The Tdi300 is simple and cheap to repair (spares) the Td5 it is more complicated and expensive and I cannot afford it. I do not want the same experience with the VW van if I choose wrong.
I know very little about land rovers except I was told once that one model/s had unit injectors that cost around $1000 ea.
A quick overview of the T4. Production started in 1990 & was probably sold in OZ in around 1992. One of the engines sold in OZ was the 5 cyl.2.4 diesel using indirect injection with a Bosch VE style pump. These were sold [in OZ] until 2000 when they were replaced with the 2.5TDI. This engine was released in Europe in'96 & was taken from the Audi range but took a while to get here. This engine is direct injection but mostly old school with the exception of the fuel pump that has another " layer inside" that receives inputs from the ECU that is now fitted. This engine compared with it's predecessor is powerful but very economical. The T5s are more powerful again [but probably not more economical] but have unit injectors & the oil required is special [more expensive]
Hope this helps your decision making.
Understand how it works, troubleshoot logically BEFORE replacing parts.
