My auto hand brake does not work, and I have a perm ant warning light on my dashboard. The car is a 540i touring 2018 with 38000 miles. Following a paid for £225 diagnostic report the local dealer (used them fo 20 years) has advised replacing an N/STOCk hydraulic unit at £2566 +£303 Labour to solve the issue, which is need to pass an MOT test later this year. The fault has been apparent for over six months and passed MOT in Nov 2021 will not now? Originally when the fault appeared the service team advised to wait until car next in other work, which is where we are right now.
can this be right for an auto brake issue? Any advice appreciated
thanks
