Hi all

Disconected the battery today on my L494 Sport now have no HDC, Traction control, Height control, Terain selection and very strange very stiff steering at about half lock to the right any ideas ?

Did you let the system shut down fully before disconnecting the battery.
Might have caused the problem if you didn't.

Open the car up, shut the doors, leave the bonnet open and wait 10 minutes. Disconnect the pos terminal for 10 minutes and try connecting again. If that fails something is probably goosed. 2019 5.0 SC SVA (Current)
