  • '91 Coupe quattro 7A - tach and trip computer intermittent

    Hi everyone,

    As much as I love this car, it does demand attention! The latest nuisance from my 7A Coupe quattro is an intermittent tachometer and trip computer that together do not turn on when I start the car and then just come alive at a random time as I am driving.

    Tachometer and trip computer always go off and on at the same time.

    Any thoughts? Thank you in advance.

    Sounds like it could be caused by a bad connection or failing power/earth connection/rail on the cluster PCB. Gotta hate intermittent faults - will be dead easy to find when it's failed
