Hello all, this is my first post. I have been looking at this forum for years, but never registered. I am need of an educated opinion. This looks like it is the place to get it. I recently purchased a used 2014 vw tdi jetta sportwagon. I did not know the history at first, but now I do. My mistake, but that is water over the dam. The original oil in it was changed at 30000 miles at the vw shop. I purchased the car with 50000 miles on it. I could not locate a oil filter for it, except at vw, so I took it to an independent vw shop, had the tranny fluid changed and the oil with motul 5/30 507 504. So this time it had 20000 on it. The tranny change interval I am ok with, Original filter in tranny. I ordered a fuel filter and changed that myself. Original fuel filter in it, so 50000 miles on fuel filter. The car came from carlbad ca,. In az I dont usually get water in my other diesels. The 2014 does not have a water drain on the fuel filter, as I guess the filter does it all, provided it is changed.... The part that concerns the most is the 30000 oil. The car runs great. It bothers me though. My option from here, as I see it, are to sell the car and buy another, monitor the oil consumption over the next 5000 miles, maybe try to put some kind if cleaner like see foam in it. The bottom of oil cap look clean no gunk, can not see much else. Any opinions or facts on how to tackle this, as I really like these cars? I think that shortly after the owner purchased it, july 2014, the scandal hit, and the owner let it go back in 2017 and did not care about the maintenance. That's 50000 in 3 years. I see some vw in europe go 30000 mile on oil change under ideal conditions. Thanks
