Loom will be about $300 Greg.
For those following this thread and also have a TDI, your VW may still be under warranty, even if over the 100000K. If you have a full service history with VW, they will, most likely, replace the Injectors under warranty. If not, you will have to fight like me. VW will replace the injectors for me but not the loom to the Injectors which had been first looked at (easily damaged when tested due to deterioration) by a non VW dealer mechanic. I am not 100% satisfied with this outcome, but close too. Just happy to get the car back after 5 weeks!
