I have a 2005 Allroad 2.7T and the car starts right up first start. doesn't make any difference what time of day. If the car sits for about 1 hour or more it takes quite a few cranks before it will start. It does not indicate any codes when checked with Vag-Com. I did replace the CTS on chance this was the problem but it didn't fix the problem. I have checked the fuel pressure and check for bleeding injectors but all of it checks good per specs.
Is this maybe a fuel pump problem?

 

This maybe a long shot, but have you tried cleaning your MAF?

 

No but I will try that and post results.
Thanks.

 

Cleaned the MAF and this did not fix the issue of starting.
Looking into replaceing the Crankshaft Position Sensor.

 

Installed new wires and plug on CTS and tried new Crankshaft Position Sensor. Neither fixed the hard start when hot.
Anybody got suggestions as to what maybe the problem???

 

I'm interested in the resolution cuz I just purchased a 2000 A6 4.2 and has same problem. Seems not to be getting fuel after it's warm.

 

Still haven't solved the issue. My Allroad is a 2.7T.

 

I have the same problem, but the other way round.when i turn the key the glow plug light goes out straight away,and the car starts after about 8 seconds later.
but once it has started i have on problem starting it. i have a 2002 A6 allroad.can anyone help with this problem.
