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 €3,750, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

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.
EmissionscommonPartly detectableevidence: documented120–250k km
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.

Suspension

Rear suspension and tailgate wearJ10 body€200–€600
Knocking from the rear over bumps, uneven rear tyre wear, and a tailgate that no longer holds itself up. These carried families and luggage for their whole lives, so the rear bushes and the tailgate struts wear. Ordinary use rather than a design fault, but it turns up on almost every high-mileage example.
Check: On a ramp, lever the rear bushes for play and check the tailgate holds itself open. Look at the inside edges of the rear tyres.

Transmission

CVT fluid degradationToyota Multidrive S CVT€200–€350
A gradual change in how the gearbox holds revs, occasional shunting at low speed, and in neglected cases juddering under load. Toyota specifies the fluid as a lifetime fill. Specialists widely disagree, and a change at around 100,000 km is inexpensive insurance against a gearbox that's otherwise proved dependable.
Check: There's little to see at a viewing, so ask whether the fluid has ever been changed and budget for it if the answer is no.

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 M9R 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.
