ULEZ (Ultra low Emission zone) Euro 4 Compliance

[Julian Carlson]

I guess I am clutching at straws here, but I am interested to know whether any 911 Carrera 3.2 owners in the Greater London area have a modified their exhaust system to achieve Euro 4 compliance? I would be ineterested to know how? I am just outside the zone and can avoid travelling through it, but I feel that its only a matter of time before I am impacted by it somehow.
Any thoughts on this lost cause would help.

I think the odds are virtually non-existent. To the best of my knowledge ROW 3.2s aren’t even Euro 1. I think Euro 1 requires a cat; higher levels require much more in the the way of emissions management and control (better filtering of vapour emissions from the engine and the fuel system, lambda sensors, quick warm-up cats, cleaner cold start, etc, etc). It’s far more than just the exhaust and on top of all the changes you would need someone to certify it and then convince the DVLA or whoever makes the call to accept the certification.

And I think it wasn’t until some way into production of the 996 that 911s become Euro 4 compliant?

My advice - forget about it. Lobby for classics to be exempt - odds of success are better.

You're correct, I have a 2004 996 that isn't subject to ULEZ.

There is a rolling 40 year exemption for all classic cars, so anything pre 1981 is exempt. Still 2-3 years before the earliest 3.2's start to become exempt though.

I'm not aware of anyone who has modified a car to meet later Euro emissions standards. On the face of it, all you need do is to fit a Cat and meet the correct emissions levels... how you would then get that approved I have no idea.

That makes it sound simple. It wouldn’t be. A 3.2 ECU has no provision for lambda feedback. And the 3.2‘s Motronic and injectors are quite crude when compared to a car that meets Euro 4 - they simply aren’t capable of the fine metering/calibration/monitoring required.

Thanks for the responses, it makes perfect sense with reference to the ECU. I will take the forums advice a forget about it and just adjust my route should it be necessary. My 3.2 is a 1988 model, so I have about 7 yrs to wait to be exempt!! I will keep an eye on the countdown clock.
Thanks again for responding !

Interesting but depressing information.

So I'm clear then; driving to the Le Mans 24 Hr this year means that me and my (standard) 964 will be 100% non-compliant (in any Crit-Air bracket) in the new expanded zone around Rouen?

I have a 89 3.2 and literally live 200 metres from where it will start in Barnet.
My only hope is for a change in the age of when a car is considered a classic car.
I have signed several petitions , but the reality is this is just a revenue generating scheme, so don’t have much hope of a change.

We had the same issue last year for the classic with a couple of our cars in the group.

We actually ended up going around the side added about 15 minutes and meant that we didn't sit in crappy traffic.

Good to know, thanks. The only other alternative I have used in the past when the Rouen tunnel road was closed was to skip round the top but then come down to the southwest of the city and cross the Siene at La Bouille on the ferry. I will nearer the time look again at the zone boundaries and plan the route round. That, or I just give it go through Roeun (like hundreds of locals do) and ignore it.

IMO the chances of getting pulled over in any of the Crit air zones are low as it seems to be a case of being pull over rather than a camera system like ULEZ. Although this is going to change in 2024 when the introduce cameras.

The French Classic automobile association have successfully lobbied for an exemption for classic cars (not sure what the criteria are ) or how it’s being applied though ?

Interesting. Does seem then it's a case of taking a chance on being pulled over in person or not. If the situation changes (ahead of mid-June), or any updates of note, do post up please.
