Glow plug light not lighting up - Welshy_Pete - 21-07-2013 My Peugeot 306 hdi 1999 during the winter and cold times the glow plug light used to come on. But since the weather warmed up I've not seen it on for awhile now. The car starts and drives fine no problems. I was thinking the same why the light stopped coming on maybe the warmer weather. I worked out today why the glow plug light wasn't coming on anymore. It had nothing to do with the warm weather. I checked the bulb in the dash it was fine. There just afew screws holding the dash dials in place. So then I checked the relay at the back of the battery below the ecu and black box. I removed the 10mm nut to remove the glow plug relay black box with green on the bottom. The connections were dirty and a bit corroded up. There 2 connections three 10mm nuts one 8mm nut. But there all on the two connections. There also a plug socket as well which I cleaned up as well. So I cleaned everything with wd40 and a wire brush. Then wd40 again after it was all clean to soak and leave on. The glow plug light now comes on even in the warm hot weather. So the glow plug light is ment to come on. I can even hear the glow plug relay click now as well. RE: Glow plug light not lighting up - Welshy_Pete - 24-07-2013 The problem back again its stopped lighting up again the glow plug light. I even checked the bulb a second time. Also tried 2 other glow plug relays making no difference. The strange thing the white wire going in to the relay contact. The metal part with the thread on used to push in and out. The other 2 relays don't so it must of been broken then worked again strange then packed up after cleaning it. I'm just wandering what else could this be the temp sensor? Whats the black box with 2 green with relays next to the glow plug relay? Also anymore idea's? thanks RE: Glow plug light not lighting up - Piggy - 24-07-2013 fuse?!? RE: Glow plug light not lighting up - titch - 24-07-2013 What fuse is it for the glow plugs? RE: Glow plug light not lighting up - Piggy - 24-07-2013 would think it be in the underbonnet fuse panel as it would need to be a hefty ine RE: Glow plug light not lighting up - Welshy_Pete - 25-07-2013 Checked all the fuses under the bonnet and in the car there all fine. I even try swapping over the temp sensor no difference. Tried 2 different glow plug relays. RE: Glow plug light not lighting up - Piggy - 25-07-2013 check all the connections...maybe dodgy wire RE: Glow plug light not lighting up - Welshy_Pete - 26-07-2013 The light come on this morning when the engine was cold. But after hasn't come on with driving around places. RE: Glow plug light not lighting up - Welshy_Pete - 27-07-2013 The weather cooler now the temp dropped now. The hot weather the glow plug light doesn't come on. But soon as the weather cooler it comes on all the time. So this is normal I have found out its all controlled with the temp.
