Did you see the post one page back on this thread about replacing bleed line?
Also can you post detail of your fix? What part and where on the car?
Crankcase Ventilation Purge Valve
I had to have my Crankcase Ventilation Purge Valve replaced. I was billed for 12 hours of labor. Has anyone else dealt with this problem?

Another huge thanks to Metros for coming up with a solution to the PCV purge valve issue. I completed the repair this past weekend using his technique. As has been mentioned previously, there was oil leakage into the connector portion of the purge valve. The van has 56k miles on it and the check engine light has been 'silent' for 50 miles so far...
Did you have to raise the front end or did you do everything from the top?^Congrats and welcome!
Information is everything. They could always look up this forum for clues
I’m curious about what they will end up doing though, probably send it to MB?! Please keep us posted.
Answer my own question. No need to get access from bottom for a GLC-300. Wouldn’t hurt but not needed. Biggest pain is disconnecting everything. Each wire and hose seems to have a different lock system. Be patient, go slow. Getting wiring off the purge valve itself will take some creative work. I made a pick from a flat head screwdriver bent 90 degrees and flattened to reach in to disconnect that wire. Have four #4 hose clamps just in case. Good luckDid you have to raise the front end or did you do everything from the top?
Sorry, you don't have a Metris?. No need to get access from bottom for a GLC-300.
No. The same issue is also common in mercedes GLC-300. I was quoted $2400-$3600 to fix the issue. I used the same part number and process above. Had to make a slight modification to one of the hoses but otherwise exact same steps.Sorry, you don't have a Metris?
so far CEL is gone after two years.
Yeah topside, slow and steadyDid you have to raise the front end or did you do everything from the top?
Thanks for the write up; just got my emissions passed on my glc300. Just shared your summary on the Benz forums.Yeah topside, slow and steady
appreciated
Did you figure this out? Im having the same issue.Now that the parts in do I need to clear the error code or will it clear itself if I drive it a certain amount of miles?
My friend has a interface to clear codes but it won't clear it after I installed the new part. It's still giving the same check engine light
Thanks
David
Yet another $2400 thank you to Metros for solving the crankcase vent problem. It's been only a couple hundred miles but the CEL is still off. Slow is smooth, so all went well. Used Oetiker clamps designed for 1/2" PEX to reconnect the feed line. This is the second valve replacement. The original valve threw a code at 12K. The replacement (comped by MB - a thank you to them as well) coded out at 27K (I don't have far to go to get there). Probably from the same batch. It was simpler to just get the part and do the work than take it to the dealer.
I first had this done when vehicle was under ELW in Jul 2019, Then, a bit more than two years later - guess what? Check engine light comes on. For only CDN$290 codes are read and yup, same crankcase vent problem. Oh dear! That's on you good customer since your vehicle is now out of ELW. So give us the $290 for diagnosing the issue and we'll let you go. Then we'll see you and your chequebook for a 11.5 hr shop visit to repair the same problem we last repaired in Jul 2019. In the meantime, just drive around with the check engine light on, because we won't reset it and you don't have time for another 11.5 hr shop visit b/c you need your vehicle to go out there and make some $$ to pay for repairs. I'm working with the dealership(s) to get this resolved, since this shows very poorly. All the very best for 2023 to everyone on this forum - I've enjoyed reading your posts and sharing knowledge with a fine group of enthusiasts! We're going to make 2023 a great year.
Car Wizard did a video on this issue. Highly critical à la Doug DeMuro, but he explains the ridiculous design (tying in multiple components into a single assembly) which in turn jacks both the part(s) and labor cost.I first had this done when vehicle was under ELW in Jul 2019, Then, a bit more than two years later - guess what?

Has anyone associated this issue with cold climates? Maybe kind of a recurring theme for our Spanish vans.
I don't know why car wizard says it's underpowered. Sure the Metris isn't a race car but mine seems to get down the road just fine. Maybe he had it in eco mode?
My guess is because he’s one of those “car experts” that doesn’t understand the difference between HP numbers and useable, real world torque.I don't know why car wizard says it's underpowered.

The car wizard is a good mechanic capable of following technical manuals, improvising a little, and being thorough with doing repairs. He also appears to be fairly ethical, which is nice.
He is NOT a car expert, a car reviewer, a person capable of evaluating a product for a use case that doesn’t apply to his person, or apparently grasping that car enthusiasts (and other people) have reasons for making less than rational decisions (e.g. me investing several times the book value on repairs for my ‘95 E300 diesel because it is of emotional importance to me) that doesn’t make them inately stupid (or unaware of their own irationality).
I have yet to find YouTubers, even competent ones, who don’t have limitations in their perception. If you have use for the Metris’s particular benefits, it’s a fantastic vehicle. If you can’t comprehend the usefulness of a very safe, large, weight capable, good handling vehicle that can do a u-turn in barely more than twice it’s length, it’s just a noisy, spartan, poorly equipped, rough riding vehicle with Mercedes pricing.
By the by, after dismissing the car wizards opinion of the overall vehicle, I do agree wholeheartedly with his opinion of the M274s PCV design.

That's why I compared him to DeMuro. I am sure Car Wizard didn't drive the Metris. And he personally loves a Nissan Juke!I don't know why car wizard says it's underpowered. Sure the Metris isn't a race car but mine seems to get down the road just fine. Maybe he had it in eco mode?
I too thought he was way overly opinionated on the Metris. And there is definitely a "cheap big *ss V8" bias as the solution to any durability and power issue. Magic Mike's comments were a bit more pointed for me as he purports to have worked in a SoCal dealership. He focused on the actual emissions issue being a recurring issue across the M274 line, which is believable.The car wizard is a good mechanic capable of following technical manuals, improvising a little, and being thorough with doing repairs.

Anyway, has anyone in a warm climate had the issue?
He seems to over exaggerate the complexity of the repairs. Like the A/C compressor removal. They didn't even have to evacuate it. They pulled 2 bolts and moved it aside.That's why I compared him to DeMuro. I am sure Car Wizard didn't drive the Metris. And he personally loves a Nissan Juke!
I also enjoyed how he dumbsh*tted his way into thinking the drivers' door has to be open to fuel the Metris. Duh.He seems to over exaggerate the complexity of the repairs. Like the A/C compressor removal. They didn't even have to evacuate it. They pulled 2 bolts and moved it aside.
I found that particularly funny since it is standard procedure on almost all modern vans.I also enjoyed how he dumbsh*tted his way into thinking the drivers' door has to be open to fuel the Metris. Duh.
