| EPB / longitudinal acceleration sensor |
|
Help ! I have an intermittent problem with my EPB in mornings it flashes park brake fault and then the yellow brake light stays on, it only does this overnight. So I brought it to private Lr guy and he plugged it in and it is the longitudinal acceleration sensor fault but it will not take intsruction from the computer to calibrate itself ! So got electrician to check out power to epb unit and all is fine now my Lr guy says that I need a new EPB unit !! Bit  but park brake works fine and shoes and cables all in good condition ! Has anyone heard of this before ? Plz help bit peeved !! Supercharged grill, Economy chip, Chrome pack

Hi,
Did you get to the bottom of this, I have the exact same problem, did the sensor need changing?
Thanks.
Alex.

EPB light can be illuminated with none park brake faults . May be worth seeing if anyone local has a IID to check for you.

Got this one :
• C1A40-02 (A8) Longitudinal acceleration sensor - General failure information - general signal failure
And calibration with IID fails. So I was wondering before changing the sensors if it could be electric loom related.

This thread saved my life, thank you all !
I had a similar issue with a Range Rover Sport L320 2010 TDV6, and as said in this thread, when the parking brake module isn't mounted properly it can throw the code:
C0062-02 Longitudinal acceleration sensor
(notice the code is different for Dico's)
The symptoms that i had was that the car was lifted in the front, after few miles it will throw that error code and the car will be back to normal height.
Hope that helps.
