In my 1997 E320 Temperature gauge, Fuel gauge, Speedometer and Tachometer have gone dead. When I turn the key in the ignition none of the gauges work. However, the temperature gauge has some minor vibration/shaking which you can feel when you look closely. Also, light sound comes behind the temp gauge when it is vibrating. This sound is like a very small motor trying to turn this gauge.
I have checked both cluster panel fuses in the fuse box under the hood and they are good. But when I removed either one the temp gauge vibration stop and the light sound which comes behind the gauge also stop.
Digital Odometer, trip odometer, clock and outside temperature are all displaying/working fine.

Does any one knows what’s really wrong with it and what's the fix.

Thanks a lot

Those

are the cluster fuses,#4 and 7?at least on my 99 thats what they are.The gauge and instrument fuses I think are unlabeled over under the big panel that contains the ecu on the passenger side by the duo valves.Several fuses along the leading edge if you pull the 4 screws and lift the cover.Pull each fuse and check with a multimeter set to ohms.zero ohms no resistance =dead fuse
always pull the fuse to test.

I replaced the following two fuses in the Driver Side Fuse Box under the hood but no change
Fuse#4 Instrument cluster, automatic climate control
Fuse#7 Instrument cluster, automatic climate control, relay module / motronic

Passenger side big panel under the hood
I checked all 5 fuses like you suggested and they all look good. I tried to use the ohm meter but on every ohm setting it gives me zero on every fuse. May be I am not doing it right but they look good.

What should I do next?

Thanks again

Cluster

I would pull out the instrument cluster and check the connection of the cables. Your car has two cables that come behind the cluster and I think one (or both !) of them might have gotten loose. Thats what I would check.
Just pull your cluster out, it simply slides out if you can find a good place to grab it.

And then check the wires where they are connected with your cluster.

If I pull the cluster, disconnect and reconnect the both cable, will I loose the odometer mileage or it will stay. I don't want to loose the odometer mileage because there is no problem with the odometer.

No

Don't worry, you will not loose the mileage on the cluster.

Even though a lot of people wish they could.

I think one of your cables is loose. If you can't get the cluster out, there should be a DIY w picture in here somewere.

Let me know if you have other questions.

I connected the instrument cluster with out the outer shell and turn the key in the ignition. I noticed that all the gauges are still dead and the temp gauge has still minor vibration. I gave it a little push with my finger and all the gauges started working.
When I turn it off and turn it back on with out restarting the car, all the gauges gone dead again and they only work when I give little push to the temp gauge.
If I turn it off, the temp gauge keep vibrating few seconds and the temp gauge small motor make a light noise/sound.
I think the motor that turn the temp gauge has gone bad. Is it possible to fix it my self?

Thanks in advance

Sounds like you have either have cold soldering or a microscopic crack on one or some of the cupper leads on the instrument PCB (Printed Circuit Board) Check for bad solder joints or crack with a magnifying glass.. Solder joints deteriorate by the time if protector layer worn off of PCB surface. If you are good at soldering, solder the joints you think don't look good. I would also check the pin surfaces for any possible corrosion. Also make sure the socket pins tightly fit the mating section.
Make sure nothing is electrically short circuit before putting back the instrument cluster.
Good luck.

Boy do I feel you pain, I am having the EXACT same issues. Needles not working but the info panel still functioned. I went through all the stuff everyone suggested on here sans the soldering to no avail. So I ended up pulling it and sending it to a professional in North Dakota who specializes in VDO clusters.

He ended up not being able to fix it. He said one of the four needle motors was bad and that when one doesn't work, none work. He basically told me that the cluster needs to be replaced and I believe a new MB cluster is over $1K.

Sooo with that in mind, I have always wanted a data logger and code scanner. So I bought the Scan Gauge II and it provides all the info you need and acts as a code reader/clearer to boot. My gauges work one out of every 5 or so cranks and so I got used to reading the scanner mounted right on my cluster in the times it doesn't work. Shoot I look at the ScanGauge even when the needles do work! It can be used in any OBDII car and I love it. I also love the price of $169.

Some on here may call me crazy but it was an inexpensive fix and I am totally addicted to all the other variables and functions it can do.

So if you are ok with it sitting in your cluster, you won't be disappointed. I can disconnect it anytime and use it on my other cars too. Good luck:thumbsup:

I have a spare cluster that everything works on if you want to use it for parts. It was out of a 1999 E55 and all I pulled the AMG faces and needles off of it. I am not sure of the miles on the odometer. You can talk your dealership in to resetting it to your actual miles. PM me if you are interested.

I had a similar issue temp,fuel,tach speedo and the odometer stopped working. I open the fuse box on the drivers side ubder the hood. While the car was running I removed fues #7. the car staklled and everything in the cluster went nuts. I turned the car off and replace the fuse. Everything works fine. It seems like it reset something.

I had the same problem with all needles not working and temperature indicator needle vibrating.I have tried all on this and other site and nothing. I came up with a permanent fix for less than a dollar!!!! Do this: Open up the instrument cluster and plug it in without the cover so you can play with the needles. As the temperature needle starts vibrating hold it with your fingers, you'll see all the needles start working. Permanent solution use a rubber cone/cylinder glued with thin double side tape to the instrument cluster so that it acts like a door stop to prevent the needle from descending, needle should rest on the rubber stop and indicate 70 degree C. From now on needle will start indicating only from 70C and up.When you put the ignition ON needle will start vibrating for a second and the all the clocks/indicators will start working again. I have this done in my car 96'W210 e320 for over a month now and works very good! MB wanted to charge me $1000 for new cluster...others in North Hollywood wanted $500 minimum to fix it. I had a rubber cone with double side tape on the bottom about 1.5 cm long with a 0.7 cm diameter base that was used a base leg for a device, get creative and will look good ...Good luck and please post your results so we can help others too !

hey Tim ... one question, all plugged in, when you turn on the lights, do the cluster / dash lights come on? ... if not, then it's apparent that the cluster connectors are giving you the problem .... but first, when you reconnect do you move the lever until it clicks into place? ... that' the final pressure on the connector to secure it in place and form a tight contact ... also, look inside the contact on the cluster side, see if there is some grime buildup and ensure it's clean ....

if that's not your problem, then get some contact cleaner/dielectric grease (parts stores have little $1 pouches of them) and smear over the contacts before plugging them in .... that should ensure clean contact ... good luck!

I fixed it

I fixed the exact issue in my 1997 e320. just removed the motor of RPM (the one that shaking) by de-soldering it, and now all other gauges are working, I'm going to order a replacement motor and install it.
I hope that helps:smile
