Hello! Since Tuesday I bought my Fritz – as I call him 🙂 from the PZ. Yesterday I started a round and arrived at home I wanted to program the home link times. So cover up, ignition on and off it goes. 10 minutes later I was finished and the car at the start only a heckish “click click click” The Approved Angel said that the battery was loaded, but completely empty. I would not have expected that now after a 2 month old 111 points check! r anyone experience with the lifespan of batteries in a 997 convertible?
