An accumulation of dust inside the body of the turn signal switch can cause a partially closed circuit, which results in the turn signal relay intermittently clicking at a high rate. Spraying a small amount of residue-free electronic contact cleaner (such as Electrosolve) inside the turn signal switch can resolve this problem. The turn signal relay is not the root cause of this problem, but may be damaged by it.
Vehicles with 2.0L engines consume oil at an unusually high rate. VW specifies the oil consumption should not be a cause for concern unless it exceeds 1 quart per 1000 miles.
