It all takes perhaps one second and nothing shows on instuments and can hapen aprox. once to ten times for 10km ride, It´s not the waveformed run as when lambda is out of order and it´s not AC compressor engaging Dont know if it is lockup that goes out and in or engine that stops and starts Lockup works as normaly . Goes in at 90 and out in perhaps 50-80 depending on footwork. All other gearchanges are so soft that I can´t feel them. Engine also runs great 1,2 to 1,3 liters / 10km No faultcodes at engine but at autotrans there is "no brake switch signal " error . This error is there even if I press brake pedal. This error has been there before this problem started. I read somwhere that brake signal is used to get lock-up out when brake is pressed and ABS i indikating that some wheel not is rotating. This could bee what happens but how to verify this and fault finding ? Bengt Post Extras
