Smoking on the motorway

Hi all

Had the van a good few weeks now and around town it’s great. Just had a trip on the motorway and noticed a decent bit of smoke. It happens when I’ve been off the accelerator then give it some herbs again. So that’s riding 5th gear down a hill or same if I dip the clutch and let her idle.

Soon as I hit the gas again there’s a puff of smoke, then she’s fine again.

She’s a 2004 1.9 non turbo

Any thoughts?

Cheers!!

Cheap option first. Take the EGR out and clean it as well as the intake manifold. My thinking is as the EGR allegedly only works in low revs and when you de accelerate or just start to give it beans again it opens and spits through all the built up carbon shit. This gets regurgitated through the engine giving you a big puff of soot.

Thanks Casper, sounds like a good first option. What you’ve described is very much in line with the symptoms. I’ll give it a shot.

Cheers

I’ve got the 1.9 non turbo

Only on Friday did I finally get around to doing anything. Took Casper’s advice and looked at the EGR.

Step one to to follow a previous thread and block the inlets to the solenoid.  Five minutes later took her for a run and couldn’t believe the difference! No smoke at all and non of the annoying kangaroo hopping at low revs!

Happy days
