Is the wading kit the one that pressurises the transmission, axles etc?
If so how is that actuated as there is an airlock from the carden shaft door when the diffs are locked that I assumed to be failed locker seals (my U1000 has that job to do

).
And yes I did think that was a big knob on the end of my dipstick

Very little welding to do (just the windscreen surround) which i very welcome after the epic U1000 cab rebuild!
Is there any way to tell age from a Mercedes chassis number?
