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.

Hi I got cayman s and the car had been sitting in the show room for a few weeks. Its battery wasn't fully charged so the PCM wouldn't turn on. I got a new battery everything was fine took it for a short drive got it washed and parked it up. I could hear a clicking sound coming coming from near the PCM unit after I turned the car off. I woke up the next Morning and the new battery was dead. I can open the trunk etc and the lights come on but it won't turn over ???? Any ideas ?? Here's the car in Question if you guys wanna see her Beauty when I can drive her

It sounds like you have a short that is drawing current, or maybe an accessory is remaining on (radio, nav, fan, lights, ??). Can you take the car back to the place you purchased from and ask them what's going on? Either this is a brand new problem, or they knew about the problem ahead of time. Have the car's electronics been modified in any way? Maybe someone added a radar jammer, aftermarket stereo, etc?
