Thread: EGR eradication confusion RRS 2007 TDV8 3.6l

Fitting the blanking plates and cutting off the the inlet butterfly as well as the software was the instructions. Maybe the software doesn't stop things working, just stops errors after you fit blanking, but that's just a wild guess. You could confirm with BAS if the physical blanking is still required.

I contacted Pete, at BAS, and unless your egr is sticking open with errors, the software patch is all you need to disable egr function.

The issue on some vehicles was that the EGR had already failed and as such then needed to be blanked, often if the EGR is still functioning you can just turn them off in the ECU.

But that's just my understanding.

I have just had mine done last week. There was an error on one of the valves but this has since been cleared along with a remap done on a dyno. The valves have been programmed to stay closed and also physically locked.

Yes, it does run much better, but I'm not sure how much is contributed to the remap. It is nice to not have the engine light on though!

Pre remap 195Kw and 617Nm

Post remap 226Kw and 715Nm

I can not first hand confirm that. I was advised by my competent Inde that would be the case and I went with that.

My brother blanked his MY08 TDV8 RRS after performance issues pointed to a leaking EGR valve. The electrical connectors are still fitted and the pcm is original. The RRS is used almost entirely to tow his van and has had no issues since blanking the EGRs.

Hey Graeme, I was curious where you wrote about your Brother Blanking off his EGR.

And wanted to ask, did he just simply remove the EGR link up pipes on both sides, Blank them with plates. And start the car and Drive...
And whether he has had any lights on the dash or codes since..

There doesn't seem to be a definitive answer on the internet anywhere, if this is a possibility on a Sport 3.6 TDV8.
So many conflicting reports about , "yes you can" , "no you cant" Having to tune it out .

Just looking for someone who has first hand knowledge of someone having done it , with no ongoing issues...

Thanks mate.. Regards Marty.

He inserted plates at the valve outlets - the pipes are still fitted.
No faults or messages are displayed with his stock ecu. Note that L322 and RRS fault handling for this engine are not necessarily the same.
