-in do not use Launch Control," not sure if the 1200-3100 period is considered break-in though. |
