[123Britt]

Heading to the dealership on Monday for my final sub 50k warranty covered service.

My question is: At what % of pad life is required to meet the free pad & rotor replacement?? I have 12% life left per the BT.
.
335i - so looking for S. Plugs, Brake Fluid Change, HPFP Recall Program and new wipers & the rotor and pad replacement if I qualify.
.
.
Thanks in advance.

The wear sensor will tell you if the brakes are low (you'll have a brake light on the dash) and the car will tell you when you need new plugs.

In my experience they don't do any work unless the car is asking for something. The BMW free maint program for me ended up being an annual oil change (every 18k miles) and a few air filters along the way. Since everything is rated as a "lifetime" fluid or rated for 100k miles of service...

I didn't need brakes until 60k miles, so I ended up eating that cost. Tires wore out at 60K, my DMTL pump and headlight died at 65K shortly after. Can't really complain since every car would need these things, but I walked away feeling the maint program was pretty bogus.

Maybe your experience will be different.

I think it's bogus too...but... you didn't even get an Inspection I? Coolant flush -- isn't that at 3 years? Brake fluid?

There's a wear sensor attached to the pads. If the sensor is not triggered they will not likely replace the pads unless you can actually show that pads elsewhere on the axle are below minimum (IF I recall. The factory pads are 11-13mm thick depending on front or rear, and the sensor is suppose to trigger when it's down to ~3mm thick). Technically, even if the sensor, which is only attached to one of the 4 pads, was not triggered, the MINIMUM operating thickness is still the determining factor although most dealership will just tell you to bring the car back when the light triggers.

There's also a minimum thickness standard for rotors (yes they do wear down over time) and it's typically 1-1.2 mm below the original thickness. Rotors will only be replaced when they reach that minimum spec.

If you are planning on doing ANY performance oriented driving, any time the pads go below 30% of original size they should be replaced, since the thermal capacity of the pads to resist fade also decreases.

I put at least 3k a month on the car with my commute, so yeah I'm sure they did the inspection, but rarely will newer vehicles need anything. No need for a coolant flush or brake fluid, I was about 50k miles when the car was less than 18 months old! Lol. I put miles on so fast and the BMW didnt require any maintanence during that time. They may have replaced the coolant or brake fluid, but it wasn't necessary. I don't remember. Overall I'm satisfied with it so far.

Car may have a lot of highway miles but everything is like new. Runs like a champ. I'm replacing all the fluids and maybe plugs now at 70k so it stays that way.
