The 3.0l V6 tractor is the same lump as used in the VW Touareg and probably has the same reliability as a business colleagues. All I can do is recount his problems and wish you the best of luck on reliability and running costs.

He has spent in the last few months £1,200 on new DPF and has now got a common worn / leaking injectors problem and has been quoted a mere £3,200 by his local VAG garage to replace them.

Trying to help him out, the cheapest I could find for geniune Bosch injectors was £295 each, but he has managed to get 6 second hand for £100 each, so still with fitting an £800 repair bill. Suspect it will be HPFP next, but I think he hopes to have got rid of it by then!

Apparently they use Piezo injectors and not solenoid ones and they are not very reliable. Current thoughts are that any fuel contamination damages the ceramic discs within the injectors. Water contamination is meant to be especially bad as this turns to steam through heat and pressure at the injector ceramic discs and shatters them, the particles damage the injectors, the discs don't seal so they leak and the return pipe contains ceramic particles which through the return pipe, end up going through the HPFP to damage that. So you are looking at a an £1,800 plus bill if you source new injectors and change the injectors yourself and probably also looking at needing a new HPFP at £800.

£3,800 buys an LPG kit and an awful lot of LPG!
