Default Belt Tensioner / Fuel Pump

FYI - After 10,000 miles, my 2014 Coupe needed the belt tensioner and fuel pump replaced.

The mechanic told me there is a service bulletin out regarding the belt tensioner possibly leaking hydraulic fluid. After he had replaced the belt tensioner, he heard an unusual noise from the engine area (drivers side) as the car was idling. He diagnosed the noise as the fuel pump and replaced it. Not sure what type of noise it was, but the mechanic said after he replaced the fuel pump, the noise is now gone.

What was the symptom of the belt tensioner needing to be replaced? Did a code get tripped? Check engine light?

Besides finding drips of fluid under the tensioner (which I did), it starts out as this...

I had to replace the fuel pump on mine at about 12k miles.

my belt tensioner failure sounded like a rattle in the center of dash. Noise is when the engine switches from 4 to 8 and back. And the small puddle of oil under the engine front.

Honestly, I never noticed any symptoms myself. The mechanic noticed hydraulic fluid sweating around the belt tensioner. He probably caught the problem before it actually started to affect me.
