Is it possible to read EEPROM of instruments cluster without k-line?

[voboyoy606]

I have a VW Polo 2002 Hatchback. I need to swap the instruments cluster over, although my model doesn't have k-line in the pinout for the cluster. It does however have convenience CAN low/high, can I still read/write to the cluster?

Its a 9n1? You need the bcm....

A Body Control Module (BCM)? I am new to this, how would that help me with reprogramming the EEPROM of the instruments cluster? From my research, I could read/write the EEPROM directly if I connect to it on the board but I know that is dodgy and would prefer not to risk it

Why don`t you post pictures of dash?
Bcm has nothing to do with cluster...

Here's my attempted wiring diagram to get CAN bus communication with the VAG K+CAN Commander 1.4, although I haven't had any luck. Maybe I am using the wrong config or something? I think I have to send some data to CAN WAKE, but I'll need to packet capture the car to do that unless it's a generic set of packets?

You need to disassemble your dash and see what type of eeprom it is.
Then connect to it with a usb to serial adapter.

It is a 93C86 EEPROM (full marking: 93C86W6 KF02F). Online people suggest a lot of products. Doesn't sound like this EEPROM can be read/written by a standard cheap serial adapter. Any suggestions for cheap readers and writers? That is assuming I can't read it through the CAN BUS somehow

Get upa usb. Or TL866 minipro, Xprog, if you want to do this next time and a long time

Had a look into those. I already have a Raspberry Pi Zero, so I am going to try this library to save buying something new: https://github.com/nopnop2002/Raspberry-93Cx6.

I got VCDS Lite installed to support my third-party VAG K+CAN Commander 1.4 (USB). No luck connecting to the cluster still, but I think once I capture CAN bus packets and replay them, the cluster should come to life.

If anyone has any idea if I can make the cluster wake up with the 'CAN wake up' pin, let me know. Can't find any documentation.

If you search on forum, you can find this. Get the pinout and solve your problem

Hi
Did you find a solution for this?
