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 €3,700, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Engine

Timing chain stretch and tensioner wearPrince timing chain€1,100–€1,900
A rattle from the front of the engine for the first seconds after a cold start, and later a rough idle or a fault code for camshaft timing. The chain and its tensioner on the BMW and PSA Prince family stretch with age and heat cycles rather than with distance. Once the chain is slack it can skip a tooth, and that damages valves.
Check: Start the car from stone cold and listen carefully through the first five seconds. Any rattle means the work is due, so ask for a receipt rather than accepting an assurance.

Turbo & intake

Carbon buildup on intake valvesdirect injection€400–€700
Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.
Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.

Suspension

Electric power steering pump failureR56 body€450–€1,100
Steering that goes heavy without warning, a warning light, and a cooling fan for the pump that runs constantly. The pump sits low at the front of the car where it takes water and road salt, and its electronics fail. A blocked or dead cooling fan brings the failure forward, which is why the fan is worth checking on its own.
Check: Turn the wheel lock to lock while stationary and feel for any heaviness or hesitation. Listen for the pump fan running at idle, since a fan that never stops is a pump working too hard.

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 N14 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.
