This car is beginning to drive me nuts
Its booked in for a full diagnostic at the main dealer on monday to clarify the problem with the ECU on the suspension for the warranty company, they don't believe my Indy

Anyway now my PDC system has gone off altogether.
When i put the X into reverse I get 1 short tone then nothing except the light flashing on the switch. Neither of the front or rear sensors appear to be working.
I have listened to them all individually and they all appear to click apart from 1 front 1 which does click but not as loud as the rest.
Would 1 sensor being U/S cause the rest of the system to fail ???

same thing happened to me in the last cold snap.
lost warning bleeps and just had a flashing light on the pdc switch.
my scanner detected front acoustic generator error but it was too cold to remove bumper and have a look.
anyway, after a week and back into warmer weather, it just fixed itself and has been normal since!

Hairdyer on it if you can.
