[REV335]

For people looking for the EGR Delete pipe found this on ebay>>>

http://www.ebay.co.uk/itm/ALLARD-BMW...item27dec1ba51


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

[GreekboyD]

This will only work on European models.

[REV335]

Do you have different EGR systems over there as well?

[Poosik]

does the ebay pipe allow the exhaust gas to recirculate? i dont see a plate/obstruction internally..

[dixy2k]

maybe TDI can chime in since he knows this part very well.

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

TDI
could you please tell us again how and if you got rid of the faulty code regarding the EGR block?

[dixy2k]

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

2nd round of remap with Ecotune.

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

[J. Dub]

So, what's the consensus? For us USA n54 engines?

Mine harness is disconnected, and EGR temp sensor with egr cooler is in the shed, no issues at all after tuning.

[Lexx.md]

I am reading comments and it looks like there is a mess.

In US EGR has electric actuator to get feedback from the valve and make it harder to block.
In EU you just pool a vacuum tube and block it and EGR is not working.

The part in the subject is meant to replace the EGR valve body, so by the eye it looks like the same as we have, and it makes sens to install it only if you have EGR coded out.

And there are different topics where me and other people were showing how we deal with our EGR's.

Agreed. As time progressed and some tuning options emerged that could deal with the US EGR system, this became a valid approach. With Jarek's remap I was able to do as you describe above. I think there's quite a few of us doing the no EGR cooler option now.

I hadn't come to that conclusion. Perhaps you're better informed from PM traffic. I only know of around a few. I run a stainless steel coolant bypass though some have found that this flow path can be deleted. I run about 85°C when fully warmed up.

I for one really like being able to put the catch can where the cooler used to be. I'm in the minority of not worrying about can and piping not freezing. My inlet/outlets are about 10" each with a 90° elbow in the middle of each run.

I worked around the EGR limp mode issue by modifying the valve actuator like so:

335D EGR Valve Motor

It's still connected and works, just doesn't do anything anymore.

Freezing what? Air or oil?

I have catch can in place of EGR cooler.
IN couple month will open it and will see what is in there.

The image is not loading.
But doesn't it throw any codes at all?

Water vapor is one of the constituents of the stuff coming out of CCV system. I do remember you going coolerless now, Lexx. Thanks for reminder.
