Help Smokey JTD - Not the turbo hose...

Hi all,

I've noticed that on acceleration (not necessarily hard acceleration) I get a plume of black smoke out of the 147 (JTD 8v). Having read all the similar threads on this it seemed the Turbo to Intercooler pipe would be to blame, but it's not - the guy at the local alfa specialist had a good look on ramps and said it appears fine. I've just had the 48k mile service carried out (hoping this might solve the problem) but it hasn't.

Any other ideas?

MPG has reduced slightly since the start of the problem (from avg 51 to 46) if that helps to diagnose it?

Any help appreciated...

You tried any fuel additives? Might just need a clean out.

did he remove the pipes to check them or just by eye often it is not until you take the hoses off that you will see the damage could also be the intercooler split

Put some Forte through it, if that doesnt solve it check vacuum pipe to the actuator(pull it off and suck). if not check the egr valve.
