I own a 2010 Nissan Pathfinder 2.5DCi Tekna with 41,000 miles on the clock. Recently I've had an intermittent engine light come on - this has been diagnosed as P0744 Code. My local Nissan dealer has told me the car needs a new torque converter at a cost of £2500. The car may also need a new transmission control module (no cost for this yet) and they've charged me £50 for the pleasure of diagnosing this fault.

I've also had it confirmed by Nissan UK that it's nothing I've done to the car, it's a manufacturer’s defect. Surly on this basis they should replace the unit. Are manufacturers' parts not covered for up to 10 years?
