The two parts aren't the only ones. There are a couple more items, but the list is shorter. Idler pulley, tensioner, bolts, etc. The dealer is obligated to adhere to Mercedes regulations. This comes with no spare parts. Plus, labour is expensive. The Belgians. thrice as much as a standalone garage. That area is called Wallon. Every single garage in the area has completely lost my trust. Due to mental exhaustion, the only decent one closed. However, compared to high-quality aftermarket components, the pulley is actually more affordable. They stand firm on the two-year warranty, which is the only perk in my book. Including the subframe, they have dutifully honoured everything. It isn't accurate to say that the pulley is loose. Here we have a pulley/harmonic damper. The structure is disintegrating. It's not easy. In French, I understand everything. Aircraft jargon is my speciality, but automotive lingo is completely foreign to me.
