I updated the wiki page on replacing the cabin air filters with a series of 25 photo illustrations and some text that describes the process.

This is something that every 94 or 95 owner should do every couple or three years.

Click here to view the Wiki page on the cabin filter.

Hope this helps. Total time is about 1-1.5 hours.

Cheers,
Gerry

In the event anyone wants to retro-fit their pre 94 with the filters, this is a good instructional doc on how to do it.

Rik, I really don't recommend trying to retrofit the 94-95 filters on to a 86-93 vehicle. When installed as shown in that Japanese document on your website, it will interfere with the main air flap (not allow it to close all the way). I tried this once, applying vacuum to both chambers of the main air flap pods, to see the flap fully closed (wish I had taken photos). That's why MB had to fully re-design the entire heater box, including making the fan cages smaller, to allow room for the filters above the box.

Instead, I would recommend the JR Fitler solution, which mounts externally. It's a little more expensive but probably works equally as well, and only requires a fraction of the effort. I have these on my two pre-94 cars:

Hi Dave.

Could you please provide more info regarding these filters (supplier, price , fitting instruction, how well they work)?

Do they fit behind the little black grill, or on top of them ?

Mercedes used a solution of this type (Dave's filters) as early as the 1960s on the W111/112 and W108/109 cars.

I didn't have any problems with the filters or clearance or any functionality problems.

I do like the JR filters, they are just impossible to find and too expensive.

Did you buy them from japan ?

Well sure, but you also didn't apply vacuum to both ports on the main air flaps with everything taken apart to observe the operation before & after installing the filter - now did you?

You can buy direct from JR, but yes, they are expensive.

They snap in place over the black plastic inlet. They work fairly well, AFAICT... they get dirty, which I suppose means they're doing something, and keeping dirt out of the evaporator. You can buy them direct from JR in France, but they're not cheap. It's probably better to buy 5 or 10 and then re-sell the extras to your MB buddies to offset the cost of wire transfer payment, etc. They are small & light so the shipping cost is almost the same for 1 or 10:

From: INFO JR <info@jrfilters.com>

Hello
We have no distributor in the USA.
We can send the filter directly to you.
Filter #421 is 34.00 euros.
+ sending cost of 21.00 euros.

Thanks for the info. I'll try contact them, to see if they have a distributor in our area or in europe (other than France).
Might be able to find it cheaper.

The maker of the aluminum cross-strut support bars is Wiechers Sport of Germany. It is specific to the 500E and 400E (V-8) cars. They are not all that expensive; we had it shipped here to the US from Germany and it was not too expensive. This was about 5 years ago.

If you Google you ought to be able to find it.

Hi Gerry.

I just checked out their website. Nicely priced !
Though I am not familiar with their effects. is it to reduce body roll ?

It tightens up the front end just a hair... similar to installing a slightly larger (+1mm) sway bar. I have one on my 1987 300D.

Postby gerryvz on Tue Feb 17, 2009 9:27 pm

It tightens up the TOP END of the strut towers and keeps things stiff from the top end. I think it's a nice complement to the bottom-end reinforcements (i.e. larger anti-roll bars). I've had them in VWs and such that I've owned in past eons and when I can get them, I install them.

Of course, some cars need them more than others. MBs are pretty structurally sound so probably don't need them as much as other cars do. Incidentally, mine may be coming up for sale in the near future as I will be purchasing and installing Austin's upper strut mounts. I think those will have far more benefit than any crossbar.

Cheers,
Gerry

What do you mean your cabin steams up? Is the a/c on or off?

I don't know if the JR filters have charcoal or not, if they do then they filter dust and odor, if not, then only dust.

Thanks - I think I'll get a set.

What I mean is, as soon as it drops below about 10 degrees celcius, when I have my windows up and A/C off, the windows steam up very quickly. By that I mean I wouldn't be able to see anything within 10 minutes. Also, I start to get condensation between the two pieces of glass of the rear window.

===================================

Postby Glen on Sun May 03, 2009 4:22 pm

At that temp, the a/c should dry the air enough inside the car to keep the windows clear. What happens when you use defrost mode?

What I mean is the windows steam up WITHOUT a/c. As soon as I put the a/c on it clears everything up nicely. When I drive my dad's Honda in the same weather conditions, the car does not require the a/c to be on as there is no condensation. It's not such a big deal.

I don't think I have the defrost a/c mode as I have the twin dual zone dials. If you're referring to rear window defrost then that doesn't work on my car. I just get one feeble little clear line across the middle about 1cm in width. Does the whole rear window need to be replaced to get this to work again?

Chappardababbar


===================================

Postby Glen on Sun May 03, 2009 7:48 pm

Oh, I understand now. To minimize condensation on the inside without using a/c, make sure you are using fresh outside air, do not use the recirculation mode. You may also want to vent the sunroof or lower a couple windows just a bit. The reason for the condensation is the drastic differential in temperature between the cabin and outside. Once those equalize, your windows should stay clear.

Bummer the Wiki photos were lost... any chance you still have them floating around, Gerry?

Re: Wiki page on replacing cabin air filters (1994-95 models

Here are the photos from the replacement of the W124 cabin air filters. This only applies to E500s and all other W124 models for the 1994 and 1995 model years.

I have annotated each photo with a caption describing it. :relieved:

Total time for the job is approximately 1-1.5 hours, if you take your time.

Cheers,
Gerry

Re: Wiki page on replacing cabin air filters (1994-95 models

Quick tip - only the one side has to be disassembled to R&R the filters, as shown below. Slide the bottom filter out first, then the upper filter will slide down (out of the clips) and then out the side. The two filter halves will nest together, make sure they are properly connected to prevent unfiltered air from entering the system.
