I had (have) an issue with mirror heaters. On my previous Leon's (MK3.5 and MK4) the mirror heaters worked whenever the switch would be in the heat position. Late summer when mirrors were 'misted over' in the morning start up but temp may be 12 degrees or so the heaters didn't work. Booked it in to the
dealer to check while I went for a walk. When I returned told me all good and they only work below a certain temperature and showed me a handbook extract. Strange (BS?) the last 2 car handbooks detail the exact same text and heaters worked independent of outside temperature. FF to November and the car is frozen up, mirror heaters don't work...and its very cold! Tried with/without HRW on/off even changed drive profile when it worked but couldn't understand why this would affect it. Thought about ringing
dealer again to book in then later in the day they worked. Couldn't understand why and it hasn't been freezing cold (yet) since then. I'm loathe if it works some of the time in the winter to let the
dealer attempt to find an intermittent
problem like this when I'm sure it'll be fine when they test it and I don't fancy them stripping the car out to try and find a 'dodgy' connection somewhere. Now where's that scraper
