YIKES. Well, at least it seems clearly visible . . .

bobblehead

that's the intent

SEXYBEAST

no leaks here, just had my b3 service

called dealer yesterday to try to determine which direction/color to go, Service Advisor checked with tech and I was told DO NOT USE any dye as they have their own way/chemical addition to determine if the leak is due to a faulty RMS. Apparently they clean the car up underneath real well, pour this stuff in (wish I'd have written down what he told me) take it for a decent drive and apparently that'll indicate whether the leak is due to RMS or not . . . is this just 'dealer talk' or is this a legitimate reason?

bobblehead

No worry. If the dealer has done this tracing method many times, then just leave it to the dealer to investigate.

I am just relaying on how my dealer has approached my issue by using this color dye test.

just a quick update if anybody is curious: Took car to local dealer yesterday, they did their testing process today and I just got off the phone with the service guy where I got the bad and the good news . . . the bad news is the RMS is indeed leaking and the oil/air separators are backordered so I'd have to wait for them before repair can be completed, the good news is apparently I got an extended warranty when I purchased the car in '19 . . . embarrassed to admit but I completely forgot about that little fact so the repair would be covered in full! All I have to do is pay for the front brakes and have them do a B service while car is there as the previous, independent shop I took the car to didn't quite do all they were supposed to . . . right now I'm doing a tiny little happy dance in my living room well, brakes & a new windshield as just last weekend, driving back from a getaway, a big rock hit the lower left corner and pretty much destroyed it . . . but I'm not complaining as thats covered by insurance! Did I mention the happy dance?

bobblehead

Wow. You dodged a bullet indeed ❤️

They are doing front pads and sensors only ? Front rotors are crazy expensive if you have to replace.

once again I'm happy to be a part of a group of passionate individuals sharing their experiences, frustrations etc . . . I would have never found a reasonable resolve without it . . . now I have to figure out how to pay for the brake job . . .

Nice you have it covered under warranty. Did they give you a approximate date for the oil separators? After I had the RMS done on mine by that ****ty chevy dealer I talked to a Benz dealer and they said separators were available except for 1 of the 3 vent lines which was on backorder. They said the vent lines could be re-used but it would be a good idea to have them instock incase they break upon replacing the separators... It was going to be approximately $2300-$2500 to do the separators.. I have not done them and just been driving my car with plans to sell before the 1 year warranty from the Chevy dealer on their RMS repair that they botched (didn't bleed cooling system correctly, didn't plug in auxiliary cooling fan for engine or transmission, car was low on a quart of oil) is up. The more I drive it though the more I want to keep the car, but I can't get out of the back of my head the fact some Chevy mechanic tore this car apart after it was hand assembled in Germany by someone that actually cares.

Silly thought unless the cars are crap and dead after five years? I’ll be a happy 213 owner one day and aftermarket thrives after the first gen owners give up their cars. Your statement makes it seem as though the aftermarket does not support older cars and the reality is exactly the opposite of that. Silliest post of the day. Expect the most amount of real development of this platform from secondary and tertiary users for about another ten years. Pretty sure the aftermarket won’t be thinking about the new ev platforms for a very long time.

Pads, rotors caliper bolts & new sensors . . . front brakes are @ 3mm needing to be done now . . . rears are @ 5mm so I can wait a tad longer on them . . . they certainly are not inexpensive and I keep going back and forth between factory & aftermarket but I don't have a decent shop around here that I would trust with the work so likely will be going the factory replacement route . . .

The fact that the oil separators are on backorder could be an Indication that the demand for these parts is exceeding repair projections. I wonder if the parts are also being re-engineered to eliminate the failure points. I still haven't seen and reports in this forum about model years of 2020 and beyond.

Insight into this can be gained if someone has access to the parts catalog which shows revision history. Revisions suggest MB knows there is a problem and is making changes. This was the case for the well-known and widespread oil-in-harness situation with cam sensors and cam magnets.

I would love to know what revisions are being made, and any updated part numbers for the oil separators. My 2021 hasn't shown any signs of leaks, yet, so I am interested in obtaining separators for future installation. It doesn't seem prudent to me to use the original parts past 15,000 miles. I'd much rather pay for those to be changed than deal with the car being out of service for an extended period. My confidence in the dealership pulling the engine and transmission for the repair without causing a new problem is low.

On mine ... dealer replaced the right & left air/oil separator with this following part #

Left - 177-078-54-00 mb online part sites say this replaces 177-078-14-19 and 177-078-30-00

Right - 177-078-55-00 mb online part sites say this replaces 177-078-15-19 and 177-078-31-00

So, the question is are those parts on mine now have made some sort of design or functional changes ??

sixfive

those are factory parts?

chassis

Part number change means “something” about the part has changed. Seems like MB is going down this road given the changes noted above.

Agree with preemptively replacing separators with the latest part number, if what is on the car is not the latest.

bobblehead

MB OEM parts

so when my dealer orders new separators, it'll likely be the newer ones I imagine? Doubtful I would have any control over that . . .

bobblehead

You can ask your Service Advisor to tell you the part # .... my replacement was done back in Jan 2023, so I would imagine these are the latest.

bobblehead

to add ..... my vent lines have no prior part #
