Not every premium ages the same: when BMW looks more sensible than Audi on the used market

BMW vs Audi over 100,000 km on the used market: J.D. Power VDS data, B48/B58 with ZF 8HP, EA888 with S tronic and what to check before buying.

Past 100,000 km the BMW vs Audi argument can no longer be settled by the brand image. What matters now is the specific engine, the gearbox and how the car was serviced before being put up for sale. On average BMW looks the safer bet, but only in the lucky configurations of recent years. SPEEDME’s experts have looked into which car is the better pick.

At brand level the difference is visible in the J.D. Power Vehicle Dependability Study 2025: BMW recorded 189 problems per 100 vehicles, Audi 273. The lower the score, the better. In the more recent J.D. Power 2026 ranking BMW again sits noticeably above Audi, although the exact scores for every brand aren’t published in plain text. The premium segment today often suffers not from engines breaking down, but from electronics, infotainment and software — and after 100,000 km even a single ECU fault can cost unpleasantly much.

BMW offers the calmest scenario on the used market — the petrol B48 and B58 paired with the classic ZF 8HP automatic. The B48 went into mass production in 2016 and is considered one of the more successful modern engines from the brand. The B58 is more powerful and more enjoyable, but servicing the six-cylinder version is more expensive: injectors, oil, cooling and road tax quickly remind you this is no longer a «cheap entry» into premium. On the upside, the market has long since mapped the weak points of these engines, and the repair strategy doesn’t look like a lottery.

With Audi the picture is less straightforward. Modern TFSI and S tronic units have become tougher than their early reputation from a decade ago suggested, and the diesel versions, with healthy fuel equipment, can be very successful. A lot depends on the EA888 generation, the condition of the S tronic, the type of all-wheel drive and the service history. Late 2.0 TFSI engines are noticeably better than the early problematic ones, but past 100,000 km oil intervals, chain condition, turbo, mechatronics and clutches all matter. On older cars, issues with modules, electronics and gearboxes show up more often, and on crossovers like the Q5, after 100,000–130,000 km, you also get squeaks, suspension and expensive diagnostics.

Practical choice: a well-serviced BMW with B48/B58 and ZF 8HP usually looks more predictable than an Audi with an unknown S tronic history. But a good Audi with transparent service will be better than a BMW after overheating events, infrequent oil changes and cheap repairs.

Before buying anything past 100,000 km, the most important thing is to check more than just the service book: error codes per module, gearbox condition, cooling, leaks, oil change history and the actual usage pattern. The closest thing to a safe benchmark isn’t the badge on the bonnet, it’s the combination of «engine plus gearbox plus servicing». BMW currently has slightly more lucky combinations of that kind.
