5WK4 7594 

ECU with integrated receiver 315 MHz 

5WK4 7593 

ECU with integrated receiver 433.92 MHz  

5WK4 7595 

LF antenna 

 
The two ECU variants use the same schematic, layout and assembly! The 
only difference is the integrated RF receiver (which is not subject to this 
homologation). 

 

Worst case calculation: 
4 drive cycles in 24 hours 
30 minutes to localise the vehicle
