EGR blank and new MOT rules

Hi all, thinking of getting an EGR blank for my Freelander 2 2010 but a little concerned with the new rules, will it pass or fail if I fit one.

Suggest you read the EGR Blanking Mod thread. Plenty peeps, myself included, who’s cars have sailed through the MOT with EGR blanked off. I’ve not seen, nor heard, of a single example of a vehicle failing because of a blanked off EGR.

Am I right in thinking that the EGR is closed when the engine is warm, and opens when the engine is cold or under load ?
if so then blanking it off wont affect emissions on a warm engine not under load as tested

The EGR is designed to reduce NOx emissions which are currently not tested. However, they do increase particulate emissions; so a diesel fitted with an EGR but not a DPF should have the EGR removed in the public interest. That's my story and i'm sticking to it.

I'd go with that.

Yes it will pass, just make sure you give it a really good thrashing before you get to the mot

How long do we think it will be before they start nox testing ont mot in UK?

Int theory there will be a known nox emission value for the vehicle when it was first built. So they could at some point int time start checking vehicles operate at that value, with a bit of tollerence.

Just wondering

Some time. NOX testing is done on a rolling road, over several equivalent miles and with hugely expensive test equipment. So NOX testing won't be part the annual MOT for some time yet.

MOT tester will give a fail if he can see evidence of tampering with emission systems,
However he is not allowed to remove any covers so he cannot see anything.

Both my brother (td4 03) and I (td4 56) have had our cars passed with deleted EGR valves within the last 6 months.
