If you will cut out catalysator you will have to replace original measurement for catalysator with something... we call it 'flame retardant' I call it 'cheater' who is cheating lambda zonde! I have straight pipe there!

+1 on checking the thermostat and then once that's confirmed ok (or replaced) move on to EGR cleaning.

Thermostat can be easily checked on the BC (CC) display - menu number 6 will show KTEMP (Coolant Temp.) and on a 3.0d it should get up to 85C.-95C. when temp gauge reads 12 o'clock. If it struggles to get past about 65C.-70C. then the t'stat is shot.

Engine breather changed lately?

A faulty t'stat and a clogged EGR will affect consumption but not by 30% - I suspect you have other issues in there too..

If egr is full inside there should be huge smoke during throttle! What kind of smoke do you have?

Personal experience: don't run a diesel at idle from cold, especially not in winter.

These engines do not warm up very quickly - they have a big chunk of iron and all the specific heat capacity that goes with this. They also overfuel from idle, to try to get up to temperature quickly and get the exhaust system working properly.

Finally, if you have a Thermotop it will cut in and burn extra diesel to help overcome the slow warm up. Check for the exhaust under the car around the left front seat - you can often hear this assembly click as the metal warms up.

Summary: get in the car, if there's no "Pre-heating message" start up and drive off. No waiting :-)

Could be your intake manifold is coked to bits. The performance degrades slowly so you don't notice it.

Remove the map sensor (slowly and carefully) if it's got loads of crud on it then the rest of your intake will be the same.

Just FYI, I think the "clicking" sound you hear is the dosage pump that feeds diesel to the Thermotop (Webasto) heater - it's also under the left side and it clicks when running - slowly at first then faster and faster as the heater spools up to full power.
