We bought a new/used 2017 Jetta Mk 6.5 Jetta GLI and need to repair an oil leak and assess the overall condition. I also decide to service the DSG transmission because we don't know the service history.
Here are some links that might help.

The timing chain cover parts were purchased from ECS Tuning. Check their website for parts availability and fitment. I have no affiliation.

As an Amazon Affiliate I receive a small commission if you purchase parts using these links. There is no cost to you.

Thanks for watching!
