Hi all. This might just be me. I've had my 2002 406 for 2 years now with no problems so far but as of late it's started to taken just a fraction longer turning over before it starts. I thought maybe glow plugs, then when I start reading about them there's not a lot in the user manual. When I turn on the ignition the glow plug light does not come on, then someone told me that unless the temp is at a certain level then they don't come on, but I would have thought that the dash should at least light up to let you know they are working even if they don't heat up. Is this correct, and if it is, is there any way for me to test them just so I know that they will work when they're needed. Thanks in advance.

that would be because the hdi engine does not need glow plugs for starting until about -20c

hdi engine taking longer to start could mean the following
bad battery or earth connection
bad starter connection
bad battery
bad starter

Starter or bad injector assuming battery is good bad starters are common now due to age.

If it runs fine once started then i would replace the starter they get old and slow with time fine in summer struggle in winter.

Thanks

Thanks for that people. Sounds like that unless you actually do a physical electrical test then you're not likely to know if they're working or not. I would have thought -20 was a tad too cold, if it gets that cold here I won't be going out of the house to test it that's for sure..

ALL modern diesels will start without glowplugs some do not even have any ! its due to the way fuel is injected an easy test would be to unplug the glowplug relay it WILL still start.
