Peugeot 208 2015 1.2 e-VTi Alternator Charging Issue

Hi!

I have Peugeot 208 1.2 e-VTi 2015 in today with fault codes on the BSI U1F1B Lin fault 21 and B132A aircone pressure low not charging and seating at 12.30V.
Alternator was changed with new and the battery, so far I checked wiring and scoped it from alternator to engine ECU and BSI, all fine all and is left to do online software update to the ECU. The engine ECU don't have any fault codes!

Thank you.

Regards
