I have a 2005 Boxster S and I think I zapped my front control unit when I used microfiber cloths attempting to polish headlight. I get the 'Visit Workshop' message. After doing some reading on this forum, I think that's it. So picked up another one off ebay after unsuccessfully trying to clear the error code. Now how to install. I think its located in the frunk on the passenger side. But I cant move the carpet back enough to get to it cleanly. Any help would be appreciated. Also, once in I think I either need to take it into a shop to re-program the part or buy/rent a PIWIS unit to do it. First i need to get it off the car... Attached is a pic of where I think it is. (also sorry if this ends up posting twice. I think first time failed but not sure now)
