Hi guys
Anyone here has the Service Overview of the GLE?

I have Service Codes 2,3,4, and 15 with the Service B1 code. Due for 2 Years and 30,000km service.

I have an idea of what they are, just wondering if anyone have the specific sheet for W166.

From one of the description I saw, it said Inspect and Replace Poly V Belt. (Service 4) Isn't it too early to replace the belt?

and how much AdBlue will it take? I assume it was filled to top 15,000km ago, and how much Brake fluid (Mercedes specific? Dot #) does it need to be flushed?

Thanks!
