Cabin air filter?

[036]

Who can authoritatively and conclusively answer the question whether these cars have cabin air filter or not?
I´m asking cause....."some say" cabin filter was an option till 5/92 ( both cars were made couple of month later ), some say there must be code 305a, 580 or 581a ....

B778591 and B849026.

Huge thanks in advance.

I've never heard of a MOPF1 car with dust filter, ever. AFAIK the dust filter first became available with MOPF2, around June 1993 production.

Is there any evidence of a MOPF1 car from the factory with the dust filter?

Both those VIN's are mid-1992 production, well before MOPF2. There is not a specific option code in the EPC datacard indicating dust filter. [Edit: I don't know where code 305A would appear - on a build sheet for the car perhaps?]

 

[2phast]

My late production 93 did not have the filter, although I built and added my own.

Both have code 855, so called half restyle, with 2 series (mopf1) technik, we`ve discussed that lately.

I don't recall the 855 discussion, only found these 2 old threads which indicate 855 might have been cell-phone related in the W124?

Wait, I think you meant this thread from a year ago:

I have a VERY hard time believing a 02/1992 production car would have the dust filter. Not saying it's unpossible, just really unlikely... anyone own one of these unicorn MOPF1.693145 vehicles with code 855 between 02/1992 and 05/1993 that has a dust filter? They don't exist in USA but in ROW, anything is possible. -ish.

My 11-93 build has cabin filter

Correct - all facelift (MOPF2) cars, probably as of 07/1993, will have the dust filter.

The mystery is the MOPF1 cars with "half restyle" for about the 1 year prior. These don't exist in USA.

He he.... there were 1475 car build. with 855. Jelmer had one.
Ok, let´s say no filter, thanks a lot.

what's a dust filter

 

[r44raven]

Not sure how relevant this is, but my B913271, Belgium delivery, built late 1992, has a cabin filter.
No indication on the data sheet that this was an option.
It shows 855, but this would seem to relate to a phone.

Ah, interesting! This is the first I've heard of a dust filter on a MOPF1 car. That VIN doesn't have code 859, so it shouldn't be MOPF2.

Was @Jelmer's car also confirmed to have the dust filter? That would be at least 2...

Can you please show photos of this? Even a close-up photo of the cabin blower fan area would be good.

It is 100% certain that ANY car with a facelift grill, is going to have cabin filters (US or rest-of-world). Perhaps there is a clue in the ISPPI or EPC as to when the cabin filters were phased in, in terms of a VIN.

I believe that dust filters may have begun being installed in cars made in the early spring of 1993 as a phased-in running change. This means that perhaps the latter 25% of cars made before the 1994 change-over / facelift, could potentially have dust filters.

Perhaps the blower motor and/or housing and/or blower motor regulator part numbers would be an appropriate break, given that the regulators were different between models with and without cabin filters (and for ROW cars, whether they had automatic climate control or Tempmatic).

I also believe that no US-spec cars had the dust filters UNTIL the formal facelift / change-over in the late summer of 1993, to the 1994 US model year. Don't think you will find any US 1992 or 1993 car (pre-facelift) with dust filters.

One other question - for the pre-facelift, non-US cars confirmed to have dust filters ..... were they equipped with Tempmatic or ACC (or either)? Wondering if an early phase-in of dust filters in spring/summer of 1993, would have been specifically associated with one type of "Euro" climate control or the other.

 

[gsxr]

Perhaps the blower motor and/or housing and/or blower motor regulator part numbers would be an appropriate break, given that the regulators were different between models with and without cabin filters.

Gerry, that's what I would expect also, but the EPC only specifies With/Without dust filter - no option codes. Very odd, not Mercedes-like to do this.

Sample screenshot below, all the components that differ have the same footnote without option code or VIN break.

Confirming that is exactly the same data as in the ISPPI.

Perhaps also we can check other components associated with the system, such as the temp sensor, blower motor housing, and so forth to see if there is a VIN-specific break in one of the other parts that are exclusively tied to cabin filter, or no cabin filter.

So far, every component I've checked that differs between the two (with/without), does not show any option code or VIN break.

