2.2 D4D Emissions Creeping Up, 99K...

[2912pwil]

Just had my 2.2 D4D MoT, it passed - but the emission levels are creeping up. This notwithstanding this year (1st try) my running on the "expensive" Shell V-power diesel & doing an "italian tune-up" each week & the morning of the MoT (was that a good/bad idea??). So, OK for 12 months but...emissions have been creeping up each year...

If the emission levels creep over the limits is this a BIG, expensive, problem or are there fixes that can be tried?? Excuse my ignorance.. if this is a simple question...

99k, mixture of country roads but predominantly motorway cruising.

Regards & thanks in advance

im no expert on the diesel engine as mines a petrol but from reading a lot on this forum it might be worth running a can of the bg244 cleaner through with a full tank to clear out any rubbish its good stuff as i have used the petrol version and comes highly rated on these forums and it does a better job than other stuff like redex just a thought apart from fuel filter air filter etc are they all in good nick and i believe somthing called the egr valve can get blocked im sure you will get some expert advice on here

[+robster+]

check you inlet manifold for cokeing up if your due to clean the egr valve out

also a restricted air filter or intercooler or turbo not getting to max wastegate capacity can cause a bit of overfuelling black smoke.

has your car got a dpf?
