The most serious are gearbox (mechatronic unit failure and premature clutch pack wear in the DQ200 7-speed dry clutch) and engine (diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system issues). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.

Recall data published by the Driver and Vehicle Standards Agency under the Open Government Licence v3.0. A recall listed here may not apply to every car of this model: the build dates and the registration check are what decide it.
An overdue cambelt is the most expensive thing a seller can fail to mention on a used Polo. These are the figures UK specialists work to.
EA111 1.2 TSI 105 only: chain driven with no scheduled replacement, but the chain stretches and the tensioner fails, so listen for a loud metallic rattle on cold start. It was fitted to the Golf Mk6 and the pre-facelift Polo 6R. The EA211 1.2 TSI that took over in the Golf Mk7 from 2013 and in the facelifted Polo from late 2014 is belt driven, so a later 1.2 TSI must not be treated as having no cambelt.
VW recommends replacing the belt and tensioner every four years regardless of mileage on this engine, with kit checks every 18,000 miles. The older 1.4 16v engines are infamous for cambelt tensioner failure where the plastic pulleys shatter, so the four-year limit is the one that matters.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
Three stand out. Gearbox: mechatronic unit failure and premature clutch pack wear in the DQ200 7-speed dry clutch DSG gearbox (typically 30000 to 80000 miles). Engine: diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system issues (typically 30000 to 80000 miles). Engine: severe oil consumption due to piston ring issues, particularly in the earlier CAVD engine (typically 10000 to 60000 miles). The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
No Volkswagen Polo year is a write-off, but the Mk5 (2009 to 2017) carries the most serious faults: gearbox, engine and suspension. The Mk4 (2002 to 2009) and Mk3 (1994 to 2002) have high-severity faults on record too. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the gearbox and engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for juddering or shuddering during gear changes (especially low gears), engine cutting out or stalling at low speeds and excessive oil consumption (e.g., 1 litre every 300-1700 miles). Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 16 known faults before you travel. Check a Volkswagen Polo advert →

This list is by model, so it cannot tell you whether one particular car has had the work: the free GOV.UK MOT history check shows a recall status from the registration where the manufacturer shares it, and a franchised dealer can check the VIN.
