My Blue one (6 speed TT 1993 facelift 4WS, 4WD) has had ECS light flashing since I bought it years ago . Happy with whichever setting its stuck in .
Now have ABS light on so have been sorting out plug in diagnostics to sort out the two problem sources and the iffy active aero circuit.
However just back from garage electrical/tuning problem solving guys and they cant get a reading from the socket with OBD1 plug.(drivers side inside floor)
Taking it back next week but has anyone had this problem and sorted cause ,to help reduce the bill or enable me to get a bit that’s needed
