Hello, i think i have a weird one that i hope someone can help me understand a bit better.
My 225xe stopped taking charge from charger and fans spin full speed at all times. It was diagnosed at local workshop as a faulty KLE-unit.
I bought a second hand unit wich the local shop would swap and (program?) for me.
The local shop was not able to get confirmation in the display of the car that the high-voltage system was succesfully deactivated, and would not go through with the replacing.
I then asked dealer wich is located 70miles away from where i live, they would charge me about 2000 USD (price converted since i live in norway) to change and program the KLE-unit, wich i felt was a bit steep.
I then got a buddy help me replace the unit, took like 2 hours plug and play (followed youtube turtorial to deactivate HV-system). (Cover on old unit was corroded, big hole in coverplate).
(Clamped cooling hoses on unit).
Never tried to charge car before programming new unit.
Took the car to local shop again, they were not able to connect to the new KLE-unit.
The shop asked if i had vacumed and filled the cooling system, because it was crucial that the system was vacumed after replacing unit, and maybe that was the reason they could not connect to the new unit.
They further wanted -in writing- how, and what i experienced while replacing unit?
I have not gone any further, i just dont know what to think of the situasion?
