Just bought a 51 plate C5 last Sunday & have a few issues with it, nothing major just like to get them sorted. Cigarette lighter doesn't work, don't want it for cigs but sat nav etc. the 12V socket behind handbrake works fine, do they share a fuse or different, if different where is the fuse please. Outside temperature sender the one in the N/S mirror appears to be sending duff information, it's not been 91 degrees going to work at 6:30 in morning. If it's not important I'll not worry about it. Offside rear door doesn't unlock when central locking opened from fob, using button on dash opens it & if you manually open door from inside it then opens. Lastly it has a 110bhp sticker inside of door, & the tax paid was £115 by the last owner. I've just had a discussion with my father who has a 90bhp Picasso & he reckons that it's 90 not a 110. He only pays £115 for his & reckons that a 110 is £145, I've checked the V5C & there's nothing on there that's conclusive. Alan...
