2020 GLC300 4Matic How many air filters?
Hello, I'm receiving conflicting information from my dealer. After conducting research, I've discovered there are two primary air filters to consider:
1. The engine air filter, situated in the engine bay.
2. The cabin air filter, typically positioned either behind the glove compartment or in the left rearmost corner of the engine bay.
However, the dealer insists there are three filters in total. This pertains to the US California GLC300 4Matic model, equipped with a 4-cylinder turbo engine.
What's the forum say? Thank you.

Expand your research tools with YouTube. Search "GLC300 cabin filters". Don't stop looking until you see videos where they are going under the glove box.

3 is correct - I've changed them twice now on my 2020 - the one above the battery is easy but the one under the glove box is tricky and difficult to access and the engine air filter is also not straight forward - compared to my RX anyway(takes 30 seconds to change)

I have found that when changing the engine air filter, the disconnecting vacuum hoses is challenging. Using a hose grip plier made it immensely easier. I also used a long (t-handle preferred) Torx tool to loosen the 5 screws securing the filter housing. FOLDUP set and individual L-style won't reach 2 or 3 of them.

I do follow the WIS and it's an very easy process.

^That must be for a different model year than we have. I remember on my 2018 GLC it was on passenger side but On my 2020 GLC300 the engine air filter is on the driver side and is a nightmare to change. I'd love to have the tech guide for my car. If you have it, can you post it? Thanks

Didn't work for me - entered VIN 3 times and got error message - double checked each time - thanks anyway - maybe there is a way to find the instructions for the 264 engine without the VIN?

OK, not called vacuum lines but rather purge lines must be disconnected. I stand by my recommendations. I've done this air filter change about 5 times. This step is the only one that can pose difficulty.
