Zoe not charging

Hi, I also have a Zoe Ph2 (bought second-hand two years ago after my PV system was installed) and charge it almost exclusively via an EV charging station NS. This winter, when temperatures dropped below freezing (at the end of December), I had massive problems and the car had to go to the repair shop several times. Renault provided updates and reconfiguration, etc. Now, a few weeks ago, when it got very hot, the same problems came back. But now resetting no longer works and the car no longer charges at all. Renault says that the charger (BCB) is defective and wants almost €10,000 for the repair (replacement of PEC and motor). Other independent garages want €3,000-5,000 for the repair. Could the EVCS deviation with the IEC 61851described here have damaged something in the Zoe charger?
