wildci Posted October 31, 2007 Report Share Posted October 31, 2007 iv'e got a clio 1.5 dci with a engine management/glowplug light on permanently. it is becoming increasingly difficult to start but runs fine afterwards. i thought i'd go for the easiest option and try the plugs. i connected a wire from the battery and touched each plug in turn but there wasn't a spark from any of them, which to me means they are not conducting anything. the engine has done 118000 miles. does anybody have any advice on my problem and does my simple test mean that the glowplugs are all duds. any advice appreciated Link to comment Share on other sites More sharing options...
cruiser647 Posted October 31, 2007 Report Share Posted October 31, 2007 Glowplugs don't spark, they warm up to create a certain temperature to help the diesel ignite without difficulty. The wife's old Clio 1.5 80 dCi had this prob, only when it was between 1 and 5 deg C. Anything out of this range, and the car started and ran fine. In that range, it would just sit and idle roughly unable to rev for about 30 seconds. After that........fine. Will ask her about it later, if I remember.

wildci Posted October 31, 2007 Author Report Share Posted October 31, 2007 I know they dont spark,i was refering to a spark between the wire and the top of the glowplug that would let me know that electricity was going through the plug. anyway thanks for the reply.
