VW G 055 540

Specification VW G 055 540 is the Volkswagen Group requirement for synthetic transmission oils intended for automatic gearboxes, including DSG, DQ‑series and other multi‑speed automatic transmissions installed in passenger and commercial models of VW, Audi, SEAT and Škoda. Oil that meets this standard must have low viscosity on cold start, high thermal resistance and stable friction properties, providing smooth gear shifts, protection of gear teeth and preventing overheating of torque‑transfer elements. Technical requirements include control of torque loss, stability across a wide temperature range (‑40 °C to +120 °C), low oxidation tendency and the absence of aggressive additives that could damage electronic sensors and transmission control valves. The specification does not impose special requirements for SAPS, DPF or catalysts, as it concerns only the transmission system, however the oil is fully compatible with emission control systems used in these powertrains. In the XENUM catalogue you will find several synthetic products marked VW G 055 540, such as X1 0W30, X1 5W30, PRO‑LL 0W30 and PRO‑LL 5W30, which provide the recommended quality and can be used as a replacement for the original VW‑fluid without compromising warranty requirements.
