I tried looking for it a year back, It is above the transmission oil pan. & its an absolute bugger to get to I'd say its nearly impossible without a ramp. Maybe easier to trace the pipe from inside the car will be interior strip down.

Recently experienced a smelly air con first 2-3 seconds at start up. I left mine on always to fresh air rather than recirculate smell seems to have disappeared. 

Remove cabin filter air con on spray Dettol disinfectant spray into the vents under the wiper blast 2-3 shots in 10 second intervals let it run 5-10 mins windows down & fit new cabin filter.

No smell now think it needs doing annually.

Similar setup to the IS350

Thanks for the advice, what i will do is that i will disinfect the whole system and leave it on auto mode after. I hope i will find the drain pipe today. I'll update this topic with pics of the location if found.

Any update, did you find location of the drain pipe?
