'99 996 3.4 ULEZ NOx Emissions

[blackmamba]

Thanks to those that have contributed on this thread, I have received my CoC from Porsche for a 996.1 GT3 and TFL have confirmed it is ULEZ compliant due to the NOx reading. I wasn’t sure what to expect but the whole process was very straightforward and TFL surprisingly responsive.

Much appreciated.

Would you also need to get a separate exemption for any of the ULEZ outside of London?

YES

I have been through this. Feel free to ask any questions. There is TFL and then there is the rest which are all on one system. So 2 systems.

In Summary - copy pasting from another of my posts elsewhere -




The new Clean Air Zones all round the country use a different / separate list of vehicle types to the TFL site.

Just because some other helpful Porsche Nerd has jumped through the hoops to get their car [and therefore any similar car maybe???] marked as ULEZ exempt on TFL does not transfer over to the new Clear Air Zone system and therefore all the Clean Air Zones all round the country.

I bought 2 more Porsches last year and checked both were ULEZ exempt on TFL before I bought them - they were. Then I drove through Birmingham in one and got fined. That's how I know all of this. This was my 986 which I have now had reclassified as ULEZ exempt in all Clean Air Zones. Took many months.

Just been through this process again, but for the various Clean Air Zone's popping up around the UK. Thanks to the hard work put in by ATM to deal with the DVLA with his fleet of Porsche's, I had a rough idea of what to expect and they were surprisingly responsive.

Made a general CAZ enquiry with vehicle details, got the automated response asking for more details/evidence, then sent the below through with a copy of the V5 and the Porsche Certificate of Conformity:

Dear Sir/Madam,

Please see the attached document for a copy of my V5 and a copy of the certificate of conformity, including the covering letter from the manufacturer on headed paper, that states the emissions output of the vehicle. Please note that Porsche use the vehicle VIN number to identify a vehicle to issue these documents. The VIN matches across both the V5 and the Certificate of Conformity.

As I understand it, in order for a vehicle to meet the Euro 4 regulations it’s emissions must not exceed the following:

CO ------------------ 1.0g/km
HC ---------------- 0.10g/km
NOx ---------------- 0.08g/km

As you can see from the data supplied by Porsche, shown on page 5 of the attached PDF, my vehicle emits the following:

CO ------------------ 0.269g/km
HC ---------------- 0.079g/km
NOx ---------------- 0.055g/km

As I understand it, based on other individuals attempts to certify their vehicles as clean enough to drive within a CAZ, that in the absence of a confirmed Euro status, the Date of First Registration of a vehicle, and it’s emissions values recorded at registration, can be used to determine whether it likely meets the Euro 4 minimum emissions standard for Clean Air Zones.

Could you please confirm if this is enough information to certify my vehicle as being clean enough to be exempt from charge in the CAZ’s?

Many Thanks,
Mallone

They replied within three hours saying I was right, they will update their systems, and the vehicle is exempt from all the CAZ's. Pretty easy!

That's better than I did, well done.

I'm wandering now if someone so inclined could use the Certificate of Conformity from a vehicle which meets the regs but with a slightly altered chassis number from theirs which doesn't. Not sure how many laws this breaks but you understand the idea behind it right?

I'm in the market for a 996.2 and unfortunalty I live in the ULEZ zone. Putting in the numberplates of prospective cars it looks like the 2003 c2 is not compliant but the 2004 is? Do you think this is a TFL quirk or porsche released an engine update in 2004 that meant it went from euro 3 to 4?

Either way it looks like a porsche certificate of conformity does the job with TFL

I'm surprised by Mallone above managing to swing it with a 99 996 which is a gen 1. As far I know the gen 2 should be even cleaner still. Porsche generally make their cars cleaner every year. But thats just a guess. In any case if the 99 996 3.4 can get under then why would a 2003 not also?

I would try some more number plates. I just tried my friends [green] and his is not ULEZ and neither is mine.

[jwbc1984]

Its bonkers - thats a 03 996, if thats ok (although i did run it through the ulez and it couldnt find the car to check) - I was looking at this one ANOTHER 03 996, according to the checker: non compliant.

This one, a 04 plate, compliant!:

When I was looking for a P 996 or 997 last year I was told by P that all their cars from 99 onwards are ULEZ compliant and that the issue is with TFL.
I think it's something to do with the e-gas throttles being introduced.

Right but CAZ is totally different and possibly harder to swing - all guess work because I've not found anyone who knows the rules for certain. If it is EUR 4 for CAZ then this is different to TFL who just worry about NOx meeting EUR 4 and not all 3 metrics.

EUR 4 is

CO ------------------ 1.0g/km
HC ---------------- 0.10g/km
NOx ---------------- 0.08g/km

You can see the NOx above. Some pre EUR 4 cars meet the NOx but not the others.

No doubt Sadiq will revise rules again in due course!

Very interesting, I hadn't realised that TFL only cared abut NOx.

[Scrump]

My 51 plate 996.2 Carrera is both ULEZ and CAZ compliant according the relevant online checkers.

As I understand it yes. But only from reading various Internet chat. I started studying up when I got fined for driving through CAZ in Birmingham when my car was listed as ULEZ compliant. Now I know they are totally different.

My 52 plate 996.2 is TFL London ULEZ compliant. I know because I went into town on Friday and paid the congestion charge in the evening and the website said so.

I checked my 2004 997 C2 on the CAZ site and it fails Birmingham and Bristol. I don't visit these places but I've sent an email so we'll see what I get back.

[Dammit]

My car is a SA vehicle, originally, which means that Porsche UK refused to supply a certificate of conformity for it (despite it being a standard, early 996 in terms of cats and so on).

Anyone have a suggestion of a route I could follow to get something official that shows it's emission status?

[Smollet]

Useful post. Thanks

I found this site when I was researching a motorcycle, I didnt use it in the end but there must be something similar for cars?
