I attempted this today, but a 22mm Welch plug is too small:

I think a 24mm one would work well, but I'll report back!

Also have this plate but finally decided to get rid off it and you can disable (not completely) EGR through DIS software. Job for 5mins and clean job.

Makes me happy :D

Egr Restrictor how to

Post by jason@bwchiptune » Mon Sep 25, 2017 8:43 pm

The best way to keep the egr closed
is to set it to closed all the time in the ecus software when doing a remap
If this is done the correct way the dpf will still regen on cars fitted with a dpf system

Most people use a solder ring version. I think either would be ok though, that hole in the side of the ERG Body is tapered.

We can program the dde so the the egr will stay closed all the time

This will keep the intake manifold clean and reduce the wear on the swirflaps

By yourself BMW allow to restrict EGR in DIS, as i remember in older ISTA ( in new this function is blocked) or in some android apps. Egr will work but it will be closed faster. Something like cooper ring, but with sofware. If you want to remove it you have to go to tuner. I like android app from Polish forum BTOOL.One user wrote it and he upgrade it all the time. It was developed to monitor and force DPF regeneration. Now it delete errors, show life data, you can write liva data into file, show like injector works in diesel and monitor DPF regeneration or force car to do it now. You can also register battery, if you use battery with same parameters, restrict EGR working. Autor of this app is adding more functions, but after work when he has free time. It also works with petrol cars, but i have only diesel in my garage, so do not now what you can do. App works perfect.
Free version of BTOOL LITE to try it if it works with your obd plug official
