Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Good afternoon to all, In a effort to understand the published figures for the previous generation of 911, I would welcome all and everyone to post or email direct a copy of ,or just list the four emissions g/km figures as printed on your CoC and to which specific model it applies .I.E 1999 996 c2 3.4 coupe automatic. An engine code, type would be useful in addition if you know the type ,such as M96/03 etc. I would like to be able to compare manual to auto and turbo to 3.4 and 3.6 etc., to understand how the body type and transmission affect the figures if at all? If I could end up with a handful of each specific model variant that would be enough to establish a pattern if it exists. Anyone that does not have a CoC is entitled to apply for one free to Porsche cars Great Britain and I am willing to help with the form to fill out and sending it off , if that would help. This is on behalf of the club membership. All information will be kept in strict confidence, Vin numbers ,registration etc. will not be published. Christian sanger 993 register assistant.

POST 2Original post

Hello Christian - have you a link or email that we can use to get the CoC form please? Thanks, Graham.

POST 3Original post

Christian - from some posts on other forums around this ( or more specifically how it affect the ULEZ charge ) it seems SOME cars ( and at least 1 996 I have read of) have the NOX value on the V5 - in that case the owner was able to email a copy to TfL and have the record updated regarding ULEZ. I realise this isn't specifically what you asked for but you might get more data if people have it already without needing to get the CoC.

POST 4Original post

I checked my car on Tfl and it IS compliant. Its a 2003 996 C4. I also checked my V5 after reading Paul's post above and it has the following info: V.1: CO (g/km or g/KWh) 0.394 V.2: HC (g/km or g/KWh) 0.096 V.3: NOx (g/km or g/KWh) 0.021 V.4: HC+NOx (g/km) 0.090

POST 5Original post
