EGR delete DIY?

Ah I see how that could be beneficial. I'm still pretty firm on the idea that an EGR is not a good idea. Unless there was some way of stopping all the soot from clogging everything. Exhaust is so dirty (sooty/gets on everything/makes everything filthy) im surprised anyone thought to run it back through the engine.

I don't ever. I just don't have the time to mess with the mech side of it now.

The soot isn't really the problem, it's that when it shares space with oily crank vapor, it makes high build asphalt coating.  With a good oil vapor separator, it would probably be trouble free for many years.
When you think about it, your nozzles, pistons, exhaust valves , and turbo are  exposed to soot all the time, some cakes on, then it burns off  no big deal.  When you tear down a good motor, there is still a 2 micron coat of soot on everything.

I hear that. But that's usually just blow-by and the oily cylinder walls collecting some soot. its not like a pipe that directly blows it into the intake runners (which like you say isn't dry air - its oil vapor).

If you want have your tuner delete the EGR valve duty cycle/ EGR valve monitoring from the software, mine did. I use TDtuning now. I had a Rocketchip before and that eliminated the EGR as well but not as well as my new tune....I still had to leave the N18 valve connected to keep my MIL off...then in an effort to clean up my bay and make more room I got a 20 ohm 10 watt ceramic coated resistor to fool the ECU into thinking the valve was still plugged in! I don't need that resistor now but already sold it to another TDI club member.

If you have an e-TDI and you don't have VCDS, you are in the dark.

Did you get your VCDS from ross-tech?  Can you change the new "feature" of the 2012 TDI to cut the engine injections when it thinks you're going to lug or stall the engine off the starting line? This really annoys me on my new TDI...

[8v-of-fury]

That seems like a stupid feature, also.. good to see you back ARB. Been a while.

Don't want to transform this from EGR delete to CR TDI discussion but

The only way I know of to do that is via tune, which I know Malone is doing it, not sure about the rest.

Yeah I'm hoping to go see Mark very soon. Turns out he lives down the road from me...

all i do is slip a bit of tin between the egr and the inlet man and that is it , the egr can still open but no exhaust gases can pass in to the inlet man

I haven't noticed much on the cyl walls.

This is before rinsing with kerosene.

With the colder mornings here (about 12-14C) I think the egr is running more often now and the car is rapidly getting poorer mileage. Only seeing about 850km to 55 litres now and that's about 80% highway driving to work.
I think what im going to do is make a car cover (so i can work in the rain) and set up a little table - i no longer have a garage - and just take it all apart and clean it all.
