EGR Insufficient flow problem

Hi andy-fisher,

Bit of an old thread I know but I have been following your admirably tenacious thread re: poor EGR flow as I have had exactly the same problem with my Octavia. Including limp mode, which I seem to have sorted with the help of fuel tank additives and driving in low gears like a lunatic to burn off all the coke in the air intake and EGR system.

Anyway today I fitted a £20 vacuum solenoid sourced from "our best friend" Ebay and BINGO! So far and touch wood the dreaded light has not reappeared!

One thing I noticed on the old Vac unit I took out is that two of the ports on it seem to be full of "soot", each port has a little filter doesn't it, could these choked up little filters be that problem?

If I CBA and assuming the fix is indeed permanent I may just clean the filters and re-fit the unit to see?

So I took a piccy of the old vacuum vac unit, the photo vaguely shows the blackness of the gunk in the filters of the two right hand ports on the shot.

So Andy in anticipation of the dreaded light not re-appearing, sincere thanks,

John.
