Blocking the EGR Valve

[foggs]

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

I've had it blocked for over a year now and unfortunately nothing I've tried has helped, it will come up regularly. I've noticed it pops up mostly when I put it under load, but I have a bluetooth OBDII, so it's a matter of pressing a few buttons on my deck to clear the codes. It's a bit annoying at times but you get used to it I might get fed up one day and put a hole in it, but for now deep breaths

HAHA thanks foggs. I was told i could chuck a hole in mine and that "may" help. I've seen a broken wire can also be an issue, but i am uncertain if the guy had a year the same as mine. Just one of a few things i'll check out.

I might be blocking mine this weekend. No one knows how often the warning light comes on as it seems to be different for each vehicle. I plan on seeing how often the light comes on. If it's frequently I'll just leave the light on and clear it on weekends or whenever I can be bothered.

Does anyone know if you can use the Torque app to clear the code??? I have that app on my phone, it's a bit cheaper than a Scanguage ;-)

Has not bee a problem helping mate..
Pretty sure yours is a Di so is a little different to my crd.
The hole in the egr plate does stop the egr code. @TPC had a hole in his. Pretty sure it's about 8mm.

If its a direct injection motor. Never.
If its a Common rail. How long is a piece of string? Each motor is different in the CRD's in reacting with a full plate. Best thing to do is just put in a full plate, if you get the CEL come up, drill a 8mm hole in the centre of the plate. But then your egr is not fully blocked, but its better than nothing. What the egr does to the intake system and motor, I personally would put up with the CEL coming up.

Oh not doubting you at all champ. I'm just the sort of person to try and get all the info i can on thisngs and go from there. Drilling a hole is still definitiely an option

Glad we got the boost limp issue sorted.. Atleast the car is drivable now

Yes you can use Torque or DashCommander to read and clear the codes. They also give you a description of the code, so you don't have to guess.
I use one of these with Torque, found on ebay..
