Hi,

I'm running a 156 20v 2.4 JTD and have just taken off the EGR for a clean and notice that it has a blanking plate instead of the normal cut away rectangle, but it has 4 circles (8mm ish) cut away in the corners. Should I put this one back on or the new fully open one?

Regards
Dave

No, that's a modified blanking plate that offers a better solution to the common egr issues many have. Leave it in place.;)

When cleaning egr's one extra thing that helps immensely at preventing further issues is to use a grinding and polishing bit on a multi tool like a dremel.
Once all the carbon deposits are cleaned off you then use the above items to smooth the rough inner surface of the valve itself to a shiny finish.
That way, the carbon has no rough casting finish to actually stick to so does exactly what it is supposed to, end up being burnt off via the compression process and out the exhaust.
It will take all of twenty minutes to smooth it all out, you don't need to go crazy but that time spent will pay for itself tenfold in eliminating future running issues and fuel savings;)

its been blanked of more than likely due to the fact the egr isnt working........its not just a case of cleaning them the solenoid needs to move open and close the valve, suspect it could have been blanked due to cost of buying a new one as its a dead cheap fix
