Glow plug warning light flashing for 20 seconds after starting. Recently changed glow plugs. Anyone know if the system needs reset. Plugged in code reader and coming up with no faults. Thanks

1.9 multijet engine. 56 plate. Disconnect the battery help?

check battery condition first, then check plugs (how are you checking the glow plugs?)

One of my plugs was faulty. Checked resistance. Changed all four due too good price. Just needing to get the light out now, didnt know if there was a certain way of doing it

i had the same problem on mine. get your 'earth wire' from the battery checked, mine had corroded on my 58 plate dynamic and a auto eletrician came and shown me and fitted it, it was messing up the system sending out stupid warnings luckily i managed to get the money back for my glow plugs before i fitted them, get it checked though!
