A bad injector would also cause smoke. Ask me how I know.........

EGR's were out for years before they introduced DPF's.

I had a Diesel Vauxhall Astra of 1992 vintage that had an EGR valve fitted so they have been out for a long time.

On many cars, disabling the egr is as simple as unplugging it,
Yes, a pretty red light will show on your display, but everything else will continue to run smoothly.

I'm pretty sure my 08 b9 has a egr but no dpf as it has no eloys.
My 03 vivaro definitely has a egr but no dpf fitted.

Won't unplugging a component like the EGR valve make the system set a default map?

Yes, on some cars unplugging the egr will trigger limp mode, but there are plenty where the eml will show up, but without any other faults. In such cases the car will continue to drive normally apart from the red eml glowing in your face.

Problem is, if another unrelated fault shows up later that would normally trigger the eml, you may have no way of telling because the eml is already on.

Unplugging the EGR valve on certain Renaults results in the vehicle driving as normal (if not better) with no warning lights, but the downside is the fuel consumption increases dramatically despite what the fuel consumption computer may say!