I had always assumed that the break point was MOPF1/MOPF2 (i.e., when the new style hood/grille appeared) since that is what we received in USA. Apparently there may be some Frankensteinian versions built during the preceding year...

 

[036]

1. No idea if Jelmers car had dust filter.
2. For now my information is - from 5/1993 all cars have it. Before 5/93 only with code 305A, 580 and 581A, optional.
3. I´ll try to figure out how many cars previous to 5/93 had a filter.

Thanks!!
855 in case of 500E has nothing to do with phone. 855 is previous to 859, full facelift. 855 is only new technik, old body. I guess you do have both mirrors electric and mb star in a grill, not on a bonet, do you? ))

 

[gsxr]

Interesting that B913271 (12/1992 production) has the dust filter (Staubfilter), but does not show codes 305A or 580/581 in the datacard. It does have code 855 though!

The 855 is indicated on a Datacard print out I have - from information (I think!) from EPC version 2.0.1.1 02/2015. Against the entry is the description "19990311 - TEL.TELEAID AT "UPPER CENTRE CONSOLE" NOKIA.D.NET.
There is also a second entry of 855 which lists a description - 19960619 - V140 M119 MIT NAG (43 FZG).

I don't know what the second 855 translates to, but I think it has been proved that the phone description applied to the first 855 is incorrect?

By the way, my car DOES have the star on the bonnet, but only because a previous owner facelifted it )
And both mirrors are electric!

About gerry's request for a photo of the cabin blower area, the car is currently still in its winter wrapping, stored away. As soon as I get it out, I'll do a pic!

 

[036]

Yes, in case of 500E - one of many (damn) small and bigger changes while production time. Might this be intersting?

PS Happy i was guessing correctly about your 1 of 1475 "half facelift" car, 855 still scares our american friends to death

 

[Rouven036]

My relatively early '92 production car has a dust filter...

 

[036]

It looks like ( we still checking) there are 5-6 cars with non automatic climate conditioner and cabin air filter.
Only 1 car have code 580, body colour 702 (smoke silver) + 075 (fabric beige), also have filter. Interesting is that this car is also 1 of 1 colour combination, 702+075.
And many many cars with code 581, automatic climat control....
We talking previous to 5.1993 or B988928..... I´ll be back.

 

[gerryvz]

That is my research theory — that filters were phased on starting in the spring of 1993 for non-US models. Perhaps as early as March or April.

 

[Rouven036]

I will check my SA codes later and post them, it's a manual AC car. Built 2.92

 

[Rouven036]

These are the SA codes:

Also looking into the SAA Codes (like auxillary list of items required for the fitted options) doesn't identify anything regards to the dust filter.
HVAC core for manual AC with dust filter is A1248307860

 

[036]

Before B988928 :

305 - 87 cars
580 - 1 car
581 - 3958 cars ( There are 7917 cars before B988928, so nearly half of all cars before 5/93 were with filter.)

Are we certain that code 581 indicates a dust filter prior to B988928 ? Seems like a LOT of cars to have this, especially when nobody seems to have noticed until now?

And, Rouven's car has none of those 3 codes, but still has the dust filter.

 

[gerryvz]

Generally MB codes are the same for any given chassis/year/market, worldwide. You cannot have a code that denotes dust filters for one car sold in one market, and another code for cars sold in another. A code is the same, worldwide. It is either present, or not present.

The list of codes in my MB PKW-Verkaufen-Taschenbuch, dated October 1990, shows the following:

Code 305 - not shown in book. Another reference shows from 1-November-1990, that this is indeed a Dust Filter code
Code 580 (Klimaanlage / air conditioning) - standard at no extra cost. Code must not be prescribed. List price DM 3,910— for non-500Es.
Code 581 (Klimatsierungsautomatik / automatic climate control) - available as an option. List price DM 790— for 500Es.

What this means is that 500Es could be delivered with non-AC by specific request at no cost; or A/C (Tempmatic) as standard at no cost; or with ACC at a 790-mark extra cost. No wonder why so many non-US and non-Japan cars were spec'd with Tempmatic, but not ACC. The US didn't get a choice, it was ACC or nothing.

