It's a shame elsawin no longer exists otherwise you could print off the exact paperwork to prove the garage wrong.
If the parts manager says that ETKA lists the car for as it left the factory then you need to ask him why it updates - my print screen previously posted shows both 5w-30 and 0w-30 but now only lists 5w-30 - the new LL oil standards.
Notice how it does list non-long life oils but they are greyed out - this is because they are deprecated and are no longer to be used - this is the proof that the dealership are wrong!
Like I say it's an older print screen so currently ETKA only lists 504 oil which is the 5w-30 on the print screen and the 0w-30 is 503 and is now not to be used. If you need to see it more clearly then try this link:

ETKA does not list just factory configuration - it is the VW system for identifying authorised parts and that includes consumables such as oil.
Name and shame.
I'd also get on to VW CS and make more of this, they simply should not be using the wrong oil, it's a basic error!
