How does a failed glow plug affect how the engine runs on a journey with the 1.6?

On modern diesel engines the glow plugs are not only used for starting the engine. The glow plugs are also used during normal operation and driving. The reason of this is to make the engine run smoother and reduce emissions.
A defect of the glow plug system should generate DTC codes. Volvo and Ford Tdci will cause limp mode with failure of the glow plug |

I don't see it as being an effective measure as glow plugs take time to heat up and therefore have an effect on emissions, also if the engine efficiency is dropping to the point where it doesn't have enough residual heat to efficiently fire the next cycles charge, it pionts to a design fault. More voodoo to hide the fact that diesel is a dirty fuel!

I have glow plug connector issues, I have also had incorrect plugs installed, thread not in the correct place thus the tips not reaching the required position and Ive not had any plug related Vida codes show up...

Yours is a bit bigger than a 1.6 though. Seems from the comments above this problem is mainly with the 1.6 engine, possibly the 2.0 as well but not sure.

If anything, i would have thought it would show in Vida on mine more than the P1 seen as its a later setup

I'd make a guess that with the smaller engine, at low speed/load it doesn't create enough heat to maintain an efficient burn but yours being bigger does. Like i said, a design fault, overcome with a bodge to try and alter the Laws of Physics and/or Chemistry to try and pull the emissions back into line.

Regarding glow plugs , yes you have the idea . They are not likely to fail shorted . more likely open circuit . but see what the resistance is ...
