After recieving some invaluable information from this forum this week I have sorted my issues and thought i should share with you lot.
Anyway, if you are unaware there are issues with the injectors on the mk5 gt tdi 170 and the passat 140 PD, the issue is the injectors are faulty and they fail anytime, when they do it's scary, the engine completely shuts down and you loose the steering etc.
Other than the danger, the cost is ridiculous. I had one done and it cost me £950 at an indepandent dealer, VW would want over £1100 i'm sure! Usually when the injector goes the wiring harness goes too adding to the cost.
VW are aware of the issue but are NOT recalling the cars affected, instead they are sorting issues that come to them, don't go to your dealer, some are unaware of the issues, ring customer services, the number is 0800 0833 920, have your chassis number ready etc and they will bring up your details.
Explain the issues and they will ask you to book your car in at your dealer, they will then replace the intectors free of charge.
I managed to get the other 3 faulty injectors sorted and i'm getting refunded the money i spent getting the other one done too.
Hope this helps
Should be nice and easy for the search function too!
Thanks
