Just bought a 2.2 TDCi, possible problem?
Posted 06 December 2009 - 04:06 PM
After lots of looking around I finally got myself an 05 2.2 TDCi with 77K on the clock. The car has all the stamps in the book etc. and drives beautifully, very powerful and pulls like a train. So far so good.
However, I went to start the car this morning and it misfired terribly for a few seconds, there was a lot of smoke but it cleared once the engine settled down. I only drive it for a few yards to move it on the drive, when I restarted again an hour or two later there was still some smoke but it wasn't too bad.
When starting yesterday after it had only stood a short while there was no problem.
Is this something that can just happen as a TDCi quirk or do I have an issue?
Fuel economy on a fast motorway run home and with some town driving was 40mpg (actual) so not too bad, although I was hoping for more and was planning to change the MAF anyway.
Any advice appreciated!

This causes a lumpy idle and smoking. Mine had the same symptoms except the smoking and it was air in the fuel filter. If it is smoking I suggest that its probably the injectors leaking.
This does not automatically indicate a problem. Many people on here have this issue and have just learnt to live with it

I think I'll focus on sorting the MAF for now as it's bound to want replacing, I guess I can't easily blank the EGR off though due to it being a later model.

Take the EGR valve off and give it a good clean. I got my mondeo with 37k miles on it and it was manky. Also remove the inlet manifold and clean that also (the also get manky).
Your running problems may also be EGR related, the valve may be stuck open

I think mine may actually be hidden under all of the engine cover!

That thread shows where it is and what it looks like. If yours is a Euro 4 facelift it will be the vacuum operated unit with sensor like mine.
You can blank it off, however the engine management light will stay on and unfortunately at this point there is no fix for this

As you can see, the airflow is quite restricted through there, and the valve can also get stuck open which results in poor starting and black smoke when starting and generally accelerating hard.
My inlet manifold was also in a right state so I cleaned the whole lot and noticed the car started better and got better MPG. I also noticed an improvement in performance.
I last cleaned it out at 45k miles, at 54500 miles now so will probs have another look mid 60,000

I'll see what difference a MAF, Manifold and EGR clean makes!

I've got the eBay Â£50 diagnostic lead and this actually gives live date for EGR flow si I might experiment a bit with the hole size in the EGR blanking plate but even with a 5mm hole I still got sooty deposits on both sides of the blanking plate and already starting to coat the valve body, pity really as it definately ran better with it fitted.

Teflon coating needed for EGR and inlet manifold.
