i have had amber warning light on for a couple of weeks now and today the light was no longer on.So I’m driving along at 40 and hit a bump and the car starts rocking side to side non stop on it’s own (road smooth by this point) it stopped when I stopped for a roundabout.Then the amber light came on.About 10mins later the red light started flashing and bonging.Pulled over to check fluid-Max,no signs of any leaks anywhere.
Plugged in nanocom and it gave me these codes
18-04 hydraulic or mechanical fault in pressure control system
20-04 pressure control valve fault
22-04 hydraulic pressure too high
23-04 pressure signal out of range
37-06 ecu fault
40-06 fault with residual pressure value

Any ideas what could be causing this???
Any help or advice is always appreciated

Thats great,anything of any relevance to the question to add?
I drive the car once a week.i wasn’t losing fluid then so wasn’t overly concerned

Clear codes and see what comes back

Probably sensor or ECU

Is there a way of temporary disabling it so it doesn’t throw the red light up?

This sounds like the age old method of dealing with sudden and unexpected noises ...... turn the radio up until the noise can no longer be heard.
I appreciate that you find the little red light somewhat annoying, but the reason it's there is to alert the driver that something is wrong and requires attention, not just eliminating the light.

Know anyone with Hawkeye?

They seem to talk to ACE better

I would also suggest picking up a cheap Ebay ECU to swap in, just in case.
