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.

POST 1 / ORIGINAL POSTEROriginal post

Hi Guys Just tried to put my 996TT through its first MOT and it failed ! 1. Exhaust Emissions. The CO is 0.61% Vol but needs to be less than 0.30%. The Exhaust is not a standard one, its was installed by PSI motorsport. Any suggestions ? 2.The car is a left hand drive and failed on the fact that the rear fog lamp is incorrectly mounted to the left side (should be rightside) Any suggestions ? Many thanks.

POST 2 / ORIGINAL POSTEROriginal post

Problem Solved ! I took it back to where I bought it from and they managed to pass it by making the exhaust very hot. They also rewired one of the reverse lights to make it a fog light. Job Done.
