Hello! in 1995 stored trouble codes used the On Board Diagnostic I software (OBDI)..Scanners will not work...The control unit LED can indicate any number of simultaneous component conditions by blinking separate codes, one after another...An instrument panel mounted indicator lamp will light and stay lit. If the lamp is on, or if a system malfunction is suspected even though the lamp is off, it is necessary to inspect the electronic control unit LED display. The LED display is on the ECM (ECU), which is located just below the RH side of the instrument panel. The indicator lamps operate whenever the ignition is On and a DTC is stored in the ECM (ECU) memory.
When an abnormality is detected the ECM (ECU) display blinks. The LED blinks a certain number of times, with the number of blinks indicating the number of the DTC. After the LED blinks a number of times there will be a two second pause and the LED will blink out the number of the next DTC..here are the codes..If there is a code send it to me...If there isn't a code I'll take it from there...guru.saailer

went out to work on my car to debadge it. had to put it in neutral and roll it forward to get to the back of the car. Anyway I also did a throttle body adjustment I read on the internet, by turning on the key just before it starts, pushing on the gas pedal to the floor turn off key, wait 5 seconds and release gas pedal. I went to start my a4 and it just cranks. starting checking the fuses and found #29 ECM 20amp fuse blown. I tried swapping another from close to it and it blew immediately. Any help would be appreciatted. Brent.
