    One of the trickiest lights is the ‘Check Engine Light’

    The fix is not always easy. If you check with a Scanner things might get even more complicated. For Audi Sedans such as A4, the general rule is try and not drive the car if the Check Engine light appears.. as many deem it to be dangerous.

    Some people go as far as saying that it is better to get the car towed to a dealership than to drive it. I won’t go as far as that, but is always a cause of concern.

    The most common issue can be an Engine misfire, which can be bad for the engine if not fixed quickly.
