I'm looking for the same thing also.. i need to locate the speed sensor and related connection. Did you manage to get it? Thanks

Hi guys I had an issue with My L322 2008 VC FAN , it runs continuously... No fault codes.. however i have swapped it with other 2 cars in my friend's garage and same result.. On OBDII live data shows fan speed is 0 .. so I think that's why its running all the time.. Anyone knows where is that...
