'99 996 3.4 ULEZ NOx Emissions

[Mallone]

Posted this on 911UK but only got a limited number of replies so thought I'd ask here too before contacting Porsche...

Having just had success with convincing TFL that my 2002 Honda Transalp falls below the ULEZ NOx limit, despite not actually being Euro 3 compliant, I'm looking into seeing if my 996 might escape the penalty too.

I requested a 'Certificate of Conformity' from Honda that showed the NOx emissions were below the Euro 3 level and after sending it off to TFL they have written back to confirm it's now exempt from the ULEZ charge. Result.

I know cars need to meet Euro 4 spec to avoid the ULEZ charge (which the facelift 996's already meet) but my early 1999 car doesn't meet it apparently. Cars that meet the Euro 4 spec need to produce less than 0.08g/km of NOx.

Question is, without me requesting a certificate of conformity for Porsche at a cost of around £100 (and finding out the hard way that it may not pass the test!), does anyone know what the early 996's actually produced in terms of NOx? Does anyone have a certificate of conformity for any of these early 3.4 cars?

What does it come up with when you put your reg in here, mine is a 2001 3.4 and is compliant, a mates 2000 3.4 also checks out ok

Yep. Checked already. Fails it.

But so did the Transalp, until I could prove it's NOx emissions otherwise....

Is your mates 2000 3.4 a cable throttle?

Mine is 2000 3.4 but fails....

Hi Mate,

Did you get anywhere with this? I'm in the same position - with a 3.4 996 which is listed as failing the ULEZ charge... and I live just inside the expansion area. Did you manage to get a certificate, and if so was it any use with TFL?

I did get somewhere. My 996 is now ULEZ compliant!

Result!
But isn't the Nox figure readout supplied with every MOT? Couldn't you just send that off, or will it fail that way as the car is old and the NOx figures are worse now than when new?

It doesn't work like that sadly.

Great stuff! Thanks for replying and for pointing me towards your other thread. I've put the wheels in motion... looks like I stand a decent chance here!

Wow! So glad I looked into this thread. I was about to sell my 2002 3.6l 996C2 because the TFL ULEZ vehicle checker said that my vehicle does not meet the ULEZ standard.

Unfortunately, there is no NOx info on my V5 but from what has been said it looks like there is a very good chance that my car would meet the ULEZ standard. Is this correct?

From the TFL website, it looks like I will need the following to prove that my car meets the ULEZ standard.

"Documents you need for proof
All vehicles:
A copy of the vehicle's V5C or non-UK equivalent
Plus
To prove your vehicle meets the ULEZ standards:
A letter from the vehicle manufacturer's homologation department stating the vehicle's Euro standard or a conformity certificate"

Is this correct?

I googled "porsche conformity certificate pdf" and the first result gives a form that suggests I can request a Conformity certificate from Porsche for my car for £106. Is this correct?

Thanks for potentially saving me from selling my 996!

[shalmaneser]

Just email porsche they send the cert for free.

[996c2]

Just in case there are 996 owners out there who are not aware that their 996 maybe ULEZ compliant despite being manufactured before 2004, I was able to get TFL to confirm that my 2002 996C2 is ULEZ compliant by sending the the certificate of conformity.

Porsche sent me the certificate of conformity for free after I emailed them at "[e-mail]" to request it.

Just had a confirmation letter via email to confirm my 1999 996 c2 Cab is compliant. No ULEZ charge! Got the certificate of compliance from Porsche (free) and supplied the accompanying letter plus V5 to TFL and hey presto. I could do easily sold the car or spent a few thousand kpgrading for absolutely. I reason. I live right on the edge of the new zone so it would have been a real pain.

Yep glad this thread has helped others out!

I got a letter from TFL saying my Mk1 996 GT3 was not ULEZ compliant.

Is it likely that all Mk1 996 cars have been grouped together and that I may be able to cross the North Circular without a fine?

it is handled by number plate recognition so have you used the ULEZ reg site to see what that says?

Ah nightmare I tell you what I'll do you a favour you can have my C2 3.4 I'll have your GT3. I've just fitted new rads though so maybe some money my way too? Do let me know, I take payment in half eaten mars bars and bits of string.

Wait - I will ask for my GT3 Mk1 CS Certificate of Conformity from Porsche and will attack the morons at TFL with it. Hopefully the CoC will show an acceptable NOx figure. Won’t tell them about that 100 Cell cats and MM Exhaust installed by Manthey

[Biggy Stardust]

I've applied for a certificate for mine, thanks very much for the advice.

Ladies, Gentlemen, gimps, dwarfs and any and all others inclusive or not.

I've been researching this hard in the last couple of days because I've been handed a fine from the Birmingham Clean Air Zone for driving my pollution pumping turd in their lovely urban area full of flowers, butterflies and tree hugging hippies.

I believe the new Birmingham Clean Air Zone or CAZ use a new website of data. It seems that the TFL for London and this new website (below) have different data. TFL for London say my car is exempt already even though they also say it is EUR 3. The new website just says not exempt and pay up you climate killing monster you.

https://vehiclecheck.drive-clean-air-zone.service....

So not being the type to lie down and take this on the chin I have pushed back. My digging has come up with the following.

The new website is managed by the DVLA. They acknowledge their data is different to TFL or London ULEZ. London TFL is happy with just NOx numbers but I believe DVLA and Birmingham CAZ are stipulating EUR 4 ( for petrol cars ) which hopefully means CO, THC and NOx. I've been pointed to this very helpful website by another super helpful PHer called NomduJour - thanks.

http://www.emissionsfinder.com/porsche-all-models-...

CO Emissions
613 mg/km
THC Emissions
88 mg/km
NOx Emissions
48 mg/km

This gives the results for my Boxster - shown above - but hopefully you can navigate to other models. Now it shows that my Hair Dresser's car does meet the EUR 4 standards but the DVLA won't accept this. They require the Certificate of Conformity. So I have emailed Porsche to ask for this and I'm awaiting their reply. In case anyone is interested you can find the EUR 4 standards here along with all the others -

https://en.wikipedia.org/wiki/European_emission_st...

I also have a 1998 996 C2 3.4 manual coupe cable throttle. The website mentioned above which shows vehicle emissions numbers does not list this model - or I couldn't find it. So I'm still in the dark about this one.

I also have a 2001 996 C2 3.4 manual coupe e-Throttle which I think the website shows the following data for ... below ... which are within the EUR 4 petrol limits and therefore all good. Let's not mention the remap, larger throttle body and fruity exhaust.

CO Emissions
269 mg/km
THC Emissions
79 mg/km
NOx Emissions
55 mg/km

I hope the numbers from this website are good and Porsche confirm. Then I hope these zones dont all decide to change to EUR 5 and then EUR 6 or eventually we'll be priced out of the market.
