Audi A6 transmission oil is the dedicated CVT transmission oil for Audi, with the model number LGA052180A2. The Audi A6 CVT transmission oil is generally recommended to be replaced every 2 years or approximately 40,000 kilometers. Different models have different replacement cycles. Below are the replacement cycles for transmission oil: Manual transmission: Manual transmission oil is generally recommended to be replaced every 3 years or approximately 100,000 kilometers. Automatic transmission: Automatic transmission oil is generally recommended to be replaced every 2 years or approximately 40,000 kilometers. Continuously variable transmission (CVT): CVT transmission oil is generally recommended to be replaced every 2 years or approximately 60,000 kilometers. The methods for replacing transmission oil are as follows: Unscrew the drain plug at the bottom of the transmission to drain the oil before refilling. Remove the transmission oil pan directly to drain and refill the oil: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission oil: A smart circulation machine can dynamically replace the oil, filtering and cleaning sludge and impurities inside the automatic transmission.

My old A6 had me confused when changing the transmission fluid last year. The model depends on which transmission you have—for example, the CVT Multitronic requires fluid with G055162A2 certification, while the dual-clutch DL382 needs G055532A2. There was a label on my car's oil pan marked G055005, which I later found out was an outdated standard. At the auto repair shop, I specifically checked the fluid color: reddish-brown means it's probably time for a change, while pitch black is definitely overdue. If you're buying online yourself, make sure the bottle has the Volkswagen Group TL52146 certification mark. I've seen people cheap out and buy off-brand fluid, only to end up with a transmission that jerks like riding a horse.

Just checked this for my neighbor's A6L last week. Getting straight to the point: Look for the vehicle data sticker under the spare tire compartment in the trunk - the transmission code on it is crucial. Most commonly, the 0B5 transmission requires genuine G052516A2 fluid, or you can opt for the rebranded ZF LG8 variant. During maintenance, don't fall for bottle additives - Audi's ZF transmissions are particularly sensitive to chemical additives. Practical tip: Unlike engine oil, this fluid doesn't need frequent changes (replace at 80,000km intervals) but must be OEM. Once saw aftermarket fluid swell seals causing leaks.

A friend in auto parts taught me how to choose oil by model year. For all A6 models after 2016 with the 0CK transmission, the oil must be G055162A2 with a viscosity of 7.6cSt. Older models with the 0B5 transmission require G055005 in the blue bottle. The most easily overlooked are the quattro versions—the multi-plate clutch demands oil marked with DCTF. Key reminder: Only ZF replacement oils with the Audi four-ring logo at the bottom are genuine. During oil changes, the mechanic must reset the adaptation values with a diagnostic tool first, or the jerking will make you question your life choices.
