Sniff Test
Hello,
Sorry if this a bit of a stupid question but I am looking for some advice.
I have just purchased one of the ebay sniff tests to do on my D5 XC70 and I am wondering when you use it? Can the car be cold or does it need to be warm, if its got to be warm do I warm it without the coolant cap on or whilst its been for a drive?
I don't want to do it wrong or burn myself in the process haha
Cheers Greg
