Hi folks - my 03 TD4 was belching out buckets of black smoke under heavy booting and was running lumpy. Got a mafam and senser from roveron and fitted them. Cleaned PCV assembly and fitted new wool filter. Took off EGR cleaned gunk out ( loads of it ) refitted EGR. Performance is better, running is smoother ( can hear turbo at last ) but in 1st and second gear under good throttle freebie is still leaving clouds of junk behind it. Should I disable EGR and fit new PCV assembly - any ideas out there ??
