     Your service manager sounds right on track to me. The thermostat swap is
a popular "adjustment" on VWs, but shouldn't be needed if your car is in the
proper temp range for the driving you do. His info also lines up with the
specs in my Bentley manual. The stock thermostat opens at 189'F, which would
indicate a 190' unit. Stock is always preferred, unless you NEED to go to
another temp range.
