2007 1.9TDI loss of engine power - beechtree
I have problem with engine loosing power/going flat. Occurs at unpredictable times-mostly when accelerating. Usually lasts from 30 seconds to one minute butr can sometimes last severla minutes especially when on motorway. Lifting foot totally off accelerator for 5-10 seconds can result in engine regaining power. Ends with lot of black smoke coming out of exhaust. Have driven VAG turbodiesels for many yearts. This is different from normal turbolag. Use normal forecourt diesel. Problem with fuel or air intake? Have heard that Passat TDIs can have this problem. All suggestions appreciated.

This should still be under warranty; what do the dealers say?

Have not got it to the dealer yet. But yes is under warranty. Was interested to know if this was a common problem with Passats.
