    after we all checked our shoes for dog-poo we came to the conclusion it was
    the air con. a Google search suggests an aerosol spray fix, if so the q is
    where do we aim the spray? and any tips or other ideas?

    Mold or bacterial growth in the evaporator is common. Where it is on the
    V70 I'm not sure, but it'll be down under the dash somewhere. In my 740
    I was able to remove the resistor for the blower motor speed control and
    spray disinfectant in there.

    well good news and the other sort!
    firstly Halfords have a can for £11.49 which you sit behind the passenger
    seat, put aircon on recycle for 5 mins and all is better, even has a pic on
    the box of a Volvo's dashboard!
    secondly today I saw a similar product in Lidls for £1.49 bugger!

    I used a can of oust ( http://www.oust.com/ ) , cost about 1.50 from
    tesco. As you say put the aircon on it's lowest temp and recycle, spray
    the oust into the car for about 30 seconds and close the door. You
    may need to do this a few times but it does the job. Also cleared the
    "doggy" smell from it's previous owner.

    Since the AC has mold growing inside you should also have a dealer
    check the car computer. Make sure that the firmware is set to have
    the AC fan come on about 1 hour after use to blow out the condensation.

    How long does the fan run for? I've considered building a little timer
    box to accomplish that on my 740, I've had to spray lysol into the
    evaporator every few years when it starts to reek like old milk.

  9. The fan waits about 10 minutes after you shut off the car and then it
    runs for about 5 minutes.

    For cars experiencing problems, Volvo has a two stage "cure". They
    spray an algicide first and if that doesn't solve the problem, they can
    clean out the affected area and treat it. On our 850 we have had this
    done a couple times. On the V70XC, the timer on the fan works perfectly.

    On my S80 and V70 it waits about 1 hour then runs for 5 minutes or
    so. A one hour wait makes sense because it will allow built-up frost
    to melt.
