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 ??

Hi
Might be a bit off topic but how do I get the EGR lose and do I need to take of the inlet manifold ass well and clean all of it?
And does anybody have the part number for the EGR?
Any help or advice would be appreciated.
I did go to roverron's webpage but I'm stil not to sure what to do....

Check that the turbo's variable nozzle actuator and linkage is not stiff or jammed.
I've heard of the actuator having to be changed (though some dealers have been known to replace the turbo instead only to find it was still the same!!)
Finally, check for splits in the intercooler hoses and leaks in the seals at the intercooler connectons.

Madalan, don't know what the hose is called, but if you look under the bonet on your LHS you'll see a large diameter hose going from the engine. if you look under this pipe it could've perished, that's what happened to me and all it took was a replacement hose and the problem was solved. Hope this helps you.
Thanks for the info-I will try to get some access to the turbo - are there any clear signs of what Im looking for . Checked my intercooler hoses - they are both intact and LHS one was replaced at last service coz it was wearing thru where it brushes against a screw head underneath hose - great bit of design that one !!! Intercooler hoses are very oily inside though - is this normal or is there an underlying problem?
