It is time to give an update about the BMW e46 Digital Gauge Cluster project. The whole team worked hard, and we made some significant progress. - See more

ID4Motion E46 Digital Gauge Cluster



To start, the hardware.

With the hardware, everything is finalized, with some minor details to be solved. The final order from the metal housing will arrive this week and is made 5 KM from our shop. The injection mold for the cover is finished, and the first batch will arrive in the paint shop shortly. We have the correct E46 connectors that will plug into the wiring harness. For this project, we will use our in-house PCB designs and the same automotive display we use in the E90, true and tested on 500+ BMWs right now.

K-Line to RXTX, is the only thing we have to decide.
We have to intergrade a K-Line adapter to the Digital Cluster input to convert it to something the gauges can understand. The preferred way is to do this is directly in the wiring harness. (If someone has any good tips?....)

The install.

The installation is a thigh fit (watch out not to scratch your dashboard with the corners of the cluster.) But it will fit without cutting any part of your dashboard.

We will use the already exciting mounting points for the installation from the cluster. The two bolts will go true the cover and display bracket, with some extra room for adjustments. The bolts will secure the whole unit, with the lower part of the cluster fitting snug to the bottom of the dashboard.

We are working out the signals.

We are making great strides in decoding all the signals necessary.

Because they're a lot of different variations of the E46, we can't measure everything on our test vehicle, so we need to borrow some models to complete the list.

If we are missing essential pieces, please let us know.

Features


The E46 will keep every functionality the original gauge cluster has, including all the tell-tales it can show. But also new extra's


BMW E46 Backup camera
You will be able to add a backup camera to the cluster for a complete view of your surroundings.

BMW E46 G-Force sensor
A G-Force sensor is implemented for braking, accelerating, or taking hard corners.


BMW E46 Cluster Night mode
We implemented a Night mode to be more visible to read in the dark. 


BMW E46 Digital Cluster Settings

And many more settings to change, like the appearance.

The Timeline


1. Starting January 2022, our test vehicles will drive around with the cluster and give it a shake-down.

2. Early on in February, we will invite 20 test drivers to be the first ones to drive around with it. Testing will be for a reduced price incl. All the features, in trade of feedback.
(Applications will start on the last week of January)

3. If the 20 test drivers are booked, we will take on preorders (Delivery will be after the major bugs are solved)

-It will be great if there will be external analog inputs so we can add the extra sensors without having multiple external gauges
-I wish it will have some sort of a design studio to alter the gauge design, for example

I’d like to get on the list of testers, I’m a shop owner and currently own 4 E46’s so I can test in multiple E46 variations if the cluster is compatible with each of them. 01 330ci, (2) 02 325xi’s and a 99 323i.

It looks so modern and it is wath i was looking 4 years ago for my e46 … 4 years ago i tryed to make an digital model with a company from poland. They gave up at one point and didnt continue with it. But NOWWWWW this great hard working team appeard and made one of my dreams come true. Im glad that someone thinked about e46 and did something very good. Im waiting the final product with much pleasure. Keep it going. Good luck.

I own a 2004 coupe with nearly all the tiny little features. I drive roughly 4400 km per months and I have the Resler stick too. So if the price is fair, I could do a lot of testing and comparing to the data provided by the RESLER interface. I agree with Panagiotis – if you can implement all necessary features on the cluster – it will be more than a fair price for.

Hey guys,

i watch this project since the beginnings now and congrats to the progress, great work and product. Now my question is, is it possible in future to become this clusters also for e39 too, when it working on a e46? Because in base is the same hardware and bus system in these cars specially on the facelift cars, or wolud this never becom true.

I have a e39 with M52B28TU engine which is in base the bigining of the M54 engines on the most of e46. Because a dream will become true to modernize the e39 interior.

Im from swizerland and here are a lot of bimmer guys with the be loved older models, which would say take my money please!

Regards

Danijel

Great stuff! excellent progress. Heel goed! Can you include the analogue style fuel consumption indicator? It’s always been available in all BMW’s except some ///M models and turbocharged vehicles. Some of us(like me) drive M54B30’s and those things use a lot of petrol!

Most of these readings can be done with k-bus. Resler’s usb interface with the ibus app on android can do them all via kbus (speed,rpm,coolant temp, fuel liters, doors/windows open and a lot more). I believe it would be wise to at least talk to him and see if it’s a better choice to implement just the kbus to get all data. IF the refresh is good enough for the cluster to work properly.
Oil temp I believe can be read only on M models and station wagons. On sedan I got for eg. nor oil temp not oil level can be shown. Only the low level light is shown if it drops.
If the price is right though, I’d love to be on the testing or even alpha/beta stages since I do over 2000km/month and the car has some extra features that can be tested with the cluster(cruise control, auto headlights, auto wipers). Also I can test it against the reslers interface, or even send you the usb to give it a try. The cost of it if you can implement it on the cluster will be fair compared to the total cost of such a cluster.