The real code to hone in on here is the Code 305, which indeed does specify dust or cabin filter for the W124 and other chassis, after late 1990. I still do not believe that any 500E built before the spring of 1992, would have cabin filters (perhaps unless it was a special request, hence Code 305 being present on a 1991 or 1992 500E?). And all cars built after the MOPF2 changeover (i.e. generalizing a bit, facelift cars), would come standard equipped with a dust filter.

My best guess is that the filters were perhaps originally spec'd as an optional item (Code 305), and starting in the spring of 1992, began being phased in as a standard production item for non-US-market 500Es, and then later became standard with the transition to MOPF2 for non-US cars and the "model year 1994" changeover specifically for US-market cars.

So, the quest for early 500E models with Code 305 is really where this quest needs to center. What was the earliest car with Code 305? And when and how often/many subsequent cars with Code 305 were made before the MOPF2 / US 1994 changeover?

 

[Bogeyman]

Is there a way to visually check for the filter?

 

[gerryvz]

Yep -- you can see the edges of the filters under the windshield wiper area.

HOW-TO: Replacing HVAC cabin dust filters on 1994-95 model (facelifted) 124 | "HOW-TO" Tutorial Articles

FSM filter replacement procedure is at this link. It references the same 3 codes mentioned above. It seems 305A is the only relevant code though...

 

[Bogeyman]

FWIW - my 05/93 500E doesn't have them and my 12/95 Cabrio does, so that conforms with present knowledge.

 

[036]

What was the earliest car with Code 305? And when and how often/many subsequent cars with Code 305 were made before the MOPF2 / US 1994 changeover?

87 cars. What was the first one i´ll ask.

 

[036]

Very first one with code 305 is B904552, 18.12.1992.
271 512
228 241 242 249 291 300 305 412 441 540 570 592 620 645 662 682 810 855 873 880

Number of 87 is still to check.

I'm late to the show but my 08/92 car has dust filters and manual AC (Tempmatic?). Code 855 is listed on the data card as well.

 

[036]

Great Info Darek, thank you! Would you please share your VIN privately?

 

[gerryvz]

I would also like to see photo evidence of dust filters on all these early cars, so that it can be ascertained that these dust filters are indeed factory and not aftermarket additions.

I"ll post photos later Gerry.

 

[darek_u]

Here are the pictures. Unfortunately I don't have the latest ones, these were taken when I was refreshing/overhauling the windshield wiper and blower motor few years ago. You cannot see the pollen filter in place but it is obvious where it goes. In fact I just replaced filter elements a week ago but never took a picture...

 

[darek_u]

The pollen filter element I used has the late W124 p/n. This time I used FEBI 09445

 

[gerryvz]

Weird, I don't see the two little "L" shaped retainers (one in which you flip up) for the filters on your housing box. Cars equipped from the factory with the filters should have these two little clips. You can see them in my HOW-TO on removal and replacement of the filters.

 

[darek_u]

Yes, you are right Gerry, I don't have these clips... However the filter elements fit perfectly into the case opening. They sit flush and tight, even without these clips. There are no any traces of modifications or home made "solutions" visible - I was 100% convinced this is factory equipment. Now I don't know... Weird... Anyway, I'm happy to have filter, otherwise I would have to figure something out to add an aftermarket one.
Just curious - how does the late blower case look like with the cowl removed? Can anybody post a picture?

 

[gsxr]

Appears the difference may be Siemens vs Behr manufacturing...? I've never seen a Siemens setup here in the colonies.

 

[036]

Darek´s car has no filter in VIN. It was added later.

 

[gsxr]

Do you mean the code was added to the datacard later? Or his car had the heater box with dust filter retrofitted?

 

[darek_u]

No, my datacard doesn't have the 305 code but I do have the filters. Like 036 says it must have been added later. Looking at the HVAC box itself and all the parts it was definitely a professional upgrade, possibly at dealership. Maybe back in the days Mercedes offered a retrofit service? I know that Porsche did this for 944 models - pollen filters became a standard from 968 MY'94. 968 shared a lot of parts with older 944 (HVAC system being one of them), Porsche offered a P&P kit for 85-91 models that added filters to the system. In fact they still offer this kit...
