Rough Starting And Smokey

[kamifa]

I have a Mk3 2.0Tdci and I am having problems with starting the car. In the morning generally I can turn the car over and it will fire up no problem but is very errattic and lumpy for a short while. it usually sends out quite a bit of black smoke also. I initialy thought that there was a glow plug issue, so replaced the glow plugs and this revealed that one of the glow plugs was not working, in addition to this for good measure I replaced the fuel filter also just in case it was that. I thought this would have solved the problems but it did not. After the car has been run for a while, once you turn off the engine, the car does not start straight away and I find that i have to keep the starter turning over until it eventually catches, this usually results in a black cloud of smoke again. There is no loss of power from the car, however, I have had to recently replace the Turbo boost pipe as this was split. I have also just cleaned out the ERG valve as this was quite thick with carbon. I have also had the car on a diagnostic to see if there are any faults but nothing shows. i am confused and frustrated as the car once running is a cracker. can anybody please help?

HI

Did you manage to resolve this fault as I have a very similar issue with my Mk3 Mondeo.

Cheers

Yes I have identified the problem or should I say, I paid £100 to identify the problem via a Delphi testing bench.

The problem was the injectors failed the test on Idle, which explained the problems with the poor starting and the uneven running on idle. It was my worst fear as I now have to pay out around £500 for the injectors to be reconditioned, the upside is that because I am using the same guy who done the test, the testing fee has been reduced to £50 from £100. I have to say that the test was very impressive, the injectors are removed from the car and put on the testing bench, which is basically an engine set up. The machine is set off working and is brought up to 40 degrees C then they perform the tests. It was worth the test money to get the result. Now its just a case of stumping up the funds to sort the job out which will be done tomorrow.

Sorry its not better news!! Hope it helps
