MAF question

[Kyiv]

Is there a difference between MAFs for variations of M119 engines? I purchased a remanufactured Bosch MAF for my 400E from FCPuro several years ago. It has part number 0280214005. Looking online, only 0280214004 comes up for W124 M119. Part ending in 05 is mentioned as for W140 M119

 

[gerryvz]

No. The MAF is the same as used with ALL M119 engines with LH injection, of both 4.2-liter and 5-liter displacements. This includes the W124, W140 and R129 chassis with LH / M119 engines.

I would not use the Bosch part number for reference generally, as it is probable that the Bosch part number changed during (or after) the production of these cars. Instead, I would use the MB part number.

MB generally appends a two-digit number onto its part numbers to indicate a refurbished part. In the case of the M119/LH MAF, the original MB part number is 000 094 01 48. The MB part number (last known part number) for the refurbished MAF, which is all that has been available from MB in recent years, is 000 094 01 48 80.

At the present time, the MAF for the LH / M119 is NLA from MB. It appears difficult to find them new on the aftermarket, as well. Used MAF prices for the LH/M119 seem to be starting at $200 and going up to the $400 range.

I have six M119/LH MAFs in my basement parts stock. All of them carry the MB part number 000 094 01 48, and the Bosch part number 0 280 214 004. Two of them are rebuilt MAFs.

Gerry, would you be willing to part with one? My '92 needs a new one.

 

[gerryvz]

I would, but they are not tested, and thus I cannot guarantee that it would work. Perhaps another person like the @gsxr who likely has tested spares, would be a better option? I just don't want a buyer to be disappointed on such a critical part.

 

[makemann]

Appreciate that. I'll check in with him.

Hey Gerry, I'm having trouble finding a remanufactured MAF for my 1992 500E. I've ordered two used ones without luck. I'm wondering is anyone rebuilding these still? I've been searching online for 000-094-01-48-80. I found one that was 000-094-07-48-80 and others ending in 81. They all say will work on the 5 Liters but I suspect newer 5 Liters. P.S. Glad, I found this site. I have not posted anything yet, but I feel like I've read this board from start to finish. Really appreciate all of you on the site sharing what you know. -Matt

000-094-07-48 is for 1996-up M119's with Bosch ME injection. It will not work on 1992-95 models with LH injection. Completely different design.

Robert Fenton has what's claimed to be an open-box remanufactured dealer MAF 000-094-01-48-80, for $600/obo on eBay (link).

Used ones are available for half that or less, just make sure the seller accepts returns in case of DOA. Need to test by viewing live data on SDS after installing.

A forum member in Texas reported that Injection Labs in Colorado can rebuild the M119 LH MAF for $350. Another forum member sent in their MAF last year but they returned it due to "family emergency"... might be worth contacting them and see if they are currently able to repair them or not.

 

[gerryvz]

That Fenton MAF on eBay is already sold.

 

[gsxr]

It sold within the last hour. Was it matzbats?

 

[northNH]

FWIW I recently sent a working 119 MAF to Gibraltar (PO lady wondered “Is that a state??”) for $125 plus, surprisingly, only $25 shipping (if she got that right).
I’ve not yet heard back if it made it and if it enjoyed the trip.

Any idea what Cardone charges to rebuild an MAF? I can't find it on their site. I have a dead MAF on my parts shelf.

I was told $350, if they can do it.

Fenton must have a bunch of these things. Previous one (#3?) sold for $600, another is now listed for $700... and the "make offer" button has been removed.

Oh, I saw your post... was just checking to see if you were still reading the forum!

I am curious exactly how many he has. Is this the last one, or are there 2 dozen more in the closet which are going to be listed?

I want to say that there were at least 10-12. It's been some years since I saw them.

I have not been on the forum as much lately, but fortunately some other key members like @cascade and @xfadmin have been on the case.

 

[Eno]

Has anyone seen an original boxed MAF for our 036’s that does not have the Mercedes-Benz logo and number on the plastic part but it is a Bosch part number.
This is a Mercedes-Benz boxed and part number NOS MAF but Bosch inside the box.

 

[Duh_Vinci]

Please, help me understand something... From what I know, the remanufactured MAF for M119 has not been available for some time now (000-094-01-48-80). so from what I've seen, there is updated part 000-094-01-48-81, at least, is what classicparts.mbusa.com/ showing me. However, when I plug this updated part 000-094-01-48-81 into the search via partssearch.mercedes-benz-classic.com it does not come up at all.

