Sizzling noise after switch -off

I've noticed that on a hot day, with A/C on, once i switch the car off - a sizzling noise can be heard coming from the front passenger side.



I've researched and understand that others experience similar things and that it is nothing to worry about (just condensation dripping onto exhaust), but i want to know if anything can be done to eliminate this?



I previously owned an e92 in South Africa - very similar hot conditions and always used the A/C, but never ever heard such sizzling noise after switch-off...
