Drivers side windscreen misted up

[Chrisem]

Hi everyone have got an annoying fault with my A6 avant,the drivers side of windscreen is constantly misted up,unless I have one or two windows down on a warm day. Especially at night time it's a pain having to wipe it clear all the time,once misted up it seems almost impossible to clear with all the heaters/demisters set to max, but the passengers side is completely clear. The rest of the heater system seems to work fine. I also recently changed the cabin filters as they were pretty bad,but this hasn't made any difference to the fault.has anyone else had this problem,or got any idea what might be causing it? Would appreciate any help,thanks

Is the windscreen the original or has it been changed? If it's an Audi one it'll have an Audi part number.

Hi thanks for your reply,as far as I can tell its the original screen,still has the original audi stickers on etc,though this one is not a heated screen with the elements in it,been out in the car tonight and it's getting really bad,actually makes it worse if I use the air con and demister settings to try and clear it,could this possibly be that it needs regarding?? It's not been done in the last 2 years I've had the car

"Regassing"

Yea it's worth looking at getting it regassed. It should be done ever 2 years. 

Does sound like it's the original screen. 

It makes me wonder if moisture is getting into the car - ie a leak somewhere. Are the carpets dry and spare wheel well free of water?

Everything seems dry,dont seem to have any water getting in that I can tell,think im going to get it booked in to be regassed as the warm air also stinks at times so guessing it needs flushing through and recharged. I've also heard their are drain channels on these cars that block up and can allow moisture to get in,but im not sure where these are on the car

Sounds like a plan, I know on older Audi's like mine the AC can leak due to blocked pipes under the passenger seat.

Hi,

Is it just the drivers side?

Had something similar many many years ago, when it was just one small section of the windscreen that wasn't demisting properly.  I put the fan on full blast, and aiming towards the windscreen, closed off all the other vents.  I heard something rattling.  Semi stripped the dash area and found loads of sweet wrappers blocking the outlet.  AHHHH, the missus.

Just a thought.

Lol unfortunately think mines being causes by more than sweet wrappers,it started off with just the drivers side misting up no matter what setting the heaters were on

Last night was out in the car in wet weather and the whole screen is completely fogged up,if I turn on the heaters onto demist it actually makes it worse instead of clearing it haha. Also strangely if I have the air con set to cold on a hot day sometimes one of the vents will blow warm while the others are cold,very strange. Spoken to an air con specialist he says they are all signs that the system needs flushing and regassing,hopefully that might sort it

Same as mine, if old Audi's are looked after then they're reliable. Not cheap though but they're a labour of love.
