Hello,

I have a 2007 307sw HDI model with 1.6l engine and have an issue with an injector leak. I can see where the diesel is leaking out at the base of the injector furthest to the right.

I noticed this a while back and didn't have any issues until recently when I would start it in the morning, it wouldn't stay idling and when I would push the accelerator it would die. Also lots of white smoke out of the tailpipe and a little from the injector area. Usually after about 10 mins of trying to get it started it would start up as usual. This would happen about once per week.

Now, I can't get it to start at all and suspect that the injector seal needs to be replaced?

I was going to look at it myself, but got all the way until the last 2 allen bolts holding in the injector and it won't come out. There are still 2 Torx type bolts there, but it looks like these are not holding it down? I didn't force it and just left as is, still not sure how to remove it completely.

Also, would the injector leak cause a "Depollution" error?

Thanks!

If you undo the 2 torx type studs (E6 socket) they help to pull the injector out, I doubt the leak would cause a de pollution fault but you never know with the 1.6 hdi. A session on pp2000 is needed really, if you post your location someone might have pp2000 near you.

Well a good trick to help remove an injector is to actually start the engine, let it run and undo the bolt holding the faulty injector by half a turn and let the pressure of the firing cylinder help push the injector up and out and just keep repeating until its ready to be removed by tool.

Think I read that on here somewhere :thumb:

Of course you have to have it running for this to help.

Thanks for the help guys!

Would an injector that leaks at the base be the cause of the engine not staying running and dying out? Or am I looking at a bad injector that needs a replacement?
