Yes, indeed it is.

Puzzle:

The WR uses 035 959 481B - a 100C switch.  Works fine.

The MB uses 034 919 369B - an 85C switch.  Indistinguishable from above.

The MC in my 100TQW uses the same switch as the MB - 85C.  Yet it seems
to 'pulse' the fan - the on/off cycle can be as low as four seconds.
I've tried swapping senders between the cars, but the behaviour goes
with the car, not the sender.  Odd.  Is the Type 44 under-bonnet
geometry _that_ different?
