Do you have air re-circulation switched on? That would cause condensation problems.

Thank but mine looks like th pollen filter - touch wood, its been ok since changing.

I'm new to Audi ownership but regularly cleaned out the EGR value on my mk5 888 Astra.

I'd get YouTube searching on how to change the EGR value before handing over that kinda cash! EGR exchange took 15mins to swap out on my old mk5 Astra!!!!

i soaked my EGR value, and I mean soak the EGR value on the first clean, then went to town with a pipe cleaner/toothbrush. You need to clean as much as you can..doing just on the outside surface of the EGR value will not fix the issue.  You need spend about 60mins on that first clean, if youre done in 5mins, you're not Cleaned it enough...

good luck..

It's unusual that no error code comes up, but does sometime happen....

EGR VALUE on my old Astra showed this symptom but not sure if you've got an EGR on your 1.6 petrol.... 

Immobile misbehaving (transponder starting to fail) could also give these symptom but you'd usually get a imobilizer error message on attempting restart... 

Poor compression could give you issues with starting up and poor running but is rarely intermittent ....

interrmittent issues with no fault code are a Bain to troubleshoot...sorry!

Assume car is well serviced, reputable garage?

Update

drain plugs are clear, draining freely..still no sign of the source....

Only made short journey today.  Let's see if it behaves on my long run tomorrow!!!

thanks again...

Hi Folks

few week into my A3 8p ownership and I notice there is a lot, and I mean a lot of condensation inside the cabin during normal driving...but no signs of water ingress (no damp patches)

im going to check the bulk head drain plugs tomorrow...

I'm also going to have a look at the driver door seal and the rear wiper boot seals..

Are there any other common causes of excessive condensation in the A3's?

Mine was sounding similar, asked the garage to have a look at it when they did the last belt change...

they coudnt replicate post belt change and put the noise down to the old tensioners / pullies (I had them replaced during the belt chance...)

just incase...
