Need of electrical diagrams

[six112]

Hello.

I have a 2015 C4 1.2 THP 110 that I've bought with some electrical gremlins.

Currently the battery is dead and I have no info what so ever, but before that it had a crank, no start issue.
At the moment when turning the key, nothing works and when turning it back, the error lights on dash light up. When the ignition is on, nothing happens. Also, when using the central locking, the left rear door lock is left clicking. I currently put those on the empty battery.

It would be great to get any wiring diagrams related to the BSI/ECU power.

The VIN is VF7**************[VIN obfuscated, can be read by forum staff]

Best Regards,
Siim

That won't help at this stage, you really need to get a diagnostic run using Diagbox to see where the faults are pointing.

More importantly, you have an urgent After-sales campaign outstanding on the vehicle, so as soon as you can I'd get that booked in, it won't cost you anything. These EB2 engines have issues with the timing belts as they run in the oil and can shred up and disintegrate, blocking the oil strainer and can affect the braking vacuum.

HLT - Timing belt

Vehicle reliability and your safety are a major concern for the Brand. As such, the manufacturer has asked us to check the components of the braking assistance system on your vehicle that could be damaged by a degradation of the timing belt in order to avoid any risk of reduction or loss of braking assistance.
