Hi everyone. New to the forum.. just had interim service at n my T6, owned from new, and serviced at main dealer, extended warranty, 2016 model, 150k on here now, Iv just asked them when the Manual gear box oil is due for changing, and they said they don’t have it on a service schedule, and doesn’t need doing, “(I knew this). Iv changed the oil 3 times now since I’ve owned it, and it did need changing, money well spent in my eyes. All gears work as they should, no problems changing from 1st to 2nd, although it was a bit tight when I bought it at 1st. VW say it’s oil for life!! Life of what, the gearbox. The was was not good when I drained it. Only advice I could give anyone, before drain them oil, make sure you can unscrew the fill plug, as that can get corroded in. It’s a 15 minute job. Just under 3 litres of oil, and you will notice a difference when you have done it, especially for f it has never been done, and it’s done 50k or so.
