Likely spend€5,650

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

Engine

Timing chain tensioner failureEA888 chain tensioner€900–€1,800
Rattle for a second or two on cold start, chain noise from the back of the engine, timing correlation faults, or no start after the car has stood. The early hydraulic tensioner can lose tension and allow the chain to jump. The chain is at the gearbox end of the engine, so access is poor and a failure usually bends valves.
Check: Insist on a stone-cold start and stand at the bulkhead end of the engine. Any rattle beyond the first half-second is this until proven otherwise. Ask for a tensioner receipt with the part number. The revised part is the fix, not the mileage.
Later parts: Revised tensioner part number; fitted from later production

Timing chain and tensioner wear (1.4 TSI)CAXA 1.4 TSI€700–€1,600
Rattle on start-up, chain noise that grows, timing correlation codes, and in the worst case a jumped chain and bent valves. The EA111 1.4 TSI uses a short chain with a tensioner that can lose tension and allow the chain to skip. VW revised the tensioner.
Check: Cold start and listen at the timing end. Any rattle beyond the first moment is this. Ask for a tensioner receipt with the revised part number.
Later parts: Revised tensioner part number on later production

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

Plenum drain blockage and module water damagePassat platform€0–€1,200
Damp or soaked carpets, misted windows, and electrical faults that come and go as water reaches the control modules under the seats and in the footwells. The drains in the plenum chamber under the windscreen block with leaves and debris, and water then overflows into the cabin. The comfort control module sits low enough to be soaked, which is where a cheap fault turns expensive.
Check: Lift the carpets front and rear and press for damp, check under the seats for corroded module connectors, and clear the plenum drains yourself before you buy.

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 CAXA 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.
