golf mk3 tdi 1996 glow light flashing.

[samgti]

Hi there,my golf's glow light starts flashing 20 minutes after start up.
Otherwise the car operates normaly.
when glow light starts to flash if i restart the car it will disappier for a cycle of 20 min.
Has anyone had this problem befor?I was thinking maybe the glows need replacing,but i dont know if its been done before.
It has done 275"000 kms and has been a good reliable runaround since i've 75000 kms on it.
it's stock standardand only has a 3"down pipe stright threw no muffler,with a performance tunning box.
I've taken that out for a day but the light still flashes
any ideas whay this is hapenning?
thank you all.

sorry mate, no idea... the glo circuit is controlled by temp sensors and a couple of other htings - maybe you have a temp sensor on the way out? hard to say.... also, there is a timing circuit built into the glow plug relay circuit, maybe theres a fault there.

either way, a scan with VAGCOM may be able to detect a fault somewhere. GolfLoon may be able to help you out.

Thanks mate.
i've spoken with golf loon today,he rekon we change the glow plugs,and if not there is a sort of warming thing up the streem which might be cousing it to be changed.would it be ok to drive a couple of days?
im so stuck with work,work and work,looking forward for fixing it,befor gets worse.thank you for recomendation.
I think i need to do a vagcom,i dont know if golf loon doese that at the moment,i'll call him tomorrow to find out,he is always helpfull.
if not,is this a volkswagen dealer thing,to be over charged?
anyone with a vagcom,or trouble shooting?
thank you all.

We have VAGCom mate. It wont answer all questions, but may help.

the glow light is not flashing for past 2 days.
i have replaiced the rear brake fuse,probably got nothing to do with it.
the only thing i can think of,is that for the first time,i've filled up the tank
to the neck no air remaining,was a mistake,maybe that was a reason for it
i dont know,but so far no light flashing
i'll let know what i'll experience,might come handy for someone
in the future,but so far i think,the neck filling of the tank have coused it?
maybe.
thank you all.

i wouldnt think so. more likely it is an electrical fault that is intermittent in nature. you may find it reappears again sooner or later.

glow plugs can be a little inconsistnet as they begin to die, sometimes they work better than other times.

good luck

i'll replace the glow plugs,if the light come's on
once again.
