Title: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 09, 2016, 11:27:40 AM Hi, im experimenting with a cluster i found on the junkyard.. I have this attached PDF of the "Blue" 32pin connector but where is the 12V+ supply and ground... In other words how do i fire the damn thing up.. I have an idea to use this in an old car and cpntrol signals via an Arduino.. :)

Terminal 31 - ground Terminal 30 , 15 and s-contact - +12V Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 11, 2016, 08:45:41 AM Ahh thanks ill try that and report back...
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 11, 2016, 08:47:46 AM Heres the pinout description. i found.. hmm.. not sure if this is correct but i looks very similar to my cluster
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 11, 2016, 08:56:03 AM Terminal 31 - ground
Terminal 30 , 15 and s-contact - +12V Did not work :( Title: Re: Post by: macxxx on September 11, 2016, 10:33:11 PM In your pinout there is no terminal 15 or scontact - the voltage that shows up afer turning the key
Maybe it starts by can bus? Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: macxxx on September 12, 2016, 03:46:56 AM i am almost sure that it needs a wake up signal from CAN BUS - you will need a gateway and who knows what more....
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 12, 2016, 07:15:11 AM Yes im on that path too...
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: f1torrents on September 20, 2016, 01:11:46 PM There is a Can Signal that needs to be sent out every 100ms to keep it awake.
It can be emulated.... Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 21, 2016, 01:35:25 AM Aha what kind of signal is that, is it a code string?... I have an Arduino where i can send what ever i want if that method works.

I have an Arduino where i can send what ever i want if that method works. If you have a CAN bus analyzer util for your arduino, you can capture the message and see it yourself..Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 21, 2016, 12:12:58 PM That message would come from the ECU right? I could use my China Can tool to se what it gives med if i connect that tool to the ECU CAN high and Low.
Title: Re: Post by: macxxx on September 21, 2016, 12:15:54 PM And not from the MCE?
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 21, 2016, 12:43:43 PM Also found this i one is not sure of pinout but this dont really 100% apply to this cluster if compared to pics i posted above.

Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Jim_Coupe on September 21, 2016, 01:02:47 PM Thanks f1torrents im trying to send the message via cheap china USB2CAN device.. not sure how reliable it is.. It blinks one time when i press SEND.. om also not sure about the PinOut hmm but I think i have +12 and ground connected correct.. The CAN bus "Twisted Pair" was also easy to find.. but when I apply 12V the cluster blinks one time and the needles starts to move to "0""..
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: f1torrents on September 22, 2016, 01:04:44 PM Send the signal every 200ms
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: bennyboi on October 11, 2016, 05:11:01 AM i use a canbus for these, just go to a scrapyard and get one from an 8p audi, they wire up to +12v, ground, ign, canH and canL then canH & canL to OBD plug and just connect cluster to power and canbus :)

Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: eliotroyano on April 16, 2017, 07:40:33 PM Friends sorry to take this post from dead, but does the "Bordnetzsteuergerät" or Power Supply Control Module is not needed ??? ???
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: macxxx on December 07, 2017, 01:21:44 PM I'm planning exactly the same - how did it workout? , I will try to power It up using gateway and column control module ( i hope it sends ingnition signal thru CAN )
Title: Re: Audi A3 8P cluster 32pin pinout?

Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: macxxx on December 08, 2017, 11:20:11 PM Ok thanks for info.
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: H2Deetoo on December 11, 2017, 01:19:47 AM You don't need any modules, if you can send the correct canbus messages at the correct intervals.
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: macxxx on December 14, 2017, 10:06:07 AM I dont have any can bus sniffers , can you tell me what is worth buying?
It was cheaper to buy a Borndnetz ( less than 10$ ) So I have it all connected on bench - Bordnetz , Gateway and cluster - I can communicate with them using VCDS , the Bordnetz sends signal after switching ignition ( 12v on terminal 15 pin in G connector ) , but the clusters only lights up clock and odometer What did I do wrong? In measuring blocks the can works ok, and no can faults in any module Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Mikhail on December 16, 2017, 06:46:28 AM Which fuel level sender is fuel pump side? I have slight doubt that how well suction jet pump works, so I coded cluster to fwd to read only one level sender to be sure how much fuel is at pump side but does it now read at pump side?
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: macxxx on December 16, 2017, 11:51:34 AM maybe take the fuel gauge sender 2 pin out of the connector and you will be sure
Title: Re: Audi A3 8P cluster 32pin pinout? (experimenting) Post by: Mikhail on January 11, 2018, 12:28:37 PM A little OT but quattro fuel gauge works also with one fuel level sensor and can be sure that how much fuel is at the pump side. Side effect of this is that at when the car is resting the tank sides does level themselves and when start driving the fuel gauge start to climb when suctionjet side is pumped to pump side.
