Check Engine Code P052E
I got the dreaded p052e code. I waited 6 months to have it fixed. got it done 3 weeks ago for FREE! I went to a trusted shop of ex mercedes mechanics. they said to call mercedes as now this is a known problem and mercedes is calling it an "EXTENDED WARRANTY" I went to mercedes and they said yes we will fix it for free and give a loaner out until it is complete. mercedes told me that because so many people are having this problem on models from 2015-2019 around 90k-130k, they are trying to avoid an action lawsuit so they will fix it for free. i hope this helps!
also, I just got in the mail another one that says they will fix your intake line assembly, and/or the partial load ventilation valve for 2015-2020 C/E/GLC/SLC AND SLK Models for free as well. this one is an extended warranty up to 140k miles.
good luck, and hopefully you guys read this. let me know
Thank you!

The dealership here in Manitoba Canada wants $2300.
Called MB Canada asking if they have a plan to fix that factory flaw as MB US did to their customers.
Very numb folks at MBenz Canada.
Benz - Never again.
MB is covering the issue now in Canada. Just take it to any local MB dealership

The Best of Mercedes & AMG
I have been following this thread and it has been amazingly informative so thank you to everyone who has taken the time to contribute. We just bought a used 2014 b250 with 157000km's on it and have just had the blasted light go on with this code. I read that some of you in MB and BC have been lucky enough to get MB Canada to pay for the fix. However MB doesnt seem to include the cars from 2014. Has anyone from ON with a car from this year had any luck with MB covering the cost? Any advice would be helpful - thanks in advance.
This has now caused problems with my DMV/Registration (you can't pass smog with a check engine light on) and I would like to sell my car and get a Tesla.
Has anyone else had this issue of the parts being back ordered with no ETA? I'm almost tempted to try another dealership in another state on the West Coast (if anyone else has had luck)? I'm SOO frustrated!!

I'm also in the same situation and the dealership told me ETA is probably a month. Now I'm thinking perhaps that's not true...
I recently had a check engine light warning light up. My 2018 C300 4matic has roughly 23,000 kms. I unscrewed and tightened the gas cap as I read it might be an issue and drove a few kms.
The check engine light did not light up or cleared after a day of driving. Maybe around 80kms total. I’m just observing it now as it is the 2nd day that it has been cleared.
I did scan my car using a OBD2 scanner that I borrowed today, It showed code P052E71 and P052E as stored.
I’m unsure if the code I read was due to the engine light warning a few days ago, or if it was an old code that wasn't cleared ( Bought the vehicle 4 years ago as a Certified Pre-Owned )
Not sure if Canada now covers this. I saw the letter above the thread, I believe I got something like that but unsure if this is what it is for.
Given the code just cleared automatically after driving, do I just observe for now?
Or should I contact already the dealership and mention this, and also show the letter?
Did you get yours diagnosed and checked by the dealer?
All done and no issues?
My car recently had the check engine light on, but then it went off after a day of driving.
CODE P052E and CODE P052E71when I used my scanner.
I was just in contact with MB Canada and the response below in blue font.
It seems there should not be an issue to get it replaced.

car under an extended warranty because of the ongoing issues with this part.
Check with the dealer before you put a lot of time and effort into this.
I believe they extended the millage and years of coverage.
Hope this helps
