Easy 2.5" bixenon upgrade for DEPO audi a4 b5 facelift headlights

If you like to upgrade your projector assembly in DEPO headlights for facelifted Audi A4 B5 for whatever reason here is a simple solution:

you need this 4TL-R 2.5" projector


https://www.aliexpress.com/item/32759121526.html

these are also available from other sources, but I did not test them and can not tell if they are same.

and also here:

Next, you need the template for drilling which can be brought from my tindie store:

https://www.tindie.com/products/tomaskovacik/template-for-25-bixenon-depo-audi-a4-b5-lights/

With this template also comes document with detailed instructions on how to modify the projector to fit. It requires 4holes to be drilled into projector and made few cuts to clear inside of headlights.

Here are some sample pictures:

fixing wiper motor JL 52372

If your wiper motor in V.A.G. car with part number JL 52372 is continuously running (probably as result you leave it on while blade is frozen to window :) )  most probably the chip inside is fried. If so, nee chip can be sourced on aliexpress: https://www.aliexpress.com/item/32958082771.html . After soldering chip in place, everythings works as it should.

Few pictures from module:

REFLASHING BM62 to 2.1.3

https://github.com/tomaskovacik/IS2020/wiki/Upgrading-firmware-on-BM62


P2_0 and P2_4 pulled to ground

EAN pulled high directly to VDD_IO (this is required even that datasheet stated there is pullup!)

22uF cap on VDD_IO (check erata)

5V connected to 5V

gnd to gnd

rx to B10 of stm32

tx to B11 of stm32

run isbtflash.exe

select com port, speed 115200:240 hit connect

browse-> select firmware files:

hit update button

after the restart of the module identify in EEPROM_tool as IS2064S_012_SPK02_V2.1_BETA

unfortunately, EEPROM_TOOL is not able to upload a new EEPROM patch created from

UITool_IS206x_012_DualModeSPK_v2.1.25_UI_Default_Table.txt or UITool_IS206x_012_DualModeSPK_v2.1.25_BM62_EVB_UartEnable.txt

and IS206X_012_DUALMODESPK2.1_E1.0.4.1_1214.bin

"Device's IC version doesn't match File's IC version: IS206X_012_DUALMODESPK2.1_E1.0"

reading the second post in this thread https://www.microchip.com/forums/m1046854.aspx I just remembered about stupid EAN PIN!

PULL P2_0 and ENA DOWN DIRECTLY TO GROUND! reset! -> IS206X_012_DUALMODESPK2.1_E1.0 !!! VOHO!!

write new eeprom, do not forget check "Load default in into IP" on third screen of MPET.exe

code for stm32:

#define BLUETOOTH_EEPROM_UPLOAD PA4 //goes to P2_0
#define BLUETOOTH_FLASH_UPLOAD PA5 //goes to P2_4
#define BLUETOOTH_EAN PA6 //goes to EAN
#define BLUETOOTH_RESET PB14

void setup() {
  Serial.begin(115200);
  Serial3.begin(115200); //Serial3 => TX = PB10, RX = PB11
//  pinMode(BLUETOOTH_EEPROM_UPLOAD, OUTPUT);
//  digitalWrite(BLUETOOTH_EEPROM_UPLOAD, LOW);
//  pinMode(BLUETOOTH_FLASH_UPLOAD, OUTPUT);

//  pinMode(BLUETOOTH_RESET, OUTPUT);
//  digitalWrite(BLUETOOTH_RESET, LOW);
  delay(100);
  digitalWrite(BLUETOOTH_RESET, HIGH);
}

void loop() {

//  delay(1000);
//  Serial3.write(0x01);
//  Serial3.write(0x20);
//  Serial3.write(0xFC);
//  Serial3.write(0x00);
//  Serial.println("responce:");
//  while (Serial3.available()) {    // If anything comes in Serial1 (pins 0 & 1)
//    Serial.write(Serial3.read());   // read it and send it out Serial (USB)
//  }
//  delay(1000);
  while (1) {
    if (Serial3.available()) {    // If anything comes in Serial1 (pins 0 & 1)
      Serial.write(Serial3.read());   // read it and send it out Serial (USB)
    }
    if  (Serial.available()) {     // If anything comes in Serial (USB),
      Serial3.write(Serial.read());   // read it and send it out Serial1 (pins 0 & 1)
    }
  }
  //delay(100);
