Hi all. I've seen a couple of threads mention that those with a ZD30 and have put the EGR plate in get a check engine light. I also am having this just recently. When i got the car no issue, MAF dided, i put a non-genuine one in then a month later i had engine lights and limp mode. Have since adjusted my dawes valve because and bout a proper MAF, no more limp mode but i still get the light. Checked the code by bridging pins and it says EGR control valve failure or malfunction. I have cleared the codes several times but it just comes back. Any thoughts? at a guess i'd say the plate has no hole in it.
been talking to bigguwesty and he has been helpful, just thought i'd ask around some more also

TIA
