SEN0518 LED not turning on

I acquired 2xSEN0203 and 2xSEN0518 for an heart rate and oximetry application i'm working on. 

While the SEN0203 works perfectly fine, im facing some issues with SEN0518. 

The LED of the SEN0518 does not turn on meaning that i cant capture any signal using its I2C interface. The technical documentation says it can be supplied with 3.3V or 5V, and im doing the latest. I double checked my supply voltage using an oscilloscope and also by using it as supply SEN0203 which turned out to work fine. 

Has anyone faced a similar issue?
