Got my first bong this morning. I always find keeping the car in the garage helps keep the frost off.

I think my cold bong is broken!

3.5C and flashing warning on the LCD screen but no bong and no yellow snowflake. On the way to work it got to 4.5C then down to 3.5C - again no bong but flashing snowflake on the LCD screen.

To test my bong I undid my seatbelt and I got a bong also leaving the parking light on and opening the door I get a bong but no cold bong.

Out of warranty now.

Any ideas how to fix my cold bong?

Surely the cardboard ends up soggy within 1 or 2 uses though?

Not if you've somewhere you can pop it to dry out during the day. I also have access to a plentiful supply of cardboard which helps greatly

Last night it was the plastic sheet though and I'm glad I did as we had a frost.

Had my second bong this morning (first last week).... 2.5 degrees, the ice on my windscreen could have sunk the titanic! :(

(we are so cool! )

I got bonged for the first time last night too - 3.5 coming home from the pics.

And then bonged again this morning.

I'm feeling a little over-bonged already and it's only October! :S

More BONGs here as well.

Winter tyres going back on tomorrow!

That's the best way...works a treat for me too. Just need to kill the "there's something wrong with your car, sir" type bong now. Glad that's tomorrow as it's been driving me mad all week.
