The essentials.

4 documented, sourced faults across its 3 engines.
2 of them depend on the equipment or the production date: ask what this car has.
1 official recall on record: ask for the chassis number (VIN) and confirm it has been done.
According to the data we have, the engine with the fewest documented faults is the 1.6 FSI (Petrol).

Typical faults by engine

According to the data we have, the engine with the fewest documented faults is the 1.6 FSI (Petrol).

By fuel type, the one with the fewest documented faults is: Petrol.

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
Ask an official Volkswagen dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

On the test drive: what to look and listen for

Taken from each sheet's symptoms and checks. You can tick off what you have already looked at: it is saved only in this browser.

0 of 4 checked

Timing system

EA111 TSI chain and tensioner
Look out for: Rattle on a cold start, engine light for timing deviation; if the chain jumps, the engine cranks but won't start.
Ask them to check: Listen to a cold start and read the timing deviation values with VCDS. Ask for an invoice showing the revised kit was fitted.

Injection / cylinder head

PD TDI camshaft, injectors and cylinder head
Look out for: Growing noise from the cylinder head, power loss and rough running (cams and lifters); unstable idle, smoke or hesitation (injectors); on the 16-valve 2.0 TDI, coolant loss with no visible leak from a cracked head.
Ask them to check: Check the oil history (VW 505.01), listen to the head, check injector balance rates with a diagnostic tool and, on the 16-valve 2.0 TDI, read the head part number (03G 103 351) and look for coolant loss.

Climate control

A/C not cooling: N280 valve
Look out for: The air does not cool or cools intermittently (for example only at motorway speed), and sometimes the compressor rattles with the A/C on. Codes 01232 (N280 valve), P2612 or 00898.
Ask them to check: Read the codes and N280 control current with VCDS or ODIS, measure its resistance (about 10 ohms) and check the connector and wiring before replacing parts. If the valve or compressor is replaced, the whole circuit must be flushed.

DSG gearbox

DQ250 DSG mechatronic and oil
Look out for: Jerking or shudder when pulling away and at low speed, harsh shifts, gearbox warning or limp mode; codes P17BF, P189C, P0841, P0871 or P0717.
Ask them to check: Read codes with ODIS or VCDS, check the oil change history, inspect the pan for rust or leaks and the clutch adaptation values. Replacing the mechatronic control board is often enough.

OBD codes worth looking for

If they let you read the fault memory with an OBD reader, these are the codes mentioned in this model's sheets:

P0016 01232 P2612 00898 P17BF P189C P0841 P0871 P0717
