Car is 1.9 TDI 130 on a 55 plate.

I am getting "emissions workshop" message displayed whenever I start my car. Checked the glow plugs and found 3 open cct or very high resistance so have replaced all 4. However this has not cured the problem. I am unsure exactly how the glow plugs should operate. I know that during start up they will not come on unless the temp is below +9c, but even above +9c will they come on for a short period of time once the engine is running to ensure that the diesel is being completely burnt during engine warming up? I have metered the power to the glow plugs and there is nothing at all before engine start or immediatly after the engine is running. What relay is used for the glowplugs and where is the fuse for glowplugs?

If the glow plugs are operating correctly do you have any ideas where to look next? Unfortunatly I do not have access to vagcom.

Thanks for taking the time to read this.

The flashing glowplug light is the engine management light on VAG diesels, it needs a scan I'm affraid, but check your brake lights first as the pedal switch is a known weakness on all VAG cars and will put this light on the dash.

Bought MAXSCAN VAG405 from Amazon. (£50 with postage. Dealer wanted to charge £40 just to read the error code!) Did a scan and fuel temp sensor showing as faulty, Looks like that is a common fault. Anyway reset error and message and light has gone out, so will see if it returns. Got another question, maybe I should start a new post. Question is car has done 136K and I have done all my own servicing on it since 10K apart from the cambelt changes which I've got the dealer to do, but I have never looked at the EGR valve. My driving is 95% motorway and I have not noticed anything amiss with the way the car runs tick over or moving and still returns around 48 - 50 mpg, but should I remove it and clean it or if no apparent problems leave it alone?

Thanks again for taking the time to read this.
