Diagnostics - injector fault

Postby bm525 » Sat, 30 Mar 2013 10:14:39 UTC

Hi all. Would diagnostics tell me which injector is at fault? Anyone? Puff of white-blueish smoke goes out when start from cold. Injector/s? Which one? Just to have them checked costs about £40 each. And then 2nd hand injectors are £60 each. Don't want to replace all six as it may only be one at fault. Car starts fine. HELP

Over fuelling on a diesel (leaky injector) gives black/grey smoke I believe, so "white-blueish" sounds more like oil.

It sounds like oil? What with it? Had it changed. Car does not burn oil at all. When its stationary for more than 24 hours I am having hard time trying to start it. Then when its finally starts it sounds like bag of s...t! Give it 30 seconds and its settles smoke is gone and car is fine again. I think its injector/s. Thanx for all guys

+1

Sounds like one or more injectors.
Maybe you could start by running an additive to clean the injectors.
But most likely you will have to replace the faulty ones.

Eternal diesel problem.

Happy Easter.

Trouble codes?

Injector correctional values don't tell anything about injector leak off. Leak off is what matters when we talk about starting characteristics. Leak off has to be measured manually, can be done with injectors in place.
