Is it manual or DSG?
Some people have complained of power loss cresting a hill. I think that is actually the same wording I wrote in the 2009-2010 Jetta TDI buying guide in the FAQ. The best hypothesis is that it's related to the EGR and emissions tuning. No it should not happen. It could be the intake manifold flap or exhaust pipe valve, fueling or EGR metering, or a combination of these. Please let us know if the dealer finds any error codes.
