I had a similar prob on my ZT 2.0 CDTI failing to start when hot. Turned out to be one particular injector which showed poor leakback on test with another failing marginally. I had all 4x injectors serviced and balanced by Lynx Diesels and the transformation was impressive. Now starts on the button in all conditions and massively improved mpg

great job frank! i appreciate you for all what i have learned from you .. good luck

excellent presentation,,,,

Keep it coming sir. Thanks for the vid.

Thoroughly enjoyed. Many thanks for sharing Frank.

spot on! A pro in the trade. Please try when the engine this hot. I've found a injector to fail under these conditions

@MasterTechDiag I agree, like benkinsella said below, look at obd mode 2 freeze frame data.

Great video as usual. But I was a little surpised to hear the conclusion: - "we have to wait for whatever it is is wrong with this car to occur"; - "continue testing until such time as the vehicle cuts out"; - "I will attempt to find out if there's anything that perhaps relevant to the vehicle not starting". Isn't that what OBD mode $02 (freeze frame data) is for?

Can you help me to change a relay on a rover 75 its for my neihgbour

I see you dont answer the questions but i hope this time you do, i have a problem with a vw touran 2.0 tdi 2007, this one only when its cold doesnt start if you let it still for 4 days or so if you turn it on every day it starts right away otherwise you must start it with starting fluid, thank you very much!!!

Did you ever find out what the problem was? My 75 has the same fault.

Did you ever find out what the problem was?

audio is OFF, really decrease the quality of the video
