I would be very interested to see your comaprison between the manifolds. Check to see if the ports match the gasket. The one I saw on the net had the EGR port coming off cylinder one only. Having less exhaust gas in the intake tract is not ideal for emissions, but I am not sure what effect there is on partial throttle tune. Closed or Full throttle will be unaffected.

I'm already bypassing the egr. That was the first thing I tried when I first noticed some exhaust smell.
Can't notice any difference in driving with the egr bypassed, except less hesitation when taking off.
I'm not 100% sure it is the manifold , but everyone says they crack, a mech told me he'd never seen one that didn't have at least a few cracks...
It could be the turbo, I noticed one morning what looked like a stream of exhaust coming out from my front right hand wheel arch whilst I was waiting to turn right, but then it disappeared later...
I've changed the air cleaner element, and are going to replace the breather , just got to find an E-torx socket to get it off, never seen one like it before.
If I have to remove the intake , I'll do it, but I've read the injectors can weld themselves in and be hell to remove.
I'll remove the covers, air cleaner etc, and then go underneath, after I find a cast iron manifold...
