Citroen C4 2012 1.6 e-hdi
Stop/Start deactivated

I have the following fault codes that came up after the alternator belt snapped;

P1A9C Energy accumulator: state of health fault

P1AA2 Voltage retaining device: internal electronics fault

P0272 Correction of injector flow rate cylinder 4 :Injection time too long or too short

Everything worked fine until the alternator belt snapped and it had hit the crankshaft position sensor and its connector plug causing them to break. The sensor itself was replaced but since Citroen doesn't sell connector plugs separately the connector was fixed by a mechanic.

I have examined the connector myself and it seems that it was fixed with glue and lots of it. I then managed to find a new connector and now currently waiting for it to arrive hoping that this would actually be the cause of these faults. It should arrive sometime next week.

In the meantime I came here to ask if someone here happens to have a similar problem and maybe a possible fix for all of these!

I should mention that I have examined the voltage retaining device located over the front left wheel and everything looks okay altough my OBD scanner says that it only has 0.95V - 1.0V (ignition on/engine off).

Please help! Thanks.
