To sum up he talking out of his ar*e
There are no electrics on a 300 Tdi No engine of car managerment ones anyway.
The only electrics going to the engine are the heater plugs (Which you don't need anyway) the alternator, the injection pump, and the temp gauge. Thats it so what is he going on about. If you start a Tdi and take the battery off it will still run so it does not even rely on its electrics to run
He is getting confused with the range rover of the same year. Now there are the ones to steer clear of
The Tdi Disco are some of the most reliable cars that land rover have ever made
