thought i would report this, for any high mileage JTD doblos out there.
My dobby which i pay to have serviced properly failed its Mot last week on emissions at 100,000 miles. It got a 5.2 and over for smoke. (needs to be under 1.5 to pass)
I started taking the air intakes apart to remove the EGR valve and got a shock from all the oil and gunk in the air intake.. Like this (not my car)..
I never saw anything like this..as part of normal running. The EGR was stiff and full of carbon, but was fine after some WD40. took as much pipework as i could from intercooler to inlet manifold and removed all that gunk. Oil change, new filters and redex in fuel.
Then ReMOT and emissions now down to 0.4 . Drives much better now.
Its not on any of the service books or dealer information that the engine is gunking up like this. It should be part of the general information about the car. All that gunk has being getting pushed through the engine and must be having a detrimental effect.
Pretty stupid engineering. If the engine life is shortened then the cost of replacing the engine or entire vehicle prematurely causes more pollution than what the EGR saves about 10 times over.
