Yesterday. Moved off up a hill. Slight judder. Bit weird. Since then I have had NO MORE juddering but I DO have a very odd grinding noise only on regenerative braking, more noticeable and low levels of braking. Harder braking that still doesn't involve the disc brakes removes the noise, and acceleration remains smooth and no judders. Volvo app says electricity still being regenerated on journeys.

It has actually quietened down significantly over the last few hours and is a very very faint whine now.

£125 to get it looked at by Volvo.

2 q's: recon its the ERAD and, if so, how much to replace? The pinned thread suggests in the region of £2k to £4k as I know different parts can need replacing, just wondering if anyone has more recent experience.

There is no manufacturer warranty, it is provided second hadn't by Sytner BMW (select). I have an email from the dealership in which they explicitly state it will be covered as I knew this might be a problem

Thanks in advance.

It may be brake related rather than ERAD, you might have had a stone or something trapped between the disc and backing plate and the noise has lessened as it has worn down, or pads may be worn down, it is the easiest thing to check and worth checking first before going to more expense.
