The glow plug light is showing after engine start on my 52 Multipla 1.9 JTD.

I saw this guide for the stilo http://www.fiatforum.com/stilo-guides/151734-dealing-preheat-fault-message-stilo-jtd.html

I have check the resistance from plug that goes to the glow plug relay heater and pin 2 is open. Would this mean that the glow plug in cylinder 3 is faulty (as per the stilo guide) or could it be a different cylinder on the Multipla?

T.I.A for any assistance.

you can tell by the wire colour. (if its cyl 1 then let garage do it unless your good with the tools)

I'm going to let the garage to do it but wanted to tell them which plug to change. I took a note of the pin, but didn't note the colour. If nobody's sure which pin 2 is i'll take take it apart and check the colour.

For what it's worth the glow plug could be fine. Mine has been showing this for a year now, but I thought I'd wait till cold weather when it actually started making a difference. -5 the other day and started on the button . A friendly mechanic has advised me that the sensors on fiats fail more often than the things they're checking. Born out but the fact that we periodically get a humidity in fuel filter warning, but having had a garage (non Fiat) drain it they said it was perfect. Along with the eroneous air bag warning (don't get me started on that :bang I can only conclude that most lights on Fiat Dash are connected to a random number generator

If you can live with your Multi being lit up like a Christmas Tree (very festive) it appears that the best way of diagnosing true faults on them is wait till something won't work.

eh?

You are aware that theses 'failing fiat sensors' are mainly made by bosch and fitted to most cars universally not just Fiat. I think your friendly mechanic is talking a little rubbish here!
