I will make the same comment here that I made on the other Audi post. I would not run an API SM oil in a car that calls for ACEA A3 oil. Not sure if this car calls for 5W-40, but that is what I would use in this car.
If the owner keeps up with such an OCI, I predict that the engine will get significant varnish and the PCV system will clog, if it isn't already that way. The OCI I'd try is about 3200 miles with high quality synthetics.
