I've been getting an intermittent CEL, P0410 and P0171. I Recently had my car in the shop for a B Service and while it was there the mechanics supposedly changed out two vacuum lines as part of the recent TSB. Well, this is one of the lines that was supposed to have been changed, right?? Anyway, this line is right under the air box, and is only visible with the air intake disconnected and pushed out of the way.

Fortunately, the line is long enough, I just cut the end off and re-attached it. I Put dozens of miles on the car, and a few starts today, and no more CEL. I'm headed to the Little Rock dealership on Monday to discuss this.

What do you guys think about that???

Typical. If it was you or I, one might understand it, but these guys are supposed to be pro's.
(Not)

Typical - be hard on them

if you have a printer- take the pics with you. they are the type of turds who would call BS on you. it still amazes me- the dealers have the highest labor rate around, yet a lot of times (not all the time) they have the least amount of skill

I've been told on another forum that this hose isn't one of the TSB hoses. I'm not sure, got some research to do.

Apparently, however, this hose was broken while they performed the TSB work... whatever work they did, or did not do, I began having problems 2 days after the B Service was performed, and it seems it was this hose, split and leaking in air, all along...

That hose isn't one mentions on the TSB, but it certainly wouldn't be the first time I've seen that hose split like that. Pretty common, no TSB from MB about it, not really an issue apart from the fact that it has been recently worked on.

The small vac hose on the otherside for the headlamp adjustment can also split like that.

At this point it's probably not worth your additional time to go complain.
Nice Magma red sedan! Don't see those very often.
Is that you in the fighter jet?
Are you a pilot?

Well I'll be there to pick up some parts, so I'll discuss it as planned. They called a bad MAF to fix the CEL, and obviously never looked at the engine first. I think they may have damaged the hose in the first place when they did the B Service...

Yep, that's me in an F-15E.

Interestingly myself and the head tech are having a compitition to see who can correctly diagnose the first failed AMM/MAF sensor on a M271 engine at our dealer. So far niether one of us has found a failed AMM/MAF sensor on any M271.

We have found leaking breather hoses, intercooler hoses, cracked intercoolers, split vaccum hoses (like pictured), damaged headlamp adjuster, cracked intake manifold, leaking secondary air injection valve and 3 faulty control units (they were VERY interesting!). Never a AMM/MAF (yet). I've seen heaps on any other engine, just not a M271 yet.....and they're bloody expensive!

I don't know why I took their advice on the MAF, I just assumed they were going on more info than I had at the time. I assumed they were doing things the right way, and knew what they were doing...turns out they were just guessing with my wallet, and unfortunately I don't give them so much credit anymore.

I'm certainly not saying that they can't/don't fail. I have yet to see one myself.

They will fail eventually, but they seem alot more robust than in other MB's and therefore alot of other things should be eliminated/checked before replacement.

Ausmbtech - are you here in the states? Your shop sounds like a shop I would trust my car with ...

Sorry, I'm in Australia

No, I'm sorry.

Do you have a link to the TSB?

I sure don't. Everywhere I look, it seems you have to pay for those things these days... anyone?

Dude! That red is smokin!!

Ummmm...Top of the w203 forum, guys? There is a sticky for the m271 recall AND a separate sticky for TSB's.

Ummmm.... that is a list and doesn't detail the TSB............

The original question was if there was a link to the TSB. I was just pointing out that there is a list of them.

As for the details, someone else will have to chime in because if this isn't connected to the m271 pcv hose recall, don't know.

The conversation was about a link to the contents of the TSB. Why would he ask to see it on a list? To what end? Lets not quibble Drex.

Thanks! I like it

Not tryin' to. I'm just saying that the list of TSB's shows a number that you could bring to the dealer...that's all.
