DV90 drive combined fault

[kieronthomas]

Hi all, can someone point me in the right direction, got a wacker neuson dv90 with a drive combined fault, won’t swap between low and high speed also flashes the foot brake symbol on the dash then trying to swap modes, flashes up a wheel symbol and exclamation mark, tried swapping the two sensors near the bottom of the drop box with new sensors but still no joy. Anyone point me in the right direction?

Do both the seat switches work when in that direction?
