L320 . 08 plate. Reading the manual for GAP it does say on page 106 that it’s all possible to read live values . I’ve just updated the tool so will see if it’s enabled the ecu list .
Measured the resistance on the Pressure control valve ant comes 5ohms and I measured my spare one snit 4.9 .
I still can’t see the live value of the Dynamic roll ecu .

Looking at the wiring diagram I have there is a junction /connection on the loom from the PCV to the module , so a bit of puzzle to find . I can also pick up the voltage again at the plug to verify voltage and earth qualities . Although I am sure I have done this .

I also got an email back from GAP saying that they provide the same list LR does with their official diagnostic tool. BUT, unsure about this specific one .

Update, I have just got an email granting me access to the ACTIVE ROLL ECU , so just a question of installing into GAP tool .

we are getting somewhere hopefully.
So now I have the Active Roll EcU and scrolling down the various components and values therein . I get this —with engine running and fault light on. Any interpretation would be helpful , but it still looks like a wiring fault , there is good voltage to ecu module .





Problem resolved for now.
