It took a little while and many contacts to organise, but to be fair Renault had the system checked and were convinced something was wrong. This prompted MannPower/ Parkers to re-check their own work and they found the problem... A piece of kit that is specifically installed to control the quality of the outbound electricity generated, had burned out a part. On replacing that part, the Zoe is now happy to accept our hydro generated electricity and we are set for completely green motoring!
