An update on the power failure on my S4.
Returning from Le Castellet we had electrical failure involving headlights, brake lights, indicators & wipers - plus some panel lights- although all the powertrain electrics were fine.
Preliminary work has found serious water ingress behind the dash which has ruined the 'black box' which is now being replaced.
This is possibly a design/build issue affecting this series (& aeromax) as a similar problem affected an aeromax on the same trip.
I will keep you posted.