So, is 000-094-01-48-81 available or not?

Regards,
D

Definitely will check tomorrow.

That -81 part number came after a message "000094014880 - discontinued part, however this one is available 000094014881" or something along the lines... from classicparts.mbusa.com

 

[Duh_Vinci]

So as of now... My brother just called me, he just spoke with parts dept:

"There is no source of these rebuilt MAF (or new) at least, not from MB dealer. No stock in the US no stock in Germany. And that part number, 000094014881, while it is a valid part, updated from 000094014880, and is (was Bosch rebuilt unit), no longer available as of 06/12/2021 through MB direct.

If it is available (that is a possibility) then only through Mercedes Classic, they are separate entity..."

With that said, 2 questions:

Does it sound right? I thought Mercedes is Mercedes, classic or not, but NA at local dealers yet maybe available through Classic?
Discounted prices through Naperville and Covington, does it mean if I place online order, it will likely be canceled?

D

Are there any other sources for doing this?

[anderzen]

What do people do if MAF fails and a replacement or rebuild cannot be found? Bypass and tune for speed density somehow?

Used ones are easily available on eBay, for now... that's probably the best source. Unfortunately, you need an SDS (or other digital scanner) to confirm if the readings are normal. Otherwise you have to just drive for a few hundred miles and see if there are no fault codes and the engine seems to run ok-ish, at least compared to the old/defective unit.

Fenton had a half-dozen or so NOS dealer remans on eBay earlier this year but those are all gone now.

There are ~20 for sale on eBay right now, mostly in the $200-$300 range. Make sure to check the return policy and/or warranty before buying. Most sellers won't have any test data to prove it works so you're stuck verifying if it's good or not.

Are you CERTAIN the MAF is defective? The only way to confirm 100% is to view live data with the engine running, but a persistent fault code for the MAF indicates it's probably bad, assuming the harness is not original *and* the engine runs better with the MAF disconnected.

Ya if i unplug the air mass lol it runs like its 1993 and she just rolling off lot put when I plug it back it hiccups every so often like she about to die am Hoping it’s the air mass cuz I have changed everything else coil packs new wires Distributer and the rotors with new plugs then I finally unplug the air mass and she runs like new

 

[aliking]

Hello all,
I just want to ask what it means if the engine shuts off when i disconnect the MAF?
I tried to disconnect the MAF while the engine running and the engine dies, i tried to switch on the engine again with no luck till i connected the MAF again.
I think i have a problem in the wiring harness

 

[King13ls]

so let’s say the harness is fine when cold everything works normal but when at opperating temp could the heat cause the solder to disconnect or something? Cuz I’ve had the same issues with my maf although my cars runs better with it disconnected,,,

1984 MERCEDES-BENZ500-CLASS​

Also my local junkyard currently has one of these and I just want to double check and made sure the maf are the same I saw on the previous post that’s said all m119 4.2, 5.0 use the same maf but like did they make it different in 84 then a 95 maf? Or are they all the same?

 

[King13ls]

Also are these harness worth buying?? Last time I had checked there were like 20 of them now there 2

They ARE NOT the same. Not even close. 1984 is a different engine (M117) and different injection (mechanical CIS). You must use an MAF from an M119 with LH electronic injection. The numbers need to match between your old & new MAF.

Don't buy OE/Genuine parts from PartsGeek. Please. Buy directly from one of the online dealers. For your 1995 E420 the engine harness would be A1244401906, $320 with free shipping from Naperville, or $290 plus S&H from MB Laredo, for example:

If your engine harness is old with crumbling insulation, replace that first and see what happens.

 

[King13ls]

I’m learning, that’s for the information, I checked the harness it said it was replaced in 10 and I was looking at the cables that go to my injectors because those are visible and they look fine, but I was reading on here about someone saying how there harness looked fine but when they were replacing it the wires were all bad , but thanks for the patience’s and help it’s very appreciated

 

[gsxr]

If your harness has been replaced, with no insulation failure, it's fine. Check the date code on the tag to confirm. The replacement harnesses should have wire that looks brand new even when 12 years old. Search the forum for photos of what the bad stuff looks like. Can't get them confused, they look completely different...

 

[King13ls]

Harness is ordered, will update once it’s here and I’ve replaced it and c what happeneds,,, I should reset my codes when before I replace no?

That harness has a 2009 manufacture date on it. It shouldn't have needed replacement. I've never seen a replacement harness go bad. You may have spent money needlessly on a new harness.
