Had a letter from VOSA requesting me to book my 2005 (55) 140k Passat TDI into my local VW dealer to have the injectors replaced FOC.

Called them last week, took the car in yesterday 16th April, was told I would get a call when work has been done, later that day got a call to say they was having trouble matching the injectors to the control unit and they will need to fit another set, so car wont be ready until today.

Had a phone call earlier saying the injectors have been replaced but the car is very slugish!, he asked if the car was like this before I took it in, as they seem to think there is a problem with the turbo. I explained the car was fine before going into the garage, so he said they will have a look at it again tomorrow?.

Where do I stand regarding this, as the car was fine before being recalled in to the dealer and now there seems to be a problem with the turbo.
