Hi all, I have a problem with my Focus (2002 TDCi) which I would appreciate some help with. Sometimes, after driving for 5 or 10 minutes, the glow plug indicator light on the dashboard starts flashing and the engine suffers a reduction in power. If I restart the car, the problem goes away.

According the manual, "if the light flashes when driving, it indicates a malfunction". I'd like to know if this means a problem with the glow plugs (i.e. one or more need replacing) or something else altogether. My understanding of the glow plugs is that they are only used when the car is started, after that they are not used. This makes me think that something else is wrong.

I'd appreciate any suggestions, especially from others who have had the same experience.

Thanks,

Ross

MY mate has a mercedes c class had a similar problem

we thought like you the glow plugs only work before starting

On the mercedes they thay have 2 stages one for starting then when running they come on again untill the car warms up (to do with the emiisions) they keep the manifold warm

his car had a fault on the control unit so they were not comming on after the car had started same sort of warning light

we could not understand why the glow plugs came on the car started OK then the warning light came on after it was running

may be the Focus has similar system some one may know more than me

Could be a few things. If it has a fuel filter with only 2 pipes and an electrical sensor it is most likely the fuel filter needs changing. But if they flash and the enging stops it is something more serious. One point here though, before you take it to get the diagnostic code read, make sure the fault warning light is on. Normally the fault has to occur twice before it will lock in an error code!

the glow plug light covers many issus...it is an indicator that you have a problem.Idealy it should go to a dealer with the correct IDS equipment for accurate diagnosis.YYou ned to go to a dealership at some point to cler the fault codes and havethe light put out.

Could be the Mass Air Flow sensor. The best way to find out is get a laptop diagnostic.
