Bought an dead e-golf.....
Story of my 'new' 2017 e-golf mk7.5 pulled a code.
P0E7400 Hybrid/EV Battery Voltage Internal Isolation Fault.
20kms later the car became a no start and no new codes. Previous owner pulled the battery out, opened it and noticed water at the bottom and this is where my new ownership comes into place
I dried out the battery/sucked out about 3/4L of water. The capacitor is sitting just over 300V (instrument cluster is 32km to empty)
Thinking on putting back the battery and seeing how the car will act. Or if a battery cell module will pull a fault code. or or.
Is there any tests that maybe I should do before? Can I re-energize the battery with vag-com?
