    The current A4 incarnation, the B8, could potentially share the newest Volkswagen MLB platform with one of the vehicles to be introduced by its sister company, Porsche.

    Like the last Audi 80 model that hit the shelves in the mid 90s, a high performance version of the Audi A4 was also made available.

  • Common Problems with the Audi A4

    One of Audi's best-known vehicles is the A4, a compact executive car that was first introduced back in 1994 and is still being produced today. Often credited as one of Audi's most commercially successful vehicles, the A4 has long been a popular choice for those who are after a compact luxury car at a more affordable price range. Even though it's well received by drivers and critics alike, this vehicle has its share of common problems that have affected owners over the years. Recognizing these issues beforehand is important so that motorists can have these problems fixed or replaced with Audi A4 parts before they end up ruining their precious ride.

    Gearbox issues

    Most Audi owners have reported numerous problems with the A4's automatic gearbox, and most of these issues revolve around the car's Electronic Control Unit or ECU. This component controls the movement of the transmission system whenever a driver selects gears. A warning light will usually flash on the vehicle's dashboard whenever there's a problem with the ECU. Should the ECU fail entirely, the vehicle will lose power, the driver can't shift to reverse, and the car won't even move when shifting to drive. Unfortunately, Audi hasn't issued a recall or explanation for the A4's ECU problems.

    On a lesser note, some owners have reported that the A4's gearbox tends to slip. Once the gearbox begins to slip, the vehicle would suddenly jerk or hesitate whenever it's accelerating. Most owners agree that this issue can often be traced back to low transmission fluid, worn internal gears, or even improper gear adjustment. It's best to have the gearbox checked ASAP before any major problem further damages the gearbox.

    High oil consumption

    It seems that some A4 models are also experiencing higher than normal oil consumption, especially when they are in stop-and-go traffic. It is a common problem with the 2009 - 2011 Audi A4 and is often traced to a faulty crankcase pressure-regulating valve. Owners who notice a sudden increase in oil consumption from their Audi A4 should have this valve checked to see if it needs to be replaced immediately. Do note that the front crankshaft seal must also be replaced whenever this valve is removed.
