HELP HELP HELP - Glowplug Wiring Harness?????

[Warrenmole]

Not having much luck....having had the emmisions warning light on with glowplug 3 error..I had the garage change the 4 glowplugs and reset the light, now 2 days go past and the light is back on, took it back and still says the same thing even though they were replaced...garage say it's probably the wiring harness...any ideas how much this will be...don't want to throw anymore money down the pan only for it to be something else..

A bit more information would help...

What engine etc?
What glowplugs have they fitted?

And any garage that says 'probably' in any of their recommendations 'probably' doesn't know what their on about.

It is quite common for garages to fit the wrong glowplugs which then damages the glowplug controller. What fault code have you got.

[Warrenmole]

sorry for the delay. ok the fault code is 17057, the garage assure me they fitted the correct glowplugs so don't know what to do now.???

17057
P0673
Glow Plug/Heater Cylinder 3 (Q12) circuit, electrical Fault in Circuit


I would want to check the exact make of glow plug. Garages often fit the wrong ones. Other than that, there must be a fault in the wiring.

thanks, if it is the wiring where would i get it and how much would it roughly be???
