Well after hearing and reading lots about the Land Rover Mild Hybrid DC converter failures today we joined the club and replaced our first one.
Massive back order issues with these. Our customer waited 2 weeks or so which we’re told is a good result right now.
Replacement involves dropping the 48v MHEV battery pack down, opening up, renew the converter and reassemble.
Online programming and updates follow, all done in house using JLRs systems. Then finally the vehicle is able to charge its 12v battery again.
