Inside a Porsche Taycan's £30,000 Dead Battery (Main Dealer Couldn't Fix It)

A Porsche Taycan came to us after the insurance repair was rejected — and now the owner is left facing a private repair bill of over £3,000. Was this fair, or did the owner get left paying for a problem that should have been covered? In Part 1, we start diagnosing this dead Taycan and quickly find the first issue: the 12V lithium battery has shut itself down. But that is only the beginning. After scanning the vehicle, the real problem starts pointing towards the high-voltage traction battery. One cell reading inside module 26 appears to be almost zero volts, and that one tiny reading is enough to stop the whole Porsche from operating. So the high-voltage battery has to come out. In this episode, we remove the Porsche Taycan battery, open the 79kWh battery pack, fight through the factory sealing silicone, and begin the difficult process of finding the faulty module. This is only Part 1. The repair gets much deeper in the next episode, where more faults appear and the job becomes bigger than expected. Insurance rejection or unfair treatment? You decide.
