Most likely a rear calliper stuck. If it is, and the disc is "blue-ed" and glazed (i.e.overheated) I would hold out for new discs and pads rather than just feeing off the stuck calliper. John

You do get a strong smell if the DPF is going through its clean cycle. |

Maybe, but I would worry about the O/S rear wheel area getting hot as per OP. John

I can confirm the wheel gets REALLY hot when a caliper seizes. My LHF caliper siezed (dust seal split) and caused weird shuddering, etc. Caliper was replaced plus BOTH discs and pads. Job sorted. |

I think thats whats causing my problem with my MY11 SD4 - im getting rear wheel judder when pulling away and it clears after a couple of seconds, I went to the dealer last week and sods law it didnt do it so have booked it in in 3 weeks time to be investigated unless it gets more frequent and i will chance going in to see them again, would discs and pads be covered under warranty if the calliper is replaced for being at fault? Now - 2017 BMW X3 M Sport Carbon Black

If the calliper has resulted in screwed disc and pads I would of course expect the whole lot to be replaced. Although they are "service" parts, this is not a case of reasonable wear and tear. John

Not saying it is, but the smell I get sometimes I also thought was wheel/ brake pad based. But I'm sure it is the DPF cleaning and unfinished. Get it after doing shorter trips, but always disappears after a longer run. |
