So in my efforts to unlock the mysteries that surround the TDCi 2005 Mondeo I have come to the conclusion that the only thing left on the car that I haven't pulled apart yet are the injectors.

Has anyone done it themselves? (I guess so) and how big a job is it? Do I need specialist tools?

I'm reasonably handy, but don't want to make more of a pickle of the tank sounding Mondeo than it already is.

A bit of History. So far....

  • Its had a full change of filters oil, fuel, air along with new oil of course
  • Blanked the EGR off with a plate at the EGR end - cleaned the EGR anyway
  • Changed the oil cooler and the main cooler Stat - Still runs really cold, we have two mondeos and one runs at normal temp so this is suspect
  • Checked every Turbo pipe and oil/water pipe for leaks
  • No Smoke (since EGR frig) but there was a lot pre this
  • New Clutch

The things I found wrong

  • Using a cut out bit of tin from a sweet box to block the EGR has limited use - £4 for Ebay and its a lot better
  • When looking at the injectors one was coded incorrectly - I used Formidable to change this, checked and it had gone back to the incorrect one. I did it again and it reads correct now

No Errors on the Diags - even down to not showing that the EGR has been blocked

Is there a Wiki on how to get them out and clean them? Thinking of buying an ultrasonic cleaner from Aldi for 20 quid.. any use?

My aldi has no stock left. Not sure if they are considered powerful enough. Have a look at Peter's how to on his sig for details on the "how to"....

I think physically not that hard. If you disassemble, clean, reassemble with original parts then c2i should still be relevant. I suppose Changing bits, not sure how much is luck- all depends on how close replacement parts are to original and which parts affect c2i - I'd have thought potentially all. Suspect that if they are very bad, or possibly just full of muck, then likely to be an improvement even if c2i not still technically correct - but see Peter's guide for better info.

I used an air line and took my time and lots of care as there small springs within the injector and make sure u put back right way u can clean with clean deisel as well but no wire brushes or scotch pads to be used on any part what so ever in side the valves I used where Delphi code for them is 28239295 and it's worth changing the nozzles as well

Thank you for all these and especially for the "make your own leak off test kit" which is where I'm going to start. Lack of dosh is the main factor on not taking the blue car of woe to the garage.

Hi Garry,

When changing injectors it's best to just do one at a time and restart the engine after each change. This reduces the chance of a car that won't start because of air in the fuel lines.
