GL 350 BT 2013
GL350 2013. Power loss, but no codes
My 2013 GL350BT suddenly feels slightly slower during acceleration.
I`ve not noticed anything other different with the car. (No rattling, encreased smoke from exhaust....)
Could not find any air leakage from the hoses connected to turbo.. (I`ve replaced the gaskets to the turbo inlet and PCV valve.)
So, what could cause my car to redused performance, but not to go into limp mode, or make any fault codes?
Could it be an O2 sensor fault..? Defect spark plug? Any other ideas?
Much appreciated for any help!

Make sure your gas (fuel) cap is tight, as a first step in troubleshooting.
Good luck.

The diesel has no spark plugs.
Agree with taking it in for the emissions class action warranty repair. It will get sorted out during the repair.
