Having removed my instrument cluster recently I thought I would post a "How to" for this job.

Tool list :
1. T20 1/4" drive socket and ratchet.
2. Small flat bladed screwdriver.
3. A plastic card ( American Express is good because no one accepts over here.lol.) or similar.
4. A pair of long nosed pliers.
5. A very small torx key

Firstly you will see 2 self tapping screws which hold the cluster to the dash board at the top of the binnacle. These are size T20 torx screws and I used a socket and ratchet to loosed them and used the socket to screw them out with my fingers.

This is where the credit card comes in, you need to slide it between the lugs which the screws fit through and the outer housing, moving across both sides to ease the cluster out of the dash, I also had a small screw driver as a lever to help.

When you have the cluster free of the dash move it to the right side. At the rear of the cluster there are 3 wiring loom connectors. These are colour coded, blue, black and white and these correspond to a blue, black and white sockets on the instrument housing. The connectors are locked in by a lever which you have to release to allow the connector to be pulled out of it's socket. Each connector is locked in the same way and you can see clearly on the blue and black connectors that there is a small "button" which you have to press down on in order to push the locking lever out of the way. Once you have disconnected the white plug you can pull the cluster much further to the right side which makes unplugging the blue and black ones much easier.

Once you have the cluster off and on the bench (kitchen table) you can remove the instrument control unit from the binnacle by removing 5 very small torx screws with the key in the tool list.

The original one from my car, black housing for the control units. The three larger green bulb holders contain the main gauge illumination bulbs so I fitted new ones of these as a matter of course. They are 3W rated 501 type bulbs.

This is the one I got from Andy @spurs fan in a coupe for a very fair price, and although the different coloured housing meant it would not be a simple swap over, it was the housing and front (glass) that I needed. Once you have removed the 5 screws the black or green housing will lift off leaving the front part of the gauges still attached to the main housing (the bit I needed - so you have to split these).

In the previous picture you can see 3 black plastic posts which have a white plastic collar around them, the are what fastens the gauges into the main housing, to release the gauges you need to take your long nosed pliers and turn the white plastic collars through 180 degrees, then you can lift the gauges out of the main housing. Leaving the three component parts. This where you would have to get to if you wanted to fit some white dial faces available on line @Mint. Also, like me you may find that you will have to swap the coloured plastic strip with all the warning light icons along the bottom of the instruments. This is easy to remove by gently levering it off the (6, I think) little plastic locating pegs.

When you refit the gauges into the housing make sure that the Temp gauge is set below zero as when you turn on the ignition it will shoot up and read about 1/2 way to normal before even starting the engine. I found this out the hard way!

Now you can reconnect the wiring and place in the dash aperture, but don't yet push it all the way home. Here you can see that with the ignition on the Temp gauge is at the lower limit.

After road testing, you can see I did 8.3 miles to makes sure all the gauges work OK and all the warning lights functioned as they should. When you're happy you can then push the cluster all the way home and refit the 2 T20 screws. Job done.. Hope this is of some help. Any question please feel free to ask.

Tony.

Great write up! If you get the pictures large on your screen you can used the program 'snipping tool' and capture the picture. You can also draw lines on the picture to illustrate exactly where you are talking about. Save the pix as a .jpg and load up. The pix will be small and load really fast compared to normal .jpg's as well!

Works assuming you are using Windows. I throw this in because I was struggling to understand exactly where you are referring to. Thanks for sharing because I wanted to remove the plastic front of mine but could not work it out. :) Now I know.

Oh, I rate this as a 1 spanner out of 5 in difficulty! LOL :)

I concur, great write up and thanks for sharing. On the spanner rating I'd put it down as a 20 for me. Needed a lay down once I'd read it=))

@t-tony - the beauty of this forum for me is that somebody has always done it (no matter what the particular 'it' is) before I have.

The previous owner of my Z3 has obviously done this before me but rather carelessly left behind a dead fly that sits annoyingly just behind the glass. My job for tomorrow is to dismantle and remove it.

Photo attached of the offending fly posted in case anybody is an expert and wants to tell me what particular type of fly it is (other than a dead and annoying one).....

Thanks for the post even though it was a while ago now - its still very useful for others and very much appreciated

I had to replace my cluster with a used one recently because of a coding plug failure rendering the instruments non-functioning, and no odometer. Unfortunately the coding plug has 80k miles more on it than my car so I need it corrected before my next MoT. This is proving difficult. I also have a tamper dot showing which is ironic as the mileage is vastly too high not too low!

Actually I swapped the coding plug from the Ebay special into my cluster so all I really needed was the plug but I didn't know that at the time.

Write up made this a breeze. I’ve just taken my cluster out as it’s still partially steamed up, the odometer is barley lit, the temperature red light is on and the buzzer in the unit is intermittently sounding and to top it off bleeding dead bugs behind the glass so will need stripping as well.

Tony,

Many thanks for posting and documenting the disassembly of the cluster. It will be invaluable as I am trying to figure out how to enable the cruise warning light. PS, I found it helpful to take off the kick panel and gently push the instrument cluster from behind. Inserting tools between the binnacle and instrument cluster did not work for me.

Couple of these affixed to the glass front will aid pulling it out. should find them in the domestic area of a hardware shop or supermarket.

I took mine out yesterday and once the two screws had been removed, it pulled out easily without any other tools. The dead spider is out but I couldn't put it back in as the BMW dealer didn't have the bulb I needed!

That's a shame Steve, but at least the wildlife got turfed out. Which bulb was it?

One of the beige 1.5W ones. He didn't phone me yesterday but hopefully will have it tomorrow.

Thanks again for the write up. They make a huge difference when you're doing these jobs for the first time.

Stupid question of the day:

If you replace the instrument cluster does it take the odometer from the ecU or is it held on the cluster? Same question goes for service light count down.

I swapped the parts from my old binnacle into the "new" one.

Okay, so to make sure I understand, you wanted the face plate, the glass enclosure and the inner face plate in front of the gauges.
Thanks Tony, that is a great write up.
