Since the temps here in the Plains States have really dipped down, I have had a chance to try the heated seats and found something interesting about them.....
DO NOT FART! LMAO

 

....self fogging or crop dusting is not recommended unless the windows are down or at least cracked.

 

Heated seats are the best, I suffer from back problems so generally won't buy a car unless it has seat heaters. One thing you can do to your X308 seat heaters is this simple little mod, which will have the potential to ignite those farts!! :icon_flamethrow

It's also not advisible to "let rip" if the air is on recirculate either!!

 

Hahaaaa....yes, it would quite 'magnify' the situation ;o)=)

 

My seats are just barely warm too so I bought these replacement thermostats in the 30C/104F specification.
5pcs KSD301 Thermostat Normally Closed NC Temperature Thermal Control Switch

Five for $4 shipped! That is enough to do all the seats and if they are bit hot or cold, I can re-order a different temp cut off spec.
