Just a quickie... Can anyone confirm the following codes are glow plug codes...

P05658

P05659

P05660

P05661

Just did a quick scan with my handheld scanner and they all came up but with no details.

If they are glowplug codes then it probably explains the intermittent hesitant starting we've been experiencing from time to time.

Also am I right in thinking glowplugs should return a resistance of about 1 ohm if good

You can check easily if the glow plugs are ok.

Take of the cables to the glow plugs, take a cable/wire and connect it to + from battery and put the other end to the glow plug. If there is a spark, then the glow plug should be ok. If not, it is dead.

PS: Be very carefull not to touch with the cable the engine block, etc.
