Likely spend is the mid cost of every issue rated common or universal, added together, what an unmaintained example owes over the next few years, not a prediction for any one car. Worst case if everything here failed at once is €1,950, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Transmission

DQ250 wet-clutch DSG mechatronic and service neglectVW group DQ250 six-speed wet-clutch DSG€700–€1,500
Jerky or harsh shifts, clutch flare or judder, an occasional drop to neutral or limp mode, and gearbox fault codes. Mechatronic valve-body and pressure-accumulator faults, aggravated by a missed 60,000 km oil-and-filter service. The wet six-speed is the more durable of the DSGs but not maintenance-free.
Check: Confirm the DSG oil-and-filter history, test-drive for harsh or flaring shifts at low speed and under load, and scan for gearbox faults.
TransmissionoccasionalPartly detectableevidence: documented80–160k km

Electrical

Pump-duse injector loom chafingBKC 1.9 TDI PD€150–€450
Misfire, rough running, intermittent injector codes that move between cylinders. The wiring loom to the pump-duse injectors runs under the rocker cover and chafes with age and heat.
Check: Scan for injector codes; intermittent faults that wander between cylinders point at the loom rather than the injectors.

How to read this

Every issue is authored once against the part that actually carries it: the engine, the gearbox, the chassis or a shared component, and inherited by every variant that has that part. The badge next to each issue says where it comes from, so you can tell an BKC problem from an E9x problem.

Evidence tiers. Manufacturer means a recall, technical bulletin or revised part number. Documented means workshop data or multiple independent sources. Reported means owner consensus with no hard confirmation, and never sets a risk level on its own.
