Injector failure?

Some advice please ....OK so having made the decision to sort out my Dispatch, cam belt, front breaks and new alternator... today I get a call from the garage to say they think an injector has failed. I have no idea what to do. They say it's difficult to work out which injector has failed. Can any one on here help. I had a quick look and they seem REALLY expensive!

Re: Injector failure?

What is happening for them to be suspicious that you have a failed injector.....
Is it missing.......
Unlike the HDI  where you can do a leak off test in situ........ DW8's type of injectors all normally have to come out and go on a flow bench  and Usually a new set of nozzles can effect a cure

Re: Injector failure?

The 1.9 uses a mechanical injection system , so to find out which injector has failed  simply loosen the 17mm injector pipe union (nut) on each injector until it doesn't run any worse. That injector is the duff one. . Its like pulling  plug leads off ....... the cylinder with the duff plug  doesnt run any worse when you take the lead off.  A diesel specialist will rebuild the injector for a more reasonable price than buying a new one.
