I have a crypto a3q cluster laying around. I can read a dump from it if you need.

Did you try to use a s3 8l dump?
I have to say that not help  I tried more eeprom dumps from S3/A3 without success. Behavior of ESP button was same as on A6 eeprom... I tried also recoding ABS unit to S3 but without success too.. I have a crypto a3q cluster laying around. I can read a dump from it if you need.
Thanks for offer but its not needed  I found zip where is bunch of (non)crypto dumps from A3/S3... |

So its not related to epprom , as you see there something with cluster communication with abs/esp.
Maybe go for vw cluster - they communicate with esp by can. Audi cluster in c5 have communication by wires

Yes... But I thought A6 and A3 cluster is physically the same and difference is in SW only...

- 0x270 (8x1 map) - 16 bit LoHi conversion between fuel tank sensor and fuel in litres (I am not sure how to tell if axis at 0x250 or at 0x260 it used [0x288/0x298])
- 0x290 (8x1 map) - 16 bit LoHi stepper motor map for fuel gauge
Hi all, I'm trying to linearise the fuel gauge on my Golf Mk IV cluster with VWK501 software. Looking at both maps above I can see that they are not linear, I do get the non linearity at the bottom but not at the top. I believe the non lienarity at the tp is the reason for the dash to show "full tank" for quite a while. Am I'm correct that for a linearisation I need to amend the map at 0x290? |

Is it possible to change the boot screen in a 2001 audi a4 vdo cluster?? For instance If I wanted it to read something other than press brake pedal to start vehicle??

Hi, I've activated needle sweep in 5N0920872C, this is NEC+24C64, it works nice but only needles are illuminated during sweep, illumination of scales goes on only after sweep, is it possible to activate full backlight during sweep too?

Not possible
its is possible but need a full read of MMU not just the simple data read and then decompile it but the time it takes is pointless |

Reflash with r32 dump or change software coding Have same issue here. Used 1J0920846GX dump, but gear number doesn't appear. Is there any software coding to apply in this case or there's no chance to show it? |

Can anyone tell me if it's possible to modify a crypto C5 Allroad EEPROM? Or will the cluster only accept variations of factory calibrations? To give some backstory, I'm installing a 02X transmission in my Allroad (behind a BHW diesel engine), and since the 02X has no speed sensor, I was thinking of mounting a hall-effect sensor to read the dips in one of the axle cups as it rotates. This would be very simple to setup, but only give me 6 pulses/rev, which is lower than what the cluster expects (about  . Based on info in this thread, I've found where the K-value setting is located in the EEPROM, and I've figured out how to use that spreadsheet posted earlier to update the checksum. If I modify the EEPROM and flash it, will that be enough to get my speedo reading accurately with that kind of VSS setup? Or will I also need to find an early non-crypto Allroad cluster to make everything work? |

Use vss output from abs module. Google it.

I don't think the ABS module in my car has the necessary output; I have already researched this extensively. I know that some C5s did come with the 5.3? units that have the output (same hardware as far as I can tell as the B6 A4), but as far as I can tell, fitting that unit would be a lot of modifications; brake booster, master cylinder, front brake lines, and wiring are all different from my Allroad (compared to an '04 C5 in the local junkyard with the newer ABS). The newer system has the control module mounted directly on the pump, while my Allroad has the control module inside the car, so the wiring wouldn't be a simple re-pin either as far as I can tell. Do you have any knowledge of the VSS output pin on the older units? I haven't been able to find anything documented, even looking at the navigation system wiring diagrams as well. |
