I have an 08 2.0cdti. I have had to replace 3 injectors at £600-£800 each. Apart from that its great.
Injectors are no more than £150
They will even take yr old ones
Off you for about £50
I had three quotes. I even bought two off a very good mate that runs a vehicle parts business meaning i had them at near to trade price. The ones for my van are not £150 and £50 part-x.
The old injectors were stuck as well.
