I am getting these fault codes on my citroen ds5 2012 model
Only the rear passenger door opens with keyless entry all other doors don't open
Getting these fault codes hoping someone can give me advice on a fix

With so many of the same type of fault, it's more likely to be the hands free unit itself as these faults are either short circuit / open circuit faults.

Your code reader is unable to provide the full fault codes as it's missing the last 2 numbers, so I can't determine the exact issue. For example your code reader just gives 2 identical B1727 faults, when it could be:

B1727 11 (Front left door handle fault: Short circuit to earth) or
B1727 13 (Front left door handle fault: Open circuit)

But in either case it will be wither the hands free module itself, the door module or the electrical harness.

I'm also assuming you have not spliced any wiring or taken feeds off wiring for other equipment or added any aftermarket devices...

Only bought the car the other day and scanned them to see for faults as the doors didn't open
