Diesel Emmissions
Hi
Got a K reg 1.9td and its putting out 3.5 on the emmissions test, any hints on how to get this down?

Dom besides the oil change, "italian tune up" and new air filters it may be worth taking the car for long drive before the test to ensure the engine is hot.
As well as using the injector cleaner in the fuel tank, it might be worth trying this: fill up the filter housing half full with neat injector cleaner and crank the engine over a few times. Leave for a 5-10 mins then start it and take it for italian tune up.
If after all of those its still goosed you are left with blanking the EGR off or more serious works like someone has said injectors changing or Adjusting the timing.
Hope you get it sorted.

As it is a turbo diesel, a quick temporary way to reduce the maximum fueling is to disconnect the pipe from the intercooler to the injection pump (you would need to disguise this!).
However, the Italian method almost always works. The Smoke Test is little more than a measure of the accumulated soot since the car was last on sustained full throttle. Just floor the pedal for several bursts in first and second until there is no more soot left in the silencer.

Remember guys : air filters dont influence the "richness" of air/fuel mixture on diesels.
They only restrict more or less air admission to the engine, which in turn restricts max fuel volume from the diesel pump, which in turn restricts max power from the engine
Because there is no such thing as an air/fuel mix on a diesel engine

Run it on Tesco Rapeseed oil for a while, take advantage of the warmer (although wet) weather we've been having.
