Hey there. I have a 2012 Jetta. I’m starting to get codes about the diesel needing to be regen. I was wondering if a tune kit would be better. Might get better fuel mileage too. I have 190000 km or like 120k miles. Got the timing belt changed at 123000km. What are my options? Love my car and would love better mileage. Can I get some suggestions?
