HDC fault on startup looking for some help (FIXED)
Fault occurs every time on startup HDC fault, special programs off suspension lowering...
Car runs fine, gears show on dash, speedo works
Brake warning light RED and ABS light ORANGE
Tried:
New brake switch (have D4 LED lights)
Battery is new and 12.4v
Charging @ 14.2v
Checked wiring NSF and OSF inc earths (not tried rear yet)
Checked plugs behind battery
Brake pads/sensors okay
ABS wire/sensors look okay
only stand out code was - C1B02 Return Pump Circuit
Clear faults and it drives 110 yards then re-occurs
Could be me but think can feel ABS under brake foot sometimes??, brakes normally though!!
Any help appreciated..

Is all normal until you pull away?
If yes, you need to recalibrate the steering angle sensor. Mods:
Front Fogs + Halos
FBH Remote Control
The 1st Ever RRS Modded Grill
Garmin Nuvi + D4 Surround + Reversing Camera.
D4 Steering Wheel.
Rear Boot Spoiler.
Twin Brake Lights.
Wing Mirror Indicator Repeaters.
Long Roof Rails

I'm not scared, I'm outta here.

Sorry Narpy, meant to add only 2deg out and reset SAS
Removed/cleaned ABS pump wiring connector and added big F transmission and limp mode to list of faults
Re-assembled connector, let car sleep then drove home, brake and ABS lights went out as normal
Not 100% convinced fixed as running with fuse 26 pulled over weekend to ensure ride height so still have HDC bong/light
Will update next week if sorted....

ABS pump located in 2nd battery box
Wiring connector on front left of pump
