L322 2007 suspension workaround/how to disable suspension

Hi, is such a great forum has helped me do small bits and pieces on my previous disco3 and now my L322 2007.
Currently have an intermittent problem of RR L322 2007 flashing up a suspension fault and going down to the bump stops.

I rem there was a thread somewhere that described a workaround to such a problem where you raise it to standard road height then turn off and remove an air suspension fuse in the engine compartment fuse box and from then you could get a day or so's drive out of it before having to put the fuse back - anyone know if this would work for a short period of time and which fuse should be removed to disable the air suspension?

...it seems on Disco 3' it is fuse F26E....anyone know which it is in the fullfatRR MY2007?

I can't find any information on the engine compartment fuse box anywhere online so can't find out what fuse to pull...any help would be great thanks

Rear junction box fuse 5R (20A) will prevent valve operation. CJB fuse 10P (5A) is the ignition supply which when removed will prevent the regular annoying warning messages, leaving only the initial warning message on start-up.
Don't bother removing the rear fuse 13 (5A) as that only provides a relay-powered indication to the suspension module.

Great thanks GraemeS...I took out the 20A fuse which was in the passenger side fuse box & the fuse F22 (60A) which was in the rear fuse box.

Took it on a short test drive and all seems fine, in that it didn't drop down to bump stops....so hopefully that will keep it moving for a few days while I try and hunt down the intermittent suspension fault, am expecting/hoping it to be corroded electrical connectors or corroded/crushed wires somewhere on the wiring loom as the fault codes pointed to CAN bus failure to communicate.

I had a problem with it last year where water was appearing in the driver footwell and this caused some electrical problems - anyone else had water leak problems that affected electrics?

Ive add photos here just for future reference

Sorry, I looked-up the 2010 diagram rather than the 07-09 diagram. 57P should be the 20A and 7P the suspension ecu ignition sense. The 60A in the rear is for the compressor relay so removing that wasn't necessary.

Be sure to check the codes as the most common reason for dropping to the bump-stops is that the compressor can't pump enough air for the vehicle to get to normal height after trying for about 5 minutes.

Perfect ok thanks, will put the 60A fuse back in.
With the intermittent fault, it can go for a week and no fault occurs or the fault can come on randomly with no common scenario being a precursor...after starting and if the fault hasn't occurred I can move the suspension up and down across all settings offroad/standard/access...
