After reading all the horror stories of injector fails and the costs of replacement i was regretting buying my 2007 tdi sport. After reading that VW where replacing these for free i decided to ring VWCS and see what they said. I must advise that i havent suffered injector failure. I explained my concern and the lady i spoke advised if my car had the faulty injectors all 4 and the wiring loom would be installed FOC. The lady transfered me to my local VW dealership and they booked it in for next Tuesday with a free courtesy car for the day thrown in.
