EGR bypass poll following on from the black smoke thread
jnoshea:
Apologies to all TD5s. I didn't know if the EGR played a more integral role in the emissions control of the TD5 than it does on the 300Tdi so I didn't know if that would bias the poll (if the EGR couldn't be removed). Question obviously applies to TD5s too then.

Why are people disconnecting them? I thought they slightly improved emissions? I could probably answer this by checking previous threads but I'm playing catch-up on thousands of threads :oops:

Dave,
You'll probably find that the actuator has packed up. I had one do that.
As for why, just disconnect the EGR valve from the inlet manifold and take a look inside. If yours is anything like mine was, it'll be full of oily gunk. With the EGR blanked off your car will only be sucking in clean air. Yes, the EGR does reduce NOx emissions, but as they aren't part of the MOT, who cares? It's probably something they had to do for the US market.
Jake:
I blanked mine and put a straight pipe from the inter cooler to the turbo
:D
ChrisW:
I clicked on what's an EGR because I haven't got or have never had one :D
(and it's a 300!)
nzoliver:
:o
Well, I have blanked mine where the pipe meets the valve inlet but left the connections alone.
