Hi All,

After a recent car wash (hose not high pressure) I got the amber warning light.



I used my IID Tool to read and try and clear the faults. Unfortuantely the IID was unable to clear the faults.

The codes I have are:

C1b03-1d(af)
C1b07-1d(af)
C1b03-18(af)
C1b07-18(af)
C1b11-1d(af)
C1b11-18(af)

When using this link

http://www.rrsport.co.uk/gallery/albums/us...erview.pdf

it comes back that I have "high resistance' in the "Directional Control Valve 1 & 2 circuits", plus in the "Pressure Control Valve circuit".

The diagnostic is to check check the relevant circuits... So does anybody have access to these circuit diagrams/ connector locatoins and what do I check?

I presume once I get the diagrams first thing is to check all connectors are secure and have no moisture etc. After that I'm kind of lost.

Any help would be appreciated.

Thanks

Hopefully this will help. It looks like a vavle block problem or at least wiring to and from it or the Control Module.

However, any tips still gratefully received

Cheers

Well, looks like the module is fried, or at least partially. The sunroof drain pipe was damaged and leaked onto and into the unit causing some point corrosion

So looks like I need a new/ used replacement unit. The part no. I have is NNW 504025, I've been offered an identical part but with number 7H32-5A482-AB and another with part no. AH32-5A482-AE D1778...

Can anyone confirm that I can use these and just get them coded with my VIN??

Thanks in advance.

I've been having problems with my ACE system.

I spoke to parts a a LR dealership and requested the part number for the ACE control module, the number they gave me was: NNW508200

That part number NNW508200 comes up as: Control Unit - Roll Stability Control - Genuine Land Rover, the RSP price inc VAT is £334.56p available from Rimmer Bros and our own sponsors such as Duckworth Parts or AF Advanced Factors, may be able to give you a discount. John

Thanks Guys

I'm guessing a used unit isn't advisable?

Thanks
