Hi Cranium 4 - the mileage and service details may be entered manually in the App.Cranium4 wrote: ↑Thu Sep 05, 2024 12:08 pm Had my C5 PHEV for 14 months now. Shortly after taking delivery of the car it would not go into electric mode due to ambient conditions. Often shutting down and restarting would overcome this but not every time. The car went back to the dealer after 3-4 months to fix an unrelated problem. At the same time they advised me a system update had been carried out. Since then I can only recall seeing the problem once.
When I took delivery the electric range showed 39 miles. For the next 9-10 months when fully charged the range would be 29-31 miles. Since then the range has crept up and is now 34-36 miles when fully charged. No systems updates have since been carried out. this incudes the 12 month service and none by myself as I have insufficient broadband speed to download the GBytes of data. I used to be able to check for system updates on the app but since it was updated recently it no longer works properly, wrong milage, all recent trips missing and says no service carried out - so I dont know if any are due.
I do a lot of short journeys on electric only and find the 12v battery under the bonnet needs charging now and again or the central display will not turn on when the car is not powered up and the keyless unlocking becomes hit and miss - I can only guess the battery drain is probably due to the alarm when the vehicle is locked
I too would be interested to know where the aux battery is located in the boot and what it is for.

Not sure what you are referring to. On a PHEV you will have the traction battery in the boot and the 12v ancillaries battery in the engine bay.
If your ancillaries battery is approaching 5 years, it should be replaced now in any case, as its capacity will be degraded by this time. I wouldn't play about with the PHEV Traction battery.....

Ok, so on this model it's in the rear not the front; that silver ECU is the network isolation device.
The is (a larger) one in the front too.Juan Sheet wrote: ↑Fri Sep 06, 2024 5:05 pm Ok, so on this model it's in the rear not the front; that silver ECU is the network isolation device.

Thanks for the picture, will find mine and see what it reads. Would be interesting to know what each of the 12v batteries powers, obviously the one in front is for starting the engine but as for the rest ??

If you have the VIN, I can see exactly what systems you have. Send it via a PM if necessary.
