Hearing a squealing or grinding noise from your engine? Might be time to replace the idler pulley. This X AUTOHAUX pulley is a direct fit for a bunch of Audi and Porsche models, including the Audi A4 (2.0L 2016), A6 (3.0L 2009-2018), A7, A8, Q5, Q7, S4, S5, SQ5, and Porsche Cayenne (2011-2019) and Panamera (2012-2016).
It's made from metal with an M10x1.5 thread size, about 3.1x8cm overall. The pulley helps guide the accessory drive belt, keeping tension right and preventing slipping or misalignment. Just make sure to confirm your exact vehicle model and engine before ordering – especially for the A4, where it fits models with a short water pump.
This is a non-OEM part, but it's built to meet or exceed original specs. A must-have for DIY mechanics or anyone looking to save on repair costs. Keep your engine running smoothly and quietly!
