Hi everyone. A friend has a VW Polo twist 2004 which drains the battery every two days or so when the vehicle is standing idle. So she has been told by the VW garage the problem is the car radio - called an 'Alpine'. What the problem is they dont say but they do know they want £50+/hour to sort it out! How can I check this out? I'm a competent mechanic with a background in electronic engineering. So it should be easy but I would really appreciate some guidence on where to start or some ideas on where the problem is most likely to be. I just dont want to start pulling the facia apart and possibly create more problems. Many thanks and a happy new year to all.
