Hi,
I know there's been other threads on this in the past but I thought I'd see if anyone had any more ideas or solutions.
Recently my handbrake and DSC lights came on and wouldn't reset. I plugged the laptop in and got Fault code 5E21, no. 2 pressure sensor. When I checked the active pressures there was about a 10 Barr difference between the two braking circuits.
I changed the pressure sensor (it was second hand so I could have bought a duffer) and the brake fluid and gave both circuits a good bleed. The lights went off, thank god I thought.
Then, the other day both lights back on. 5E21 again, however the lights aren't on permanently. When the lights were on the was a difference of about 5 bar this time. The lights are now off and the fault cleared but I think they'll be back soon.
Is there anything else that could cause this before I go forking out on a new sensor (probably should have done that first)?
Any help would be appreciated.
Thanks
