Also note that you will probably have a G70 crankshaft sensor fault, which will most likely be due to trying to start it over and over (dont overlook it) but just make sure it's not logged because you've been trying to crank it so long, as opposed to it actually being faulty.

i hope it is not the flywheel :( i don't have a scanner to check for codes. any other symptoms i should look for to confirm the flywheel is to blame?

Not really, if you absolutely cannot fault the issue (i.e: using logistic diagnosis and ruled out every possibility) then it's time to pull the gearbox and check the flywheel by hand for excessive movement..

Not to sure of anyone in Sydney, sorry. But don't be scared just yet, get a logical diagnosis going, it could be something simple. I am just advising on the DSG flywheel possibility because I have seen them cause this issue many times before, this does not mean this is your issue, just a possibility. Remove the gearbox to check the flywheel as a last resort :).

thanks for you help. will keep it as a last resort.

Please keep us posted on your progress, i have had this problem for as long as i can remember, i am going to do my glow plugs then maybe look at cleaning the starter. Good luck :-)

I have a feeling it is related to the starter and diesel injection. Just a hunch as it does everything else perfectly. I think it is starving of fuel due to the low crank rpm of the starter which i have read is a common problem when it is worn down. I think it could also be related to the injectors, they may be dirty.

Production Automotive on Batt St in Penrith - I take my Polo there to get serviced, they are VW specialists.

Thanks Luke, Know about them from my air cooled vehicles. I did not know that they did watercooleds as well.
