 Question before entering: How to build DSG connector for EE & flash read/ write on PCMtuner ? I have built connector as in photos, but it’s not easy to find relay with 720 ohm resistance, i used 320 ohm relay coil resistance to enable L- line power auto control, does it affect the PCM tuner unit? I will try Tactrix open port, also is it necessary to add 120 ohm on parallel for can L&H . Solution: Your pcmtuner has this control circuitry already hence the message would you like to control l line automatically!! The only requirement for dsg on bench is to provide 1 X 12v permanent power hence using a breakout cable ( godiag gt107 gearbox adapter ). There are 2 ways to bulid connectors to read DSG gearbox mirco and eeprom for cloning purposes: 1st method is to read on bench using external power supply (gt107) and it works perftectly. gt107 breakout of gt105 has switched and permanents. With gt107 you need to be able to switch power manually, gt107 has switch. Y

  Question: Got a problem with pcmtuner reading vw dq500 gearbox. Can't read. Is connected on bench with extra 12v on pin 15. no ident no read Tips to read DQ500 with pcmtuner : Use permanent 12V power on pin 15, so use a battery and connect to pin 15 and GND then connect pcmtuner cables as normal … so you have power and gnd from pcmtuner AND power and ground from another 12v source. DQ500 pin 15 must be manually switched, other is permanent. most people build custom breakout to do this. Here are notes on this …. DQ500–0BT/0BH (no 0DL SUPPORT!!) to Read DQ500: only when connected directly! NOTE: the power supply must be switched manually, while only the ignition must be switched on or off (pin 15), the second contact must be connected constantly. may require 120ohm pullup on can bus built the resistor here, put between CANH and CANL pcmtuner VAG DQ500 0BT/0BH gearbox pinout
