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 €4,950, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Fuel

High-pressure fuel-pump cam follower wear (S3)BHZ/CDLA 2.0 TFSI (S3)€40–€2,000
Low fuel-pressure limp mode, hesitation and an EPC light; if the follower wears through it wrecks the pump and scores the camshaft. The bucket follower between the intake camshaft and the high-pressure fuel-pump plunger wears and can perforate. It's a service item that's often overlooked on hard-driven cars.
Check: The follower is behind two bolts. A specialist can pull the pump and inspect it in minutes. Ask when it was last changed.

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.

Transmission

DQ250 wet-clutch DSG mechatronic and service neglectVW group DQ250 six-speed wet-clutch DSG€700–€1,500
Jerky or harsh shifts, clutch flare or judder, an occasional drop to neutral or limp mode, and gearbox fault codes. Mechatronic valve-body and pressure-accumulator faults, aggravated by a missed 60,000 km oil-and-filter service. The wet six-speed is the more durable of the DSGs but not maintenance-free.
Check: Confirm the DSG oil-and-filter history, test-drive for harsh or flaring shifts at low speed and under load, and scan for gearbox faults.

Suspension

Rear multi-link bush and drop-link wearA3 platform€200–€500
A knock or clunk from the rear over bumps and potholes, vague handling, and uneven rear tyre wear. The rear multi-link control-arm bushes and drop links wear, often several together, so the noise is worth diagnosing before replacing parts. Age and mileage both drive it.
Check: Drive over rough surfaces listening for a rear clunk; on a ramp, lever each rear arm bush and drop link for play.
SuspensioncommonPartly detectableevidence: documented100–200k km

Interior

Instrument-cluster (FIS) pixel failureA3 platform€120–€250
Missing pixels, lines or columns on the central driver-information display, often worse when the car is warm. The cluster's LCD and its ribbon and solder joints degrade with age. It's a nuisance rather than a safety fault, though a full cluster failure is possible.
Check: Cycle through all the trip and service menus checking every segment, both cold and after the car has warmed up.

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 CDLA 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.
