HI, i am new here, ive got an old audi 80 2ltr e 1992. I have a problem, where everything is ok whilst the engine is ticking over, or even reving whilst stationary, but when i pull away and drive all sorts of strange things happen, the car stereo will go on and off partially like it is not getting enough power, and the central locking will lock on its own. Also ehen the engine is off, but the ijnition is on, the battery light will flicker slightly. I have a brand new 60 amp/hour battery. Any help will be appreciated, thanks in advance. Rich.
