Hi Levy,
please confirm. The 821E got a ZF 4WG200 or 4WG210. There is quite a big difference between.
Then lets make a plan.
Basically on both types there is no pressure gauge fitted throwing a low pressure code. WG 200 got a switch for low pressure, WG210 will indicate a slipping clutch with too low pressure.
