I haven't seen reference to the this problem anywhere else on the forum, but apologies in advance if i'm going over old ground. My C5 (2004, HDi, VTR, Estate) has started to show an unwanted windscreen wiper feature. Automatic Wiping becomes active even when stalk is in the "off" position. As it has been dry recently this results in a single wipe, then another a few moments later (say after about a minute). So far this has happened twice but in the following scenario: Car not used over weekend 1st engine start, Monday am - problem occurred, drove about a mile and stopped engine. 2nd engine start, Monday am - problem occurred, drove about a mile and stopped engine. 3rd engine start, Monday am - problem not seen drove about 4 miles and stopped engine. 4th engine start, Monday pm - problem not seen drove about 1 mile and stopped engine. 5th engine start, Monday am - problem not seen drove about 4 miles and stopped engine. 6th engine start,Monday am - problem not seen drove about 1 mile and stopped engine. Car not used on Tuessday 1st engine start, Wednesday am - problem occurred, drove about 2.5 miles and stopped engine. 2nd engine start, Wednesday am - problem occurred while engine running on garage forecourt, then stopped engine. 3rd engine start, Wednesday am - problem not seen drove about 2 miles and stopped engine. Is likely to be a problem within the wiper stalk that takes time to "go away" - say some sort of intermittent earth fault? Last week I had a single incident of an airbag warning error, but that cleared after restarting the engine and has not come back. The light sensor works with the headlights correctly.
