Thread: EGR Emulators

Blanking EGR should mildly increase temperatures at low throttle openings...
Less air, less bang, less heat..

At higher throttle and speeds it could add heat if stuck open as more fuel from more throttle is applied to make the power needed to maintain higher speeds.

Blanking them will remove this issue..

I have MY13 TDV6
About four weeks ago after I clean throttle body I blank left EGR valve pipe with shim- 50% less . Car runs fine, no messages or faults. But i am not sure if ECU will adjust fuel mix, or temperature potential problems.

Part blanking is not more effective than leaving it open.. gasses and contamination will still pass through.

What if i close one or both sides 100% without remapping ECU.

You will get a fault

As I understood the workshop, they blanked the EGR's at manifold and removed them, so no coolant running through them as they are "dissapeared".
(not sure what they did with the coolant hoses)
They fitted emulators to keep the ECU happy, and to be sure the vehicle starts/runs.
Seems a couple of others who have had same engine change with EGR removal/blank were surprised at drop in temperature also.
At first thought they might have left the Territory sensor in, but they used the LR sensor off old motor.
Temp gauge reads in usual position when on open road, just reads much cooler when in slow traffic.

The cooling system is designed to ensure a minimum operating temperature. If it's not maintaining that temperature then I would suspect either a faulty thermostat or the hoses have not been refitted correctly.

Any one have any further update or progress/info on gallys emulators .
