VW Audi Instrument Cluster Bench Harness make your own (Audi TT, A3 S3, Audi A4, VW Golf, Bora MK4)

In this tutorial, you will learn how to create a budget-friendly instrument cluster bench test harness for various Audi and Volkswagen models, including Audi S3/A3 8L, TT 8N, Audi A4 B6 and B7, Volkswagen Golf Mk4 and VW Bora/Jetta. With the test harness, which incorporates the OBD port, you can easily diagnose and read the instrument cluster using an OBD2 cable and VAG EEPROM Programmer.
VAG EEPROM Programmer is a versatile tool that can be helpful when replacing an instrument cluster. It enables you to copy essential data, such as immobilizer, key, and VIN information from one instrument cluster to another, ensuring that both units are matched accurately.
This setup is straightforward and cost-effective, giving you a reliable connection to your instrument clusters without the need to spend a fortune or visit a dealership for repairs. Follow along with this step-by-step guide to create your instrument cluster bench test harness today!

Just followed your wiring diagram to build a harness for my 2001 TT & various MK4 clusters - it only took about an hour to throw together and test out! Thanks for the insightful video, Ian 🙂

[@ianpgonzaga]

Ahhh awesome! Glad the video helped and didn't take you too long 👌

Another great video thanks for your help Ian!

Thanks Ron 🙂

Hi, Great video, just what I was looking for! I'm just about to wire up a MK1 TT cluster in an earlier CE2 fusebox. Is the FIS completely CanBus driven, or is there a possibility of getting some functions to work? Also can the audible bleeping on the cluster be muted at all (I have a full version of VCDS)? Many thanks

Hi, Great video, just what I was looking for! I'm just about to wire up a MK1 TT cluster in an earlier CE2 vehicle and figured out all the pinouts on the T32 & T32a blue & green plugs to the CE2 fusebox. Is the FIS completely CanBus driven, or is there a possibility of getting some functions to work? Also can the audible bleeping on the cluster be muted at all (I have a full version of VCDS)? Many thanks

[@ianpgonzaga]

Sounds. Like a good project. The grey pin has the 3 signals controlling the screen. When a buttons pressed they short to ground. There are many more signals at the grey pin too for the engine so keep studying the pinout the functions to want working at the cluster.

[@olliyt9718]

hello great vid but do you know how i can remove the key immo on the bench cuz i got it powered upp and everything but i cant get rid off the immo thing i have a skoda fabia 2006 gauge cluster and trying to hook it up on to a pc

[@ianpgonzaga]

So you want to remove the flashing immobilizer light when powered up on the bench? .you can't - it will always be flashing until the system can see all other immobiliser parts from the ecu and the key itself.

What an excellent video, sorry, you don't have the connection diagram of the dashboard harnesses with the obd2 connector.

Hi there mr ian.thanks for this information.i wanna ask if u know what pin or colour wire i can use to tap in on the RPM signal.thanks for this video

[@ianpgonzaga]

Hi. Will be different depending on the car. See the pinout for your car on this page. That should help. wiki.colormfa.ru/installation

[@simeonhadev4062]

So on A4 no need for the blue connector only green ?

[@Veso266]

Did z buy this ports separate or got it from wrecked cars? (What can u usualy find in wrecked car, I thought people would take all the interesting bits (like radio, gateway, other nodules), before u even have a chance to get to the car) I am thinking of just buying a premade harness from china (mine has to have quadlock, obd2 and can gateway port, blue plug would be nice so I get easy acsess to can lines), not sure whats cheaper to buy premade or buy all the connectors separate (and pay for shipping) or buying something premade

[@rogerthat1963]

Great video. Q: I only have the 2 cables (32pin) on my audi tt MK1 8N. Not the 16pin plug. Do I just stick with the diagram or do I need something additional? also: I have seen another video where they only connect the blue 32pin cable to get it working as "ON". Is this correct? Thanks a lot.

[@ianpgonzaga]

So your screen mustn't be full FIS if you only have two connectors. They might be wired up like a golf. So this wiring should work. The 16 pin plug is the OBD connector required to talk to the cluster while in the bench. If you only wanted to power up on bench then only blue is required.

[@rogerthat1963]

@@ianpgonzaga excellent. Yes only need to power up i believe to get the gauges in correct position. thanks so much for your help!

Hi, congratulations for the video, I would like to ask you if, according to your experience, the golf4 instrument panel can be fitted in the Audi A3 8L with the necessary coding. Thank you

[@ianpgonzaga]

Hello. Interesting question but I don't think it will work. They might have different information layouts that A3 might not be able to use. Some thing to experiment with - I have not tried though.

Hi, could you help me? I tried this procedure on my Audi A3 8L Cluster and it doesn't work. Then I tried using Ezp2023+ and now it doesn't work anymore. Do you have the EEPROM file to share? My car doesn't work without the cluster.

[@ianpgonzaga]

Hello! Oh no maybe the wiring incorrect? What step went wrong? Sorry I don't have an A3 file ready.

I got a 2005 tdi engine and ecu on my Tacoma. Can I do a something more new perhaps a digital one?

[@ianpgonzaga]

Isn't Tacoma Toyota? I'm not sure what instrument cluster options there are for a Toyota cluster. It'd be cluster dependant... Not engine and ecu

[@cryptodoge5355]

I have got power to the cluster and Kline is hooked up properly but can't connect to cluster when I read with Eeprom programer. My power supply is 1.5 amps is that enough or do I need more?

12v 5a is what I use

which pin is for illumination?

No need to wire this up - they all light up with the 12v/IGN/GND if it's been programmed that way. Otherwise you test illumination with VCDS.
