No one has a w201 here?

probably involves making some custom instrument cluster removal tools..

I.E. coat hangers with a strategic bend at the end...

then fish them up in between the crack of the dash hump and top of the cluster body and find the clips....

then pull out ...

Never did it with a 201 but on the w123 I know that I have to push some spedo cable slack up so it will come out easier and disconnect the oil pressure feed line as well as the other connections.


do a search for other info.

I ca pull it out about an inch or so but I think the speedo cable is holding it from behind. How do I release the speedo cable? I tried accessing it from below but it's impossible as there's to much stuff down there.

You're supposed to disconnect the cable from below. Don't ask me how though - I tried removing my cluster once (there's dust in it & I wanted to clean it) and I eventually gave up.

In case you don't have a copy, the service manual says:
The instrument cluster is held in place by means of
five spring clips located on instrument panel.
1 Remove cover under instrument panel, left.
2 Remove hose (arrow) toward lefthand lateral nozzle
from below.
3 Unscrew tachometer shaft on instrument cluster
from below.
4 Push out instrument cluster from the rear.
5 Disconnect electrical connections and line for oil
pressure gauge, remove instrument cluster.

If you figure out how to remove it, let me know!

Looks like I need a crowbar .

Thanks for the info. I don't have the service manual.

I have an '88 190D. My approach was to remove the panel under the steering column. A nudge from behind was enough to get things moving and I was able to pull from the front. I removed the speedometer cable and a couple of large electrical connectors and the whole thing swung out.

The main difficulty I remember was disconnecting the speedo cable. I have read suggestions to disconnect at the tranny and feed slack through the firewall so that you can get a little room to get your hand in.

When you put it back in, that's the only way I could reconnect the speedometer cable.

I don't remember any issues with the tach.

Here's a couple photos from my removal effort:

I had a lot of problems trying to use coat hanger pullers and pushing it out from underneath. For me it's way easier and quicker to pull out the dash speaker and push the cluster out from above.

I''ve done the 190 cluster several times. Remove the left-side vent first, work through the vent opening to R&R the speedo cable.

Be careful to NOT break the panel around the courtesy-light switch when removing the vent assembly.

This discussion has been very helpful as I just had to do this today (broken odometer). I disconnected the speedo cable from the transmission and started the cluster out by pushing form underneath, then pulled it out. Not too bad, lots to disconnect and whoever commented on the sharp teeth in there was right on the money!

I would definitely reccommend removing the cable at the trans, although I haven't tried to put it back in yet. two questions -

1)Does the cable just bolt back into the tranny, and should I lubricate the cable with something when I have it out?

2) Any insight on the size bulbs used for general dash illumination or a number?

Thanks
George

Perhaps, but I still side with the simple 3-minute left-side vent removal method, keeps you out from beneath the car also.

How do you remove the left-side vent? Do you mind posting pics?

Hi George
Can you elaborate on how to remove speedometer cable at the tranny

I know this is an old thread, but I finally found the patience and time to reattempt the removal of the 190D's instrument cluster (with success this time!).

1) The approach of removing the left side vent didn't work for me. Through the side vent, I could just barely fit my arm in and touch the speedometer cable. But, the opening is so small that it wouldn't allow me to tighten my muscles to grab the cable connector. I'm not a giant person or anything - the opening is just really tiny.

If you want to try this anyway, to remove the vent, put some cloth around the tip of some needle-nose pliers, grab the center horizontal divider in the vent, and pull straight out. It's just a friction fit. Then pry up the 4 clips holding the plastic trim in place (2 at the bottom of the vent opening, 2 at the top). Carefully pull the plastic trim out a little bit, disconnect the switch, and then remove it the rest of the way. Reassemble it all before you put the cluster back in. If your arm fits (or if you can recruit a small child or recent famine victim to help out) then this is probably the easiest method.

2) What worked for me was to go under the car and remove the two plastic retaining clips that fasten the speedometer cable on its way from the transmission to the cluster - one was directly under the transmission and one was part way up the side. You don't need to actually disconnect the end of the cable from the transmission. Removing the retainer clips gives just enough excess cable to allow the cluster to be pulled out so that you can reach the connector on the back of the speedometer. From the engine compartment, you may need to push some of this new excess cable into the passenger compartment; a rubber grommet thing keeps the cable from feeding through easily.

There's enough spare cable to allow you to loosen the connector, and more importantly, put it back on when you're done, without bruising and mangling your arms.

Don't forget to reconnect the retainer clips when you're done.

I cleaned the bulbs, got rid of the dust, and cleaned all of the electrical connectors. It looks like new now!
