Likely spend€4,100

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 €8,100, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Transmission

PowerShift wet dual-clutch shift faults and control module failureFord PowerShift 6DCT450 six-speed wet dual clutch€250–€2,800
Harsh or delayed shifts, a judder when pulling away or at low speed, a transmission warning, and in later stages limp mode with only some gears available. This is the Getrag six-speed wet-clutch unit, and it depends on its fluid and filter, which are usually left alone for the life of the car. Its control module and solenoids also fail, and a fault in either feels like a clutch problem from the driver's seat.
Check: Drive from cold through slow traffic and feel for judder, flare or a delayed engagement, then scan the transmission for stored faults. Ask for the fluid and filter record, since most of these have never had one.

Emissions

DPF clogging and forced regenerationDPF€250–€1,800
Warning light, limp mode, oil level rising above the maximum mark from fuel dilution. The filter needs sustained hot running to regenerate. A car used for short urban trips never completes a regeneration cycle.
Check: Read the DPF soot load and the distance since the last regeneration on a scan tool, and check the engine oil level and smell it for diesel. Ask what the car was used for. A short-trip city diesel is the wrong car regardless of mileage.

EGR cooler leakEGR cooler€400–€1,000
Coolant loss with no visible external leak, white smoke, sweet smell. The EGR cooler cracks internally and leaks coolant into the intake. BMW recalled affected diesels over a fire risk from glycol deposits igniting.
Check: Check coolant level and look for unexplained top-ups in the service history. Verify the recall was carried out. It's free and searchable by VIN.

Turbo & intake

Variable-vane turbo actuator stickingvariable-vane turbo€400–€1,200
Sudden loss of power on a hard pull, limp mode that clears on restart, underboost or overboost codes. Soot binds the variable vanes or the actuator linkage seizes.
Check: Do a full-throttle pull in third from 1,500 rpm to the limiter. Hesitation or a drop into limp mode is this fault. Do this twice.

Drivetrain

Haldex coupling pump failureC394 body€150–€1,300
Four-wheel drive that no longer engages, a warning light, or the front wheels spinning on a wet junction when the rear should be helping. The Haldex coupling depends on clean oil and a small filter, and the service is short and cheap and widely skipped. Debris then blocks the filter and the pump fails, leaving the car front-drive.
Check: Ask when the Haldex oil and filter were last changed and get the date in writing. On the test drive, pull away briskly from a standstill on a loose or wet surface and feel whether the rear takes up any drive.

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 G6DG 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.
