egr delete

Yeah been thinking about the effect on the dpf theyre dodgy at the best of times.
My egr is playing up so i thought a delete may be an option.
Also with the full delete you run the risk of a runaway engine I believe. Whilst you can stall it in 6th gear, it's probably not very nice to have it happen lol!
Have you considered just getting a replacement gasket which limits the gas rather than completely blocking it? No ECU issues I believe then. Few people on here have done it.

Yeah iv seen the gasket mod in another post.But there is something wrong somewhare the egr is opening and colsing at idle causing rough idle.Iv cleaned the egr and it seems to work fine but I think there is something telling the egr to open when it shouldnt.
Nobody has as far as im aware, myself and BIGG Addicted have looked at it a few times. Motorsport version with no ASV but i need it mapping out and because my ECU is locked because Custom Code decided they didnt want anybody copying their DPF code it means they want to charge me extra to map it out...like h3ll im paying extra
I might just fit it and drive around with warning light on! Car runs alot better with the Gasket mod fitted. i scanned my car yesterday tho and it had an error code stored for Insuficient flow of EGR Valve

I have the Allards EGR delete pipe fitted (the shorter one which keeps the OEM ASV), can runs nicely but does have constant MIL on the dash due to communications failure with the EGR. I suppose had I kept the original EGR I could have still had it wired up but not connected to the inlet, which would have got around the MIL.
I have had DPF delete so can't comment on whether that would cause any issues with regen etc.
I decided against the gasket mod as my EGR got complete coked up and the valve broke open, causing a non start and also my inlet manifold was also full of soot. My thinking is the gasket mod would not stop this and eventually would probably end up getting blocked and causing MIL light anyway.

Any Noticed improvement on this mate? Is it just a simple case of removing the old one and fitting the new one? Non wiring needed to be chopped or pipes needed blocking?
Im still unsure if to go down the non-motorsport route or to go the full motorsport route and remove the ASV

Slightly better throttle response, but I don't know whether it's the EGR or the fact I cleaned the inlet out.
Fitting the pipe itself is easy (3 bolts) but the gasket required to block the feed hole in the exhaust is a real faff as a lot of extras (airbox, pipes etc) need to be removed to give access. No wiring needs cutting as you remove the multiplug from the EGR. I covers the end of mine with insulating tape and cable tied it so it doesn't rattle around.
I now have peace of mind that my EGR won't kill itself again, my engine is running purely on clean air.
I decided against the motorsport one as I couldn't work out how the engine would turn off without the ASV. (I'm sure someone will now point out something obvious)
Just need JBS to come up with a map to get rid of the MIL!

Nope never had a light, i did however have an error code stored in ecu when i scanned the other day to say "restricted egr flow"
nothing to worry about tho of course its restricted
hmmmm im intrigued, can someone shed some more light on what exactly this does and can i fit one to my CR? I had heard about EGR valves before but i thought that was to stop all the jerkyness of the PD caused by the ECU?

To keep emissions down the EGR valve diverts some exhaust gasses back through the inlet. This only happens under certain engine loads, eg light load at 50-70mph. If anything it would cause the engine to run a bit lumpy as the purity of inlet air is reduced by the introduction of exhaust gasses.
The gasket mod simply introduces a smaller diameter gap in the EGR feed from the exhaust to reduce the amount of "dirty" air being fed back into the inlet, whilst this does not completely remove the "dirty" air the benefit is the MIL does not come on.
The EGR delete pipe replaces the valve and completely eliminates "dirty" air being introduced into the inlet but does cause the MIL to come on as the ECU can't communicate with the EGR. Fitting this part does not cause any problems with the running of the engine.
I've not had a proper look at the CR engine so wouldn't like to say whether they would fit your engine.
HTH
well this gasket mod sounds like a good idea, and im always one for bolting more bits onto my car.
where can i get one?

It's a VAG part so any dealer should be able to help you. I've done a quick search and found part number for the gasket is 028131547B.
EGR Looks to be in the same place as the PD Engines, You see that Black pipe coming off engine with two torx bolts holding it on, that needs to be undone, remove the old gasket and fit the new gasket there
See my Picture below you will get the idea

I've just installed my own electronic flap, which I had initially wanted to add for runaway / shutdown, but as it is rather slow to close, it's there just for run away now. I have a lambda O2 spacer and the EGR and stock flap still hooked up and hanging in the breeze until I can come up with a simulator / tune workaround. I still get the insufficent EGR flow cel every few days, then clear it, but it eventually pops back up. The full story is in my tinker thread in members cars, recently updated for the last several months!
I am still running the stock ECU and DPF, and interestingly the first DPF regen without the stock flap failed due to insufficient airflow past the MAF ( the flap part closes to reduce inlet air and drive up the required heat, and in doing so increases MAF airflow speed significantly ), but a second forced one with my custom flap part closed completed perfectly. I aim to get the delete tune, but like Andrew above have wanted the EGR and stock flap tuned out as well, and thus far CCode haven't been interested in talking to me, despite an exceptional local distributor down here. Pity as I champion them so despite the fobbing off I copped.
The car is quite different even on the stock ECU tune and exhaust, far more response, seems a fair bit fatter in the mid range, and the biggest thing is it now feels smooth, whereas before I figure the flap and EGR were causing both restriction, and a lot of the hesitation and jerkiness especially on light throttle transitions, such as cresting a hill. It feels like a different car, can't wait to get her tuned!
