1.9TDI Emissions Workshop - Fails to start

[SkodaJoseph]

Hi All,

I have a mk1 superb with 350000km on the clock. Usually took a few turns over to start but I shut it off one day and it will not start. Emissions workshop has been showing for a while with cel and coil light. Got a scan done today, I attached the results. Any help / advice appreciated. Thanks in advance.

Have you load tested the battery? They can cause issues as they get weaker, get the correct spec battery from a decent manufacturer if it needs replacing.

Test the glow plugs if they haven't been done they will need replacing.

Test the output of the alternator to make sure it is charging the battery as it should, pay particular attention to the alternator clutch pulley as they usually only last 60-80k miles and will take out the drive belt tensioner if they fail, if the tensioner if hopping a lot a idle that will be a sign its on its way out.
