Glow plug light flashing

[Jordan20vt]

My glowplug light is flashing!! I've just been out for a drive and it was flashing for about 15mins then went off! i'm pretty sure this has nothing to do with pre heating as all of these lights have double meaning

Is this something obvious or coluld it mean multiple things?

Thanks for your Help

erm not sure matey, have you tried the search button?

 

[gazjones]

was going to say glow plugs on 20vt i know your not meant to start the engine till the light goes out so looks like its not warming the cylinders up enough so light is staying on. or there is a problem somwhere electrically

Check your brake lights!

 

[Jordan20vt]

Thanks, checked that was aware it could be pedal switch but they are working, there is no obvous misfire in the engine either.

Hmm had this on my 1.4 PD Arosa but only flashed when it wouldn't start! Problem was the Glow plug relay in the end but this meant it wouldn't start on very cold mornings. Maybe its related!?

It has another meaning when it flashes though. If it stayed on you'd be spot on there mr jones.

possibly the cars fine though, but it has just gone into the minuses today i suppose

It could be a minor electrical glitch somewhere. Best get the ECU scanned to see what fault codes are triggering the warning.

 

[basstard]

yeah you need a scan, if it's not the brake lights or switch then it could be a lot of other things,,,

Jordan not seen u in aggggggggges matey!

Yeah to echo what ppl have said, its usually an electrical fault to do with the Cruise/Traction conrol and Braking system. Mine came on when the 2 filaments fused in a stop and tail bulb and know that brake switches can cause it too.

Theres sometimes an error logged in our ABS controller.

You goin to any shows this year than, like spring festival again!?

 

[basstard]

shouldn't an abs fault trigger the abs light??

i had the same on mine.
glow pug light flashing on, stopping on for some time then going off, & then re- appearing.
i got stopped yesterday, bye police, glow plug light was flashing, but my brake lights where on all the time, & he said it might cause a accident, can i get them checked.
car went into seat today & the brake light switch is faulty, so had it done under warrenty.

 

[basstard]

btw, if you do a scan with vag-com, if there has been a brake light switch failure even for one second, it will show.

 

[Triple D]

ah well, looks like his dad will have to pay for it then, as its a 53 or 03 plate iirc, and has no warranty left

The flashing glowplug light is, quite commonly, an indicator of a brake light or brake switch problem. Before doing a scan, just check the switch for normal operation. And if it needs to be replaced, the part is very cheap. It could even be covered by a recall or extended warranty.

Mine did this this morning, so vag com'd it tonight and it came up with this code.

2 Faults Found:
19586 - EGR System Regulation Range Exceeded
P3130 - 35-10 - - - Intermittent
16955 - Brake Switch (F): Implausible Signal
P0571 - 35-00 - -

VAG-COM Version: Release 311.2-N

prob the brake light switch
it is a double switch that turns on the brake lights and also sends a signal to the ecu to tell it that the pedal has been pressed

lots of things need to happen in order to keep the emissions under control and keep the engine revs correct during heavy braking

just change it, it's about 8 quid

Nope, think it will be a trip to the dealers for me then as its still under warranty. Would this likely to happen after having brakes chaged? as i had new discs and pads all round on saturday.
