CVD calibration or delete

Hello
I bought back my old L322 4.4tdv8 my2011. Past owner did change rear shock absorber due to some accident. he said old ones blew up when he replaced some rear axle bushes... New shocks are also cvd shocks but it gives fault code from them, i wonder do they need to be calibrated? It causes special programs to be off, i took plug out of cvd module and now special programs work but there is still fault message.

I tried to disable cvd ccf with iid tool but it caused abs dsc etc stopped working.

Ride quality is good but yellow triangle in dash is annoying.

Check continuity on the wiring and examine wiring at the top of the shocks as this is a common fail point. There is a reset function in the GAP IID tool if you replace the ECU module but not for replacing the shock units. 2012 TDV8 Vogue (L322)

iI it is real CVD then you have broken wire. Just replace cable and should be ok.

Aah then those are fake ones.

I changed ”Constant variable damping system” ccf from fitted to not fitted but yeah it gives loads of errors after that. Abs dsc ebd and so on

Any clues?

I checked workshop manuals but couldnt find wiring diagram for active damping module. I tried to put 2.2ohm 5w resistor but it still gives C110E-14 and C110F-14
