Car appreciation... the aesthetics, the engineering, etc

Unblock all the drains for everything.
Take the carpets out and dry them
mop up all the water
hire or borrow a dehumidifier
Check your heater hoses aren't leaking.

Thanks, I'll break out the Haynes manual and have a look. I'm not good at car stuff. Computers, bikes etc are fine. Tons of steel that might kill me or other people, not so much...

this precise issue just killed my buddy's 2002 (ish) audi a6.

(sorry)

edit: i do have an humidifier you can borrow, if in east london

Oh no :( I may take you up on the dehumidifier (presumably that's what it is, the last thing I need is more humidity in there). I am indeed in east london.

Cheers!
