How to Replace the Belt Tensioner & Serpentine Belt on a EA888 Gen3 engine

[nd-photo.nl]

Follow this guide if you need to replace (or check) the belt tensioner (and serpentine belt), on your EA888 Gen3 2.0 TFSI/TSI engine.

The INA tensioner broke partially when I released the tension form the belt. Therefore I would recommend another brand, like the SKF unit I bought later.
