Mine FAILED 6 months after mods. Usual DPF removed , EGR mapped out plus F1 map at one of the reputable places.
First result: mean of 3.68 l/m after 6 accelarations, second 3.58 l/m.
This is a 57 2.4 jtdm 35,000 miles, problem appears to be a lot of commutes, not enough italian tune ups! Was advised to give it a good clear out so did 20 miles at full bore in third gear (rev limiter = 81 mph), back to the station and straight on the test machine. Result = pass at 2.73 l/m which is still v.high. Not been back to discuss with tune up place yet as garage is too far away for casually dropping in. Still - was a bit upset!
As for smoke I get a swirling puff on hard accel from 1000 /1500 rpm. Then it will be clear for a week! Was also told a dirty inlet throttle body can give problems. Maybe I have other problems!!!
