The Tesco chargers are hit or miss for me.
but it might be worth another go when the weather is wetter
as i find some will work when its wet that would not work before.
As a solution i have not found one yet.
There is updates that Renault do for a price but even that might not cure
the problem.
I am thinking of getting the Brake Fluid and coolant done together and that would include any updates at the same time, The cost from DSG Morecambe was £420.00 when i asked in June 2022.
I try to try to use mainly 22kW chargers from MER , Raw charging , Connected kerb and Geniepoint which so far work everytime.
I think its down to the installer of the chargers and how good they are with fitting the earthing of the posts.
I went to Gridserve in Norwich and tried the 22kW and ended up with my cable being stuck there for 24 hours.After my Zoe killed the power to the 22kW Charger.
So my cable was stuck in the charger overnight , Gridserve did lend me a cable until the next day.
It would have been nice if Gridserve could have of warned me first,
Because a few hours before i arrived another Zoe and a Leaf had the same problem but lucky for them there was someone on site that could reset the charger.
