Hi,

I have a 2014 Range Rover Sport 4.4.

I had minor accident on front right corner 6 months ago and the wheel bent the ace pipes in wheel arch.
I had the section of pipe repaired by hydraulic specialist.
The car is coming up with these faults:

C104A-94 - Pressure regulating valve - Unexpected operation
C104C-94 - Pressure regulating valve - Unexpected operation
C104B-94 - Pressure regulating valve - Unexpected operation

I read online that these are common faults for if there is air in the system. So I took it to an LR independant garage and they a bleed using LR system. As shown here:

The fault is still there. and the garage say they don't know what the cause could be.

I'm looking for an independant specialist who might know how to fix this. The faullts are obviously coming up due to incorrect data being logged on the components on ACE system, but it needs someone who knows what they are looking for to identify fault.

I appreciate any assistance

If you're happy to travel, I have used James French 4x4 near Oxford for a number of years. As good a garage as I've ever used and have always been honest and straight forward to deal with. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Give Langley 4x4 a try, they're real good.

They're at Kings Langley so not too far. 2015 Range Rover Sport L494 HSE Dynamic
