Nasty smell in Prado

Gday
And water from under the mats...

Same here. Every time we stopped we looked at each other wondering who made the smell. Stopped the car and opened the bonnet and it was obvious where the smell came from.

I had that after the local ARB wired up the dual battery system wrong. When the wiring was corrected the second battery collapsed as it'd had no charge for over a year and the stink was not nice.
Some years back the Cook and I were on Home Valley Station and the manager was hunting for the cause of the awful pong in his Troopy.
I lent him a screwdriver and he took off various aircon vents and found a dead mouse. For something so small they give out an awful lot of stink! :-)

While I wouldn't discount a little furry critter, would have to agree with Doug that it may be a gecko or frog. It's amazing the amount of odour they give off when they are "ripe". We've had to evacuate our bedroom for a few nights when a gecko "suicided" in the aircon.

Would do a sniff test, to see if you can isolate where the smell is strongest, and maybe work from there. A bright torch can often make them easier to see if under the dash or seats.

"Nilodor" is a smell-stopper (available in supermarkets)that works well, though I reckon it smells a bit clinical. Have seen an undertaker use it before he zipped up a body bag some years back. I prefer Supercheap "New Car" deodorant to mask any in-car smells, odours or emissions.

Small birds can get caught around the grill area too and provide a lot of odour for a few days. Hope you find it or it dries up quickly
