After fixing my leaking ace pipes I’m now getting the yellow lean error and an error code of C1043 1C which is the rear axle pressure ? Code won’t clear and also all terrain response / dynamic driving is unavailable??

Yes I have the same issue, I haven’t managed to resolve this yet.

Have you made any progress?

Thanks

Hi yes its the rear axle sway pressure - you need to check your hydraulic pipes if there is any leak - if there isnt check your fluids - and if your still getting the warning your solenoid is probably shot on the ace block - you can try to take it out and refurb it - or buy a new one.

I bought a second hand one from ebay with warranty to solve my issue - I have my old block that Im taking apart and will refurb the bad solenoid. -

Thanks

Dumb Q what and where is the Ace block please?

So the ace block is just sort of under the passenger door under the car - if you search my profile I’ve done some threads on it - there’s 4 pipes that goto the ace block that run the dynamic system on the roll bars 2 front 2 rear - you’ll either have a leaking pipe that can be repaired or the block as gone bad.

You need to get under the car and pop the plastic under tray off sort of behind the passenger wheel and check if there’s a leak - or any fluid around your car - ans check the hydraulic fluid reservoir in your engine bay

Thank you, do you have the part number for the block please?

Here you go pal;

I have a spare 2nd hand one that needs refurbing its the rear bar solenoid thats not activating just requires cleaning out from the block.

Thanks Mate

Ive got a similar but different error C104A - front axle piston regulating valve.

The fluid is fine - it doesnt go down at all so im not suspecting a leak

Can anybody provide any guidance on how to troubleshoot this issue?

Ace block / valve yes same thing .
To the other OP - no leaks will mean the solenoid has stopped working on the block , you’ll need to remove the block and rebuild it / or purchase a new/working block .
