Hi all, can I please seek your advice on whether the small crack in the centre is a major issue? I am looking at some 2017 C43 AMGs around Perth, Australia and more than a few of them have this part cracked.

Thank you!
That is very easy to crack, when my 2017 was still in warranty my dealership cracked mine, restricting airflow and cooling to the ecu, I would recommend replacing it.
It is very easy to fix with a soldering Iron if you have any.
just melt the edges together and smoothen out with the tip.
very common place to have a crack.

Thanks W205C43PFL, how much did the dealership quote you for it? Any idea of the costs involved?

Thank you MJPfin! Any idea on the name of this part so I can search it up and maybe see some videos of others fixing it?

Actually, you made me curious : ) how about did you solder it, like just heated both sides of the plastic or you added some kind of material?
First you need to test the plastic on what temperature it melts. Too hot and it just burns.
at melting temp you stitch the seam plunging the soldering iron tip across the seam and up and move couple of millimeters and stick it again. Just like stitching it together.
Slightly pushing the material in to the previous weld.
this way you melt the seam together to a good bond.
After it's done you can use a flatter tip to smoothen out the seam.
Lots of videos and tutorials in YT if you never fixed plastic parts. Works on all thermoplastics.

The crack is of no significance and does not affect function in any way, but rather is only a cosmetic annoyance.
Does it not channel air to the heatstink and ECU? I understand newer MB engines doesn't have a channel in the middle for example the M256, I understand it is not necessary but isn't it good to have?
I plan to push the engine hard often to enjoy what sport mode has to offer, perhaps I will just pay some money to get it fixed... Unless it doesnt even direct air to the ECU and is a cosmetic air channel?
I was quoted 310 USD by a local mercedes specialist to get it done. Seems like a fair price...

It does (kind of?) if you lift the engine cover and look at the underside, you will notice. That said, does it really make a difference? not really.
Every 10deg C of heat you remove from electronics doubles the lifespan of the components. And the ECU is sitting on top of 80deg C engine.
I would not disregard the cooling affects of that duct so easily. Mercedes engineers are not stupid and make things just for the fun of it.
It does serve a purpose, otherwise it wouldn't be there.

Really, what is up with that ? The ECU sitting atop the engine ? OK, in the past, ECU have been put in stupid places like the floor, but most cars put the on the firewall somewhere. Why would you place the ECU atop the engine, other than assembly ease ?

I mean, I agree with having better cooling is better for electronic components, I don't know what to say with MB's decision to put it on top of the engine, it does have a heatsink integrated but more cooling is always better.
Does anyone know what that entire intake piece called, basically OP's image with the red arrow pointing but the entire piece? Does anyone have a part number by chance? Thanks! not talking about the engine cover.

It is a snap on (and held in place with push tabs that looks like screws but they are plastic) so that is the part number, if you want to replace it you can buy it based on that part number it is around 200 USD before labour and tax, not sure about Australia.
+1 Mine was broken when I bought the car. I thought about putting in some vertical support at the break. Ideas?
I am considering welding it as suggested, don't bother with RTV silicone which I did, you can put that there, let it dry, if the vehicle is never going to be driven ever again, it won't collapse but as soon as you drive it, it will collapse again, that is why it is either weld it or replace it altogether.
