I'm new here, but have had my Jetta since 2011. It's a 2010 TDI 6M. Now, at about 60K miles, I decided to change the manual transmission fluid. Seeing that the VW product was about $30/liter, I did some research and found RMEuropean.com carried Fuchs Titan Sintofluid SAE 75w-80 with a product number G052-171-A2 just the same as the OEM fluid, for about $16/liter. Ordered 3, waited almost a week. The oil arrived today, but the label does not specify G052-171-A2. It does meet VW specs G 052-911-A1-A2 and VW 501 50. It is an API GL-5. So is it ok to use this product, or do I have to get the OEM GL4? I tried contacting the vendor, but they are closed Sat & Sun. It seems to me the product they should have provided for the vehicle is Fuchs Titan Sintofluid FE 75W. Any help is appreciated. Thanks in advance.
