Hello all

Chassis no: WV1ZZZ2KZ7X020777

I have the above vehicle in the workshop at the moment, it has come in for bad starting. i carried out the basic checks first i.e. air in fuel system etc. and i have traced the fault to the glow plug control and it's a bit of a head scratcher.

if i go in to the Ecu with the KTS i can actuate the glowplug relay but they will not operate when the ign key is cycled. i suspected the coolant temp sensor but it appears ok also the fuel temp sensor if i disconnect both the fuel and coolant sensor the glow system will work.

if i look at live data the oil temp is about 12 deg c above the coolant and fuel temp. from the info i have the oil temp is taken from the oil level/temp unit in the sump is this a red herring or my fault i have checked the wiring to this component and also tried swapping it with a known good one. i am reluctant to send it to the dealer without doing my best. any ideas?
