Things you need to know about CVT gearbox
CVT gearbox is a type of automatic transmission that can be found in many cars. It is more efficient than the traditional manual or semi-automatic transmissions because the CVT gearbox transmits power transversely.
A CVT gearbox has a ratio that is variable, with infinite variations of transmission ratios. This allows the vehicle to have an optimum setup for all driving conditions.
CVT transmissions are also more fuel-efficient than other types of automatic transmissions because they can reduce engine power while maintaining speed and torque, which conserves fuel.
Things you need to know about CVT gearbox
- Very demanding on the quality of the transmission fluid, and at Melbourne Euro we only use G 052 516 A2. A complete replacement will require 7 liters of transmission fluid.
- Renew the oil and the corresponding filters every 60 thousand km, and when it is older, you should do it more often.
- At the same time, you should also take care of replacing the oil line.
- The driver must follow the driving style. Variator categorically does not tolerate sudden acceleration, braking.
- Noticing the first sign of a malfunction, you should contact Melbourne Euro for an advice, the pull chain and pulleys get worse, once chain is broken into pieces it's a big job to repair.
At Melbourne Euro, we offer full CVT services in Melbourne, from diagnose, supply, repair and more.
A Direct Shift Gearbox, or DSG for short, is a gearbox that can change gears without the need for a clutch. DSG are the most common type of transmission in modern cars.
However, they don't come without any problems. Here are the most common ones:
- The 7-speed DQ200 and 6-speed DQ250 gearboxes sometimes suffer from power loss (gear disengaging) due to short-circuiting of wires caused by a build-up of sulphur in the transmission oil.
- Jerky, hesitant operation, Jumping, thumping is one of the most common complaints drivers have with their dual-clutch transmissions. Such hesitation is usually felt when pulling away from a stop or while traveling at low speeds and coming to a full stop at the traffic lights.
- Error message on dashboard: (Gearbox Malfunction, You Can Continue Driving.)
- Mechatronic failure
- P17BF - Hydraulic pump system overload protection
- 06079 - Hydraulic pump, play protection
- 06300 - Function restriction, due to insufficient pressure build up
- 06293 - Function restriction due to pressure drop
- Shaking / juddering in 1st gear and when changing into higher gears
- Current gear flashes on dashboard
- Flashing engine management light or P R N D S on dashboard
- P2711 unexpected mechanical gear disengagement
- Clutch slip or banging on engagement
- Fault code 06293 function restriction due to pressure drop
- Fault code 01851 stuck in gear 6
- Software Adaptation failures
- Adaptation Drive not completed.
- Basic Settings not done properly.
- Clutch Calibration not completed properly.
- Wet clutch failure
- Clutch 1 or Clutch 2 P17CF Slippage too High
- Sensor, Solenoid and TCU Problems:
- P179E Drive Position Sensor Electrical Error.
- P179F Drive Position Sensor Malfunction.
- P060A - Internal Control Module Monitoring Processor Performance.
The good news is at Melbourne Euro, we are capable of fixing any problems with DSG. You can always contact us.

Common problems with CVT Audi 0AW Transmission
The enhancements made in the 0AW transmission model significantly increase the life of the unit in comparison with the older 01J counterpart. However, this isn't flawless. The problems that arise, unfortunately, are still very similar:
- Failures of the TCU (transmission electronic control unit)
- Mechatronics in general, chains, and pulleys.
- Any rebuild 0AW (VL381) involves the mandatory replacement of all consumables: gaskets, solenoids, filters, seals, ejection pump.
The good news is at Melbourne Euro, we are capable of fixing this, should you ever encounter a problem with your Audi transmission.
Features of the transmission CVT 0AW (VL381)
Learn about the main features of CVT 0AW transmission (VL381) for Audi.
- Stepless variator with a pull chain.
- Designed for vehicles with longitudinally positioned gasoline engines with a volume of 1.8 to 3.2 liters.
- Creates a torque of up to 400 Nm. Corresponds to an 8-speed gearbox.
- This number of gears provides the so-called «sports mode» of driving. In this case, the load is not the entire surface of the pulleys, but only the central part of them. The transmission of torque becomes intermittent. «Sports» riding significantly reduces the resource of the mechanism. During the normal driving mode, the surfaces of the pulleys are fully engaged.
