EGR Emulators

Hi That's right, after the clean cycle the valves are closed.

The input cable to the emulator is disconnected from the valve and plugged into the emulator, so there is no way that the valve can open as it has no power?

yes, EGRs closed with engine off. Emulators plug and play with no need to remove butterfly or use blanking plates.

More can go wrong with airflow on the sequential turbo engines due to the use of an inlet isolation valve so more checking is appropriate, as well as more detailed checking that EGR is operating as expected.

Graeme you know your stuff. The TDV8 is as you say happy with the emulators and doesn't look for those air quantity changes.

The D3 went through a phase of trying different emission control routines in 2007-2008 and then from 2008 onward, reverted back to the early type of setup and even the D4 2.7 runs great on the emulators.

I had briefly looked at developing an EGR emulator myself but apart from having my hands full with LLAMS and my normal work, the lack of access to appropriate diagnostic equipment meant that it was never going to happen. I started a project to integrate my boom-spray controller's section switches with my tractor's after-market auto-steer system via its canbus, but that's not likely to happen either having not progressed the project in the last 3 years.

Hi Andrew I'm very interested in your product for my 3.6 tdv8. I'm happen to be cleaning my intake and egrs at the moment. Egrs are surprisingly clean but the intake was full of goo. To repeat what has been said before the goo looks to be a result of the egr carbon and diesel mixing. The car had been running fine the reason I'm cleaning is I've had the intake of to replace the thermostat housing. I'm sure as can be seen from the pic of sensor and throttle it must be having a negative impact. I'm surprised the egr flow into the manifold is pointed towards the throttle against the intake air flow.

As can be seen the egr protrudes into the intake, with your product do you think there is a problem if I cut the egr pipes to be flush with the manifold so not to affect/restrict airflow?

Also this butterfly valve under the manifold that has been discussed, I'm not sure what it does, is that of any benefit? Can that removed/closed with the emulators.

As I have it all apart noes the time to do it.

Like they say a little bit of knowledge is dangerous.

And can I pick up your product as I'm in Perth.

Cheers Paul

Another pic to justify disabling egrs

Hi Paul,
Ive sent you a PM.

Thanks, Mark

Is checking whether the EGRs are closing properly difficult (or secret squirrel), or does it require the emulators to be installed first? Cheers
