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 €5,800, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Engine

Timing chain tensioner failure (1.2 TSI)CBZB 1.2 TSI€650–€1,400
A rattle in the first seconds after a cold start, then a misfire or a no-start once the chain has jumped a tooth. The original tensioner can release its tension when the engine is stopped, which lets the chain go slack. On restart the chain can skip, and on this engine that bends valves. Volkswagen supplied an updated tensioner, so which part is fitted decides the risk.
Check: Start from stone cold and listen through the first five seconds, then ask whether the updated tensioner has been fitted and get it in writing. Treat an early car with no paperwork as carrying an engine bill.
Later parts: Updated chain tensioner fitted from later production and available as a retrofit

Transmission

Dry-clutch DSG mechatronic failureVW group DQ200 seven-speed dry-clutch DSG€1,200–€2,800
Juddering at low speed, harsh or refused engagement, warning lights, or a car that won't select a gear. The seven-speed dry-clutch unit's mechatronic and clutch packs wear, and the clutches are far less tolerant of stop-start use than the wet-clutch six-speed.
Check: Drive from cold in traffic. Judder pulling away, hesitation between first and second, or a jolt on the overrun are all this. Ask for the service history. These need fluid and clutch adaptation work.

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.

Electrical

Water ingress into the footwellsFabia platform€120–€900
Damp carpets on one or both sides, misted windows that won't clear, and electrical faults that come and go with the weather. The plenum drains under the windscreen scuttle block with leaves and debris, and the water then finds its way past the bulkhead seals. Once it reaches the wiring and control units under the carpet the faults look far more serious than the cause.
Check: Lift the carpets in both footwells and press down hard with your hand, then smell the cabin. Damp underlay on a dry day tells you the drains have been blocked for a while.

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 CBZB 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.
