no response from controller
I am in need of help for an FTDI Chip FT232RL can't get it to work with Vag-com. Always get "no response from controller" message
What Ive done so far:
tryied installing FTDI's latest drivers v.2.04.26 for VCP (also tryied D2XX but didn't work as well)
When deleting drivers I use their removal software provided by FTDI FTCLEAN
COM ports and me are like old friends so the problem is not here ( Ive tryied every single com ports with every possible Baud Rate combinations, tryied to lower received byte rates,lowered 16ms to 3ms ...
Tryied every single ross-tech software versions (except the newest one) for Modern Serial, Twin-USB 409.1 and 311.2N
Tryied to "force dump mode"
Changed Starting Baud in software
of course inbetween every software changes Ive turn the key on and off in the car
The LED does come green when plugged in OBD-2 socket
Went through K-Line bugs one at the time, Measured voltage between pin 4 and 7 to make sure there was no K-Line bugs (voltage was lower than 9volts like expected when K-Line is setup correctly)
Car is : ECU is AudiTT 180HP 2001
Aftermarket Alpha-Bid FT232RL Chip Ebay cable compatible with ross-tech
Anyone can add something here?
Thanks
