In my haste to solve an airbag and srs light and also no horn.
I read it may be the rotary coupler or clock switch. Whichever term you prefer.
I sourced one and fitted it and in my haste to remove the airbag I did not see which way up the red plug attaches in to the back.
On my D2 the plug could only go in one way. However on the P38 it seems the connector is symmetrical and could go in either.
Without guessing. I thought i best ask if anyone knew
