Thanks again for the feedback lads. I did some reading over the last few days, and have come to the conclusion that I'm going to keep it in good order, and leave it in place. I'm doing an oil change tomorrow night, so while I'm at it, I'll be hauling apart the egr "system" (such as it is) and giving it a good carb-cleaner-dunking...

The results of my reading have convinced me that blanking the egr can possibly lead to increased engine temps, since the egr "gas" (at risk of redundancy) lower combustion temps, if I am to understand correctly.
