Is this normal?

When I remove oil cap , engine running it's hissing and wants suck oil cap ?

Only issue is , at idle after a minute or so , the car throws out blue smoke when you accelerate , nothing in morning on cold start or any other time , only after idling a couple minutes , it throws blue then after that it won't do it until ,it's idling again.

either valve stem seals ( but in that case it would burn oil constantly), PCV valve has a problem or you have (a) wornout piston ring(s) or your turbo seal is starting to leak... in all cases take it to a mechanic to make sure what the the actual problem is... (ps could also be misfiring when at idle because of a bad coilpack or a bad sparkplug but this should leave at a faultcode in the ecu)

Update , it's more of a greyish smoke no miss fires no fault codes , oil after about 800+ miles topped up around 200ml roughly , Audi said nothing wrong so taking to another Audi dealership this week , I showed this video to some on the forum and was told it could be too much vaccum.....it's had new plugs a few months ago at Audi.

to much vacuum is pointing towards a pvc problem.

The upload file does not have an allowed extension.
That's the message I get when trying upload a video

At my 2nd Audi dealership and they said pcv is normal , and they don't know what the fault is.
Great extended warranty that is , probably keep running it until it gets worse , one guy said probably opf which I know it can't be , that normally raises the rpm to regen , and opf there to run clean , not smoke after idling !

New update.....2nd dealership have now found something and want car for 2 days investigate.
Oil pooling in the exhaust was his find.
Now want car for 2 days to see if it's pcv or turbo or something else
