you will need the light mapping out but does not affect the performance with dash light on.

Compared to the Europe version, the high
pressure EGR is equipped with the following
special features:
Electric EGR valve with positional feedback
Temperature sensor before high pressure
EGR valve
EGR cooler with bypass

Here's a VW TDI with a bad intake CBU. This guy performed an EGR valve and cooler delete. He got a "check engine" light on afterwards.
If it is a diesel it will be plagued by CBU.

No it stops it recirculating. So you don't get any of the gunk/carbon going back in the engine

The ebay part is meant for euromarket as it is actuated by vacuum. US version has an electrical actuation. But here's the question. If you have EGR coded out, does the ECU care if the EGR is connected up electrically anymore?

TDI, would mind disconnecting the EGR from harness and see if ECU cares? If it doesn't care, this is a another way to cork the system.

The only downfall is there is no way to connect the EGR cooler so that would have to be removed. I wouldn't want it hanging off the exhaust flange only, but that's me. So, exhaust flange would need to be corked too. Perhaps, with all of the other work it wouldn't be cost efficient to do this. I would not want it all shiny like that drawing attention to itself that it is not factory emission equipment. I'm thinking i would some how paint it/coat it to look the same as the throttle plate color.

It throws a large yellow half engine symbol and instant limp mode. Tried that last year when fussing around with ways to modify the EGR.

If you don't mind clearing codes and don't want to modify the EGR hardware, you can try this:

Live and learn. That Euro dummy EGR has no valve hardware blocking flow path. Just wondering if there are any appreciable gains if the US spec EGR's throat were modified to get rid of the actual shaft and boss of the exhaust gas injector?

Thanks TDI
