Hi
As I know, Linde has been replacing the turbo charger of all truck model H50D H2X394 free of charge since it is a system error from Turbo charger supplier.
Please swap over the turbo charger from the other truck to see if the problem come from it.
You can contact your Linde Dealer in local to request them to replace the new one and flash the new software in order to synchronize with the new type of Turbo charger.
