The essentials.

3 documented, sourced faults across its 4 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 engines with the fewest documented faults are: 1.6 / 2.0 (atmosférico) (Petrol), 2.5 TDI V6 (Diesel).

Which engine has the fewest documented faults?

Documented faults and recalls by engine for the Volkswagen Passat B5 / B5.5
Engine	Documented faults	Recalls
1.6 / 2.0 (atmosférico)PetrolFewest documented	11 with conditions	1
1.8 TPetrol	22 with conditions	1
1.9 TDIDiesel	21 with conditions	0
2.5 TDI V6DieselFewest documented	11 with conditions	1

According to the data we have, the engines with the fewest documented faults are: 1.6 / 2.0 (atmosférico) (Petrol), 2.5 TDI V6 (Diesel).

By fuel, all versions have the same number of documented faults.

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.

Airbag inflator deterioration due to moisturePassive safety

Engines: 1.6 / 2.0 (atmosférico) (Petrol) · 1.8 T (Petrol) · 2.5 TDI V6 (Diesel)

How to check it: Check VIN; replace the inflator or module specified by the recall.

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 3 checked

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.

Known weak points

Water in the brake servo and engine from blocked drains (Passat B5)
Look out for: Water building up below the windscreen (ventilation plenum) that rusts the brake servo from inside: a hard brake pedal, less braking or failure; if the diaphragm perforates, the engine sucks in water (emulsion under the oil cap) and can hydrolock. Also damp carpets from blocked air-conditioning or sunroof drains.
Ask them to check: Clear the drains below the windscreen; look for water there and emulsion under the oil cap; feel the carpets.

Engine

Ignition coils on the 20-valve 1.8 T
Look out for: Misfires, hesitation and the engine light; the engine runs on one cylinder fewer.
Ask them to check: Read the per-cylinder misfire codes and replace the affected coil (preferably with a revised one).
