I would use the recommended 507 spec for the car as its made for that engine - the properties of the 502 spec oil are not made for your car but an older generation of VW engines.
If down the track you need to say top up the vehicle with oil the 502 would be ok (only as a top up in an emergency).
Saying the above though I would use the factory spec all the time, if it were my car & it was still under warranty.
