You need to get all codes read first tho to know what's up?
So these are all BMW specific scan tools? Will try to get one of them and see whats going on, not a HUGE deal just annoying and I've been driving this car for a month already (At this point I'm pretty much used to driving with no speedo, my e36's didnt work either, but that was a much easier fix)

Thanks for the links will try them out when I get home

that is all the fuses in the car the rest are relays hidden under glovebox and engine, but there isn't one for speedometer

Same Problem - No speedometer

1999 328i, 5 standard transmission / 5 speed with M-54 eng.

110 K miles

Speedometer quit. No MPG / Avg MPG.

RPM and other gauges are functioning normally.

No instrument cluster warning lights illuminating.

DSC functions

Fuses are good

Car runs good otherwise.

Could it be an ABS sensor or vehicle sensor on transmission ?

Open to suggestions.

Speedometer not working (NO warning lights on dash) Cluster issue?

Is the coolant temp all the way in the red too? If so then it sounds the no CAN bus communication.

Temp gauge operates normally. All other gauges seem to function normally except odometer, and those computerized readouts that require a speed input like the MPG.

Seems like a speed sensor, but which one ?

Do all four wheels have speed sensors ?

Is there a speed sensor on the standard transmission ?

If one of the wheel speed sensors were bad you would get a DSC light on the cluster letting you know there is a problem. So replacing the sensor won't do anything. The DSC module takes the 4 wheel speed sensors, but only the rear left sensor is signal conditioned and sent to the cluster. It is that signal that may be bad. Usually because of a bad DSC module. You can check on the back of the cluster X11175 pin 19.

Thanx

No DSC light illuminated. Other cluster gauges seem to be functioning normally.

I'll start by checking sensor cables and connections, then will change the left rear sensor attempting the cheapest possible item in the process of elimination.

Hopefully it will solve the problem. If not, perhaps a new DSC is in order.

Thank you scottjoh

The sensor is fine if you don't get a DSC (or ASC) light.
Like I said before the DSC (or ASC) module takes all the wheel speed sensors, but, only the rear left one gets signal conditioned and sent off to the instrument cluster. Search for signal name F_DFAHL in the WDS. It comes from DSC module connector X18303 pin 10 (I don't know where comes out of the ASC) and goes to the cluster black connector X11175 pin 19. If you have factory equipped navigation it goes to the GPS module also and is used for dead reckoning.

Scottjoh, I've noticed that as I drive the car and the fuel gauge moved down with fuel consumption toward the 1/4 hash mark, the gauge slowly oscillates up to 1/4, and down to near "E" then again moves up... It seems to continue moving very slowly up and down. The reserve light occasionally blinks. This is a newly noticed symptom. As I said, the vehicle is an early 1999, and is equipped with ASC not DSC. I'll let you know how the speed sensor change affects the situation. I do appreciate your guidance.

Likely a bad fuel level sensor.

Like I said before changing the sensor won't do anything!

For fun I disconnected pin 19 from the back of my cluster and drove around. As I expected no speedo and no mpg.

Hi guys.

Sorry for hijacking this but I can see Filipg92 never came back to tell us if he fixed this and how ....

I have similar problem with an E46 328i from 2000 where the previous swapped the cluster.
I coded VIN, Mileage and everything i the cluster and EVERYTHING seems to work fine EXCEPT for the analogue speedometer. No ABS no DSC lights.

I connected with Inpa to the cluster and I can read speed.
Then to make sure I read speed from correct place I even cut the wire on pin 19 that comes from the ABS module , and as soon as I cut it , Inpa can not read the speed anymore. So ABS seems to give me the signal I need.

Checked with Inpa also all 4 ABS sensors, they all read good.

For info : OBC does seem not to work also (this is next problem I will hunt) and the OEM stereo is replaced by some aftermarket navigation system.

Any idea what can cause this mysterious problem ?

Thanks in advance.

Wow I missed some of these replys..

No worries feel free to hijack I am still driving around with no speedo. Lol never met up with @scottjoh to check the #19 pin. And I have not checked it with the impa.

Wondering now if my cluster has ever been swapped.. I don't think so though, leaning more towards the bad wire.

I'm in the LA area (Torrance) and am available weekdays after about 7pm or Saturday mornings.


I checked pin 19 on my car just to verify what the signal looks like. First I tried looking at it with a portable oscilloscope with the cluster removed. There was no voltage on the wire. It needs to be probed with the cluster connected. The cluster provided the pull up for the signal. I then added a 33K pull up to 12V and got a nice 50% duty cycle square wave with frequency that varied with wheel speed.

I will be in Culver City in 12-22 June Maybe we can look at yours while we have a cold beer )

But still something is really strange about this.

Filipg92 : Does your DSC button work ?
When I press mine nothing shows on the dash.. so I am thinking previous owner changed maybe also ABS module or something else....
I've been banging my head on this for the past 3 days

Do you have a shop? If so what is it called? Let me know, maybe I'll even try for tomorrow morning. (not sure if this will work but my number is 847 962 0510) call or send me a message if you can.

Yes my DSC button works, I have definitely turned it off for some drives. When you press the DSC button the light right in the middle of your dash should come on to indicate that its disabled.

Any you have no ABS light on?

Yes definitely! Maybe by then my speedo will be fixed..

No, the ABS light is not on.

Filipg92 > did you manage to get a bmw scanner ?
Would be interesting to see some readings / errors registered by the cluster or abs if any.

I don't have a shop, but, my friend does. Ex BMW trained mechanics that got sick and tired of the BS replacing stuff that didn't need to be replaced, but, the helpful service advisor talked the customer into it to get up to at least $1000. My friends shop is Silver Star Mercedes (and BMW/Mini) on PCH in Harbor City. He bought the shop about a year ago from the original owner. 37 years in business doing Mercedes and now BMW/Mini. Talk to James.
Flilip92, I'll see you tomorrow morning about your cluster speedo problem.

Problem solved.

It was a wire at the starter that was melted together with a +12V permanent.
The wire goes from the starter motor to the engine ECU.

So I guess the problem is the same for you Filipg92.
