This cannot be correct ??

My 320d has done just 20k km and was serviced last week. My rear brake pads have just 5mm (40pc) left. I was stunned too! The service report also says they corrected a software fault with the VIP control unit. The VIP unit is related to the braking system and DSC. I wonder where this caused DSC to be very sensitive and resulted in premature wear.

could you please share this service report? Here in spain we have problems with rear pads, with people changing rotors and two sets of pads with 50.000 kmts
Depending of the dealer, they're covering or not as a wsrranty service.
Thanks in advance!

here it is

Thanks!! but could you attach it with more resolution? Cant read it. Can you check if there's a PuMA code in report?
Again, thanks for sharing!!

this is what is mentioned in the report. "Programming/encoding control unit(s)
Found Fault in system for VIP control unit.
Carried out programming to rectifiy."

Thanks for the report, one last question, did you see in instrument cluster or idrive notification area, any error or message suggesting a VIP ecu error?
Is possible that here we're having exactly this issue without noticing it (no visible error or message)

Just got to the service centre for an oil change since that was the only thing the car needed.

They read the key and apparently car asked for a rear brake pad change. Checked it out and pads were almost worn out. Car is at 13.8k miles at the moment. Pad life clearly sucks since I have other cars I drive harder with more mileage and zero brake pad issues.

cookiecat · 06-26-2021, 12:39 PM

I just picked up a M340i MPE and so I hope that's not the case. I just returned a 17 440i MPPSK with over 44,000km and never had to change the pads or rotors. Rears we're still at 7mm.

Same. Sold my X3 at 35k miles and dealer asked of I never use the brakes since pads were like new. And this dealer said it's not the first G20 with this issue. He's seen many come in with the same complaints (premature pad wear).

Today I replaced the rear pads at just 28k km. When I asked, the service rep said anything above 25k km is normal! Also replaced discs even though wasn't mandatory. Expensive maintenance

PLF69 · 09-23-2021, 09:59 AM

Problem seems to be too much size disparity between front and rear pads.

We are starting to see 2021+ M3/4 guys going trough a rear pad set in a day or two of track work..

There is a SIB 34 03 20 bulletin about non M brakes - check it.
This also explains why M brakes owners have no issues.

Will the vehicle system check on Idrive tell us if the brake pads are low?

Nope. Mine was discovered when the service advisor did a key read. Car apparently said rear pads were worn and needed to be replaced. Nothing on the idrive indicating that.

That's unfortunate I'm sure they could have added that function if they wanted. I suppose all we can do is keep our eyes out when we take it to service.

My 2018 just had this rear brake wear issue.

Dealer replaced both rear calipers, pads and discs - @ 15500 miles and about 3 months out of warranty. Invoice cost was around £1200 GBP.

G30M · 06-22-2022, 01:58 PM

sounds like VDC/ESP activity from driving hard

iirc rear is single piston

Caio@Bullet · 03-23-2023, 07:51 AM

This problem does not only happen in the 3 Series.

Another car with this frequent problem is the BMW 540i (G30).

BMW should create a recall for this

Sounds like driver error or TC doing it’s job. I don’t believe it’s BMW error.
