Hi all,

Have a tdv8 that I purchased recently.

When I bought it and ran a diagnostic it had the error code exhaust gas recirculation sensor c circuit low.

The car has 114k 3.6tdv8 (2010)

Local reputable company near me called midlandremap are quoting me £150 for EGR delete and a map out... States they would delete the EGR in the closed position.

Is it worth doing?

Yes. Physical and electronic delete needed which I think they’re suggesting Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

i would go for it .......that is a very good price .if i was close i would take mine in to get done

Thanks guys, I spoke to them and they don't put blanking plates on... Just ag EGR delete. Is it still worth doing?

if it was me i would….still think it is a good price

The EGR system is there for various reasons.
It's to do with getting the engine (or some components) temperature down under certain circumstances.

I've read quite a lot about it and decided to leave it on and functioning.
I also run a Vivaro van which has its EGR working and it has been working fine the past 266000kms.

It does benefit from "clearing the system" as I call it which is a good run down the motorway.

If it gets "deleted in one form or another your car might fail its MOT ?

Engaging in illegal EGR removal or other emissions control system tampering in the UK can result in various penalties, including:

Fines and penalties from regulatory authorities.
The vehicle was declared unroadworthy and impounded.
Invalidated insurance coverage.
Increased emissions lead to environmental harm.
Negative impact on resale value. 2018 SE SDV8 4.4 Byron Blue

I blanked the EGR on mine at ~150k miles. Straight away it idled better, the tip-in response improved (when you initially open the throttle) and MPG improved by a small amount.

And the biggest improvement is oil stays cleaner for longer.

I suspect if I’d cleaned the intake out I’d see further improvements on the first bits too.

Irrespective of the legality or performance changes ( good or bad) the EGR valves on the 3.6 engine have a nasty habit of failing and parts being sucked into the turbo and possibly the engine so for this reason alone it probably worth doing. I'd physicaly blank them as these older EGR valves have been known ( on other cars at least) to stick open so a software delete alone won't help you. Blanking kits are cheap to buy and if you have a GAP IID tool you can buy a software update to do the software delet yourself. 2012 TDV8 Vogue (L322)

Not on a 3.6. Thinks that's required on the 4.4TDv8 Paul,

Just out of interest, do these go through the MOT OK?  “If it ain’t broke, don’t fix it” -where’s the fun in that?

Yes they do Got - 2017 SDV8 Autobiography in Loire Blue
