I (23M) bought a 2018 Skoda Octavia 4x4 (DSG7 DQ381) from a dealer last December. The seller advertised it as "in great condition" with full service history, and I paid $15,000. I asked specific questions about maintenance before buying, and they assured me everything was fine. Fast forward to now: I just discovered the DSG transmission oil was never changed—not once in 87,000 miles (139,500 km). The only Haldex oil change was at 46,500 miles (74,942 km) in 2021, and it’s now overdue by 21,000 miles (35,000 km). The seller never mentioned this, and the service records they provided were incomplete. I’m changing both oils next week and sending samples for analysis. If the results show serious damage, I’m considering voiding the purchase under consumer protection laws. The seller hasn’t responded to my messages yet.

AITA for wanting to void the sale over this? I feel misled, but I also wonder if I should’ve caught this myself.

Hey everyone,

I’m in Norway and recently bought a 2018 Skoda Octavia Combi 4x4 (2.0 TDI, 150 hp, DSG7 DQ381) with 139,500 km (~87,000 miles). The seller claimed it was fully serviced, but I just found out no DSG oil changes are documented - ever.

I’ve heard conflicting info about the official interval:
• Some say 60,000 km (37,000 miles).
• Others claim Skoda’s official recommendation is 120,000 km (75,000 miles).

Does anyone know Skoda’s official interval for the DQ381?
• Is it truly "fill-for-life," or is that a myth?
• How critical is this? Could running it unserved for 139,500 km / 87,000 miles cause major damage?

I’m changing both the DSG and Haldex oil next week and will send samples from both for analysis. The only documented Haldex oil change was at 74,942 km in 2021, so it’s also overdue.

Any owners with experience or advice? Trying to avoid a costly mistake! Depending on the analysis results, I might consider voiding the purchase.
