Hi all! I posted previously on this topic and someone was kind enough to direct me to XenonValot's remedy involving drilling the shunt. I printed that page and took it to a local repair facility that was willing to take on the job. The tech looked at the panel and told me that it didn't look anything like what was depicted on XenonValot's website. I emailed XV and they replied that they only provide tech support to their own customers, so sorry. Has anyone else performed this mod on a 2004 C70? If so could you point me to the correct place? Thanks!
