E46 DSC lights are on.

[wezzer-45's]

Hi guys,

I have a 2005 320cd
I recently had my DSC and brake light come on a few days agowhilst driving alond at 60mph.
They seem to go off them sometimes back on a few trips later.

I'm after some technical information regarding my codes.
I have
5E20 pressure sensor 1
5e24 pressure sensor

I understand that sensor 1 needs replacing and the code 5E24 is logged due to a difference between sensors 1 and 2.

Can anyone tell me which sensor is sensor 1 (front or rear of the master cylinder)

I've had a search an various forums but can not find out which sensor is which.

If anyone can answer this i'd be very greatfull.

I don't know which is which, but is it possible to disconnect them in turn and determin by the fault codes generated.

I recently found out from my very helpfull BMW dealer (Cardiff Sytner) that pressure sensor 1 is the furthest from the servo on the master cylinder.

As it stands, the lights havent come back on for a few weeks so I'll wait for the fault to re-occour before I fit a new one.
