Probably the haldex controller scan it with vcds I had to replace mine not long ago would wheel spin in the dry

Scan for fault codes might be a start... if the haldex has gone then there will no doubt be a communication error fault with the haldex

Haldex can be disabled for various reasons... ABS fault, wiring issue, haldex controller problem...

i've scanned it but wasn't with vcd was with delphi system i've got...no fault codes

Check the earth strap that runs from the top of the haldex unit to the underside of the floor, they can corrode and break.

Certain scanners won't read all codes when I took mine to the garage they said there was no fault codes so I had to go back with my laptop and vcds lite on it for them to do it.
