There's a slight leak as shown in the photo. I'm guessing there's a slight hole in the pipe or something? Anyway, can somebody get me a part number and price for it? Not sure off hand which injector it is (I think it's the third one). Or where I can I buy some generic braided pipe from?
give it a good clean and check again to see if you can narrow down exactly where the leak is coming from
My old peugeot did this. Sorted for not much at all, ask for diesel spill off pipe at your local motor parts place and pull off the old pipes and replace with the new.
