I have same issue, I made mistake to order the part from China. I am working on replacing it and my thermostat water pump oil filter housing and oil separator. I am looking forward to some instructions pictures from you.
__....has a hole in it, the heat from the engine seemed to make the plastic brittle...
This has happened to me as well. I am currently seeking a lawyer for a class action on this. If anyone is interested in joining it, let me know here.__
Did you happen to take a picture that you can upload?
I'm thinking that this is a widespread defect, which can cause harm and therefore should be officially reported.
Hopefully you’ve gotten it fixed since then.this has definately happened to my 2018 X117 CLA250 - tabs crumbled when ran my fingers over it, need a to get it replaced soon before the hole gets bigger
Temperature is about normal. Mercedes tend to run a little higher in temp than other cars.I just discovered mine has the same issue. Bought used. Tried to do a transmission drain and fill new filter etc. I’m a mechanic this was a clean car old guy owned it. As soon as I went to move the air box the entire carpet air intake crumbled. Currently being held together with duct take. Till I can go to the dealer for a replacement tomorrow. Anyone know what there temp normally runs at too? I’m a ford tech never had German cars before. I’m running a bit over 80 rn on a 2014 Mercedes cla 250 front drive. Thanks in advance!
I have about 5000km with the AEM cold air, seems to be doing alright so far. It seems to be a thicker, more durable plastic than the stock plastic. My only complaint is that the fitment isn't quite perfect so it doesn't sit right in my car. That, and the fact that it's not as easily serviceable as the stock airboxFor anyone with an aftermarket replacement like the K&N has that held up well to the heat?
a p0299 might be the hose that runs from the front of the motor to the rear. Pretty expensive part. Its the pcv system and Mercedes normally recommends replacing the entire hose. You might inspect the hose thoroughly to see if you can see any visible cracks but mine was very very small and you would never see it without pulling the entire system out.Resurrecting an old thread here. I have the same issue and at the same time I noticed it, I got a P0299 underboost code. Does anybody know if it might be related? Intake pressure off or something because extra hot air coming in through the hole?
