Slow start-up when warm, glow plug issue?!

[Lockstock]

Hi

My A4 b7 2.0tdi starts up every time when cold, but when warm it takes three to four seconds to 'fire up' - to start.

I wait for the glow plug light to go out on the dash every time but always a delayed start......any clues?

Is this likely to be a glow plug issue?

with thanks

as far as i know its the other way round with glow plugs. if its faulty it will hesitate to start when cold. I think you might have an air sensor issue possibly? hook it up to a diagnostic machine

Hey H-M3.
I've bought a cheap reader-so I will def get it plugged in to see, do you know codes? I will put it into search engine to see what comes back.
Thanks for your time H-M3!!
Regards.
