Not too fond of paying for a lawyers yacht.
Hey Tony3 I am curious did you get any resolution? There is no fucking way I am letting MB get away with telling me no againI haven't written in a while because I was tied up arguing with Mercedes Advocacy. They will not cover the 12 hours labor to replace the intake tube emissions line that contains the vent valve that is not a purchased part # available on the Metris, So now one of my vans still cannot pass emissions, I am turning them into the ANN ARBOR Michigan Dept of federal emissions
This is wrong ! I trusted Mercedes to do the right thing and they failed me!
So now I need to know if there is anyone on the forum who has done this motor mount removal and ECM removal to get at the breather box /oil separator for removal to examine the box and valves that you cannot purchase without getting the whole $900 intake line assembly? I think this is a huge crime..and it does seem to be common amongst other models on the mbusa forum..more so on the M274 engine .
Anyone have experience before I attempt this time consuming job? better from on top or bottom to gain site of this part? I talked to a parts guy who said they are cutting in half a pipe coming above the breather box to cut hours off the job for space reasoning? The advocacy does not have any technical background btw, I tracked these people and they are mostly sales type mouth pieces judged on how fast they can rid you! As if the tire wear problem wasn't enough agony and waste of money for 18 months until they came out with new specs, they have t punish me again with this PO524E emissions failure from clogged pipes and vents!
Please chime in if anyone has done this job? thank you
It was probably that undersized piston wrist pin issue. I was pretty much a hard driver after break-in. Go Speed racer van, Go. I've since mellowed a bit... just a bit.Thats the first I've heard of a M274 dying of low compression/knocking. May have been a parts flaw from the factory.
yep, similar to the check engine that occurs sometimes when the van stalls 30 seconds after restarting a hot engine on a hot day. The fuel pump controller gets confused as vaporized gas through it and faults.Meh, I’ve cleared the code twice. Takes about 6 mos to come back. I’m thinking this is more of a momentary fault, as opposed to an actual broken part. Van runs fine in between.
US emmision waranty law.How did they get away with excluding it from the emission performance and control warranties? Somebody asleep at MB and/or EPA, like the B.S. that my van was held up because MB neglected to EPA certify the 135.
Thank you for the good information, there just has to be a more economical solution.My PCV required replacement at 94503. As I’ve mentioned MB covered 3/4 of the parts cost as a courtesy; no warranty except the ELW was in effect at that mileage, which does not cover emissions parts. I do not know if ELW coverage influenced the courtesy, or simply my long standing loyalty to the brand and the dealership that Worked on my behalf to get that courtesy.
The problem with the design, @pawo007, isn’t basic emissions law. A PCV valve is a very simple and common part (and failure point for that matter); it can be replaced in many cars by a shade tree mechanic for double digit prices. The issue that gets people heated on this instance is that the PCV is only replaced as an integral part of an expensive component that costs ~$1800.
