Hi
Has it only just started happening? As there any warning lights on I know it's a silly question but have you just filled up you car, in which it may be worth checking the receipt just in case wrong fuel was used, as it does happen?

If not have you driven anywhere where water could get into electrics or engine then not too sure but probably best to start with reading the cars on board diagnostic (obd) port to see If any faults in the system.

That would point to any issues, most garages have them any some forum members have bought just an obd reader to help them identify any issues.

The car only does down hill at 1500 rpm and brakes start clunking going to main dealer on wednesday

Thank you for advice Graeme bmw are paying for calliper and glow plug control unit as long as I get new discs and pads along with brakes shields fitted by dealer

Hi
That doesn't sound too bad but depends on price as I know calipers aren't cheap and the discs be pds etc will be a lot less..

Just glad it's getting sorted

They replaced both front callipers new discs new pads and also replaced the shields . They replaced glow plug control unit as it was showing a fault on there system .  The dpf was replaced three months ago along with both rear airbag suspension I paid £645
