I had an interesting fault with my epic equiped mk5,it stopped dead no dash lights nothing. Checked all the small fuses in hope all good. Tried to remove what appeared to be a stuffed fusesable link. Broke that . Disconnected the battery cleaned already clean posts bodged up the fuseable link with a bit wire and the bloody thing started. I don't think it was the fuseable link was it disconnecting the battery reset the computer. We have similar problems with hgv auto shift gearbox not shifting, turning the power off resets the computer and its all good
