My S Class broke down

It's called risk assessment!
In our case it's essential that the car returns to the pits using only the driver 'and the tools carried on board'.
The idea of a shell change is an interesting one, but I doubt it could be done without the car coming to a halt.....
Crank sensors not showing up as a fault is quite typical of the intermitant failure mode of these parts. Least they are not silly expensive, although I have never bought an MB branded one!

No problem so long as the "tools carried on board" includes a TIG set , Lathe, Universal Mill, Pillar Drill, Plasma Cutter , and not forgetting a STAR diagnosis set - no , make that two STAR's .

My car seems to be half way there with the shell change idea - at least it disassembles itself while it is still moving.
