I have a C4 Grand Picasso Diesel Auto 1.6 2013 and only have done 7700 miles.
Suddenly the Start Stop function has stopped working. The ECO light flashes
three times and nothing happens. The battery is fully charged and noting is
draining the battery. I have already checked all requirements for the function
to work to be ok. I have a Autel Maxidas d708 and it throws error A4D4 Fault:
Rear door sills or boot lighting fault : Short circuit to positive ,

I have checked all connections and lights to be working and nothing appears
to be short circuit. However on further diagnosis I found that in BIS system
one item failed ( Number plate illumination control Actuation failed ), however
the lights are working. The rest of functions on car are all ok. The DTC code comes back upon clearing.
Please help. Thanks in advance.

Take it for a half hour drive, not in town and it will start working again.

The eco does what you have described when the battery is at 85% or less, &/or the temperature in the cabin hasn't reached what you've set the heater &/or aircon to.

Or if the wind is in the wrong direction...there is a 'Y' in the month, the sun has risen in the morning... you get the picture!

I took the car for 100 miles run on M3 motorway and switched off all devices and climate control and yet still it shows the same DTC code and still Start Stop does not work. Every thing else is working. Strange !

To be quite honest, if mine stopped working I wouldn't be bothered, it can be a pain in the neck sometimes.
