16619 -Engine boost condition - Limit not reached. Check intake hoses/ connections for leaks. Check Turbo charger waste gate regulating valve/ waste gate working correctly. Must move freely when accelerating, won't achieve full boost if waste gate sticking open. Check Turbo impeller turning freely, oil feed pipe for turbo can get blocked causing impeller to seize. Engine compact, not easy to access these components.

Check wire harness between driver door and body for broken wires.Wire harness bends , when door opens and closes so it may brake the wire or two inside harness.

hi, if you still have time to take it back to the dealer. take it to them.

They usually have igniters that will start to give out on the light bulbs. But if they did not find any faults then it would require a long diagnosis time.

oil type is either 5W-30W or 10W-30W depending how cold your climate is, as far as having the car properly taken care of, the Audi dealer is the best option, they have all the proper tools and service info needed to keep the car in top running condition.
