''99 C4 ULEZ Compliance

Hi all, I'm looking at an early C4 which I assumed would not be ULEZ compliant (a bit of a deal breaker for me as I'm on the cusp of the zone) but when I enter the reg apparently it is. I'm a bit dubious - can anybody else confirm? Reg: T264 EGD Thanks! Jon

ULEZ needs Euro 4. 996 was Euro 3 from M96.03 with SAI and electronic throttle. To get Euro4 you will need a 997. MC

As far as I'm aware all 3.6 996.2's are ULEZ exempt. this may help: http://911uk.com/viewtopic.php?t=137704&sid=8ecce7bb938374530c7c92723464e0c0

It seems like a real mess TBH. MC

Thanks for the info, that is what I assume - 996.2/997.1 onwards. So is this an anomaly? (See screenshot) It will be a massive pain if I buy a non ULEZ compliant car so I want to be sure.

I just checked and apparently my car - a 996 turbo - is exempt. Phew. Otherwise we would be moving house

If that is the system which decides the charges, that is all that matters isn't it? MC

Agreed, I just wanted to check as it seems too good to be true!

I've just entered my car (2000 3.4 C4) and it says: ULEZ charge applies to this vehicle Daily charge: £12.50 Why: This could be because the vehicle's details as registered with us show it doesn't meet the required ULEZ standards OR it's registered outside the UK and we don't hold any details for it. Must be an error on the system with your vehicle.

There is a possibility the published figures for the 3.4 are incorrect. I've emailed Porsche about this - watch this space. Have a read of this thread: https://www.pistonheads.com/gassing/topic.asp?h=0&f=&t=1668289&d=14818.76292 Specifically this post: shalmaneser said: Just a quick update - got my bit of paper from Porsche over the weekend. NOx is 0.187 as per the above, not unexpected but still a shame. Had a bit of a play around with the ULEZ checker and found a few more cars that seemed to pass even though they should be cable throttle cars. Oh well, guess I'll be in the market for a 997 this time next year, although an Alfa junior is tempting me at the moment! Alright so why is mine so low then? I had a few emails with another member here and it looked like the figures on his CoC were messed up - the 187 for NOx was actually the HC + NOx value. If you add up your HC and my NOx value (0.035g/km) I bet they come to 187? My HC value is 0.152g/km

Hi My 2003 986 Boxster showed on the checker as being compliant, then changed to being non compliant after the numberplate was changed. If you look at your V5 does it list all of the emission figures? The important one is the NO3 I think. If its missing from the V5 (and on the computer system) then you are automatically non compliant if the car is pre 2005 I think it is. So for me I have to get a certificate of conformity from Porsche and then get the V5 amended. And then get TFL to accept it. It has been done before, although not always with success. The early 986 Boxsters are non compliant, but they only have 2 o2 sensors and not the 4 of the later cars. maybe that makes a difference? My 993 is non compliant and never will be from what I can tell. All the best Berni

The 4 O2 sensors were introduced for Euro 3. ULEZ requires Euro 4 AFAIK, so having 4 O2 sensors is not an indication of compliance. MC

Just put my details on TFL, no charges show, think the cop outclause is " may be subject to change without notification, always check"

Mine has two o2 sensors and is Euro 3. However the ULEZ only cares about NOx emissions, which need to be under 0.08g/km which is the Euro 4 limit. The confusion come here: This is my certificate of conformity, requested directly from Porsche. Note that NOx is 0.187g/km. So I don't pass? But the Euro 3 limit for NOx is 0.15g/km? But my car is euro 3 (see III 96/96 above the emissions numbers) Then note that HC is 0.152g/km. But HC + NOx is 0.139g/km?! How is 0.187 + 0.152 = 0.139? Something ain't right.

What MY is your car? I was under the impression that Euro 3 started with the SAI injection and 4 O2 sensors with the M96/03 engine. MC
