2022 Peugeot 308 Allure Prem SW S/S Phev A 1.6L Hybrid electric · LL22 ADO

As a plug-in hybrid, this 308 SW officially returns around 235 MPG on the WLTP combined cycle, but real-world figures depend heavily on how often the battery is charged — petrol-only running typically delivers 45-55 MPG. The 1.6-litre PHEV powertrain falls into insurance group 27-28 depending on trim, which is moderate for a family estate of this size. Road tax is currently £170 per year for the PHEV variant, though this is set to rise for hybrids in future years; company car users benefit from a low 8% BIK rate, which is a key reason these models are often found in nearly-new fleets.

Routine maintenance is similar in cost to a conventional 1.6 PureTech petrol, with annual services typically costing £200-£300 at an independent garage or £350-£500 at a Peugeot main dealer. The hybrid system adds some long-term considerations: the 12.8 kWh battery is covered for 8 years / 100,000 miles, but eventual replacement could run into four figures, and the charging cable and onboard charger components can also be expensive. Including fuel (assuming moderate charging discipline), tax, insurance, and servicing, a realistic annual running cost is roughly £2,200-£2,800, with electricity costs heavily dependent on home charging setup.

Begin with the specific defect recorded in the MOT history: a wiper blade failing to clear the windscreen effectively. Confirm the wipers now clear cleanly across the full sweep, and inspect the wiper linkage and motor for any stiffness or noise, as the wiper assembly is mounted in an area known for collecting debris on this model. The scuttle panel and bonnet drainage channels should also be checked for blockage, which can cause water ingress into the cabin and the front electrics.

For a PHEV of this age, pay particular attention to the charging port (look for corrosion or damage around the pins), the type 2 cable for any cuts or exposed wiring, and the charging flap mechanism. A diagnostic check of the hybrid system should confirm the battery state of health and whether the car can drive in electric-only mode over a reasonable distance — anything significantly under 20-25 miles of real-world EV range suggests battery degradation. Also inspect the rear floor area and boot of the SW estate for any water staining, as the 308 SW has been known for tailgate seal issues, and check the 16-valve 1.6 PureTech engine for timing belt service evidence, as this engine family has had well-publicised timing belt concerns in earlier applications.

General inspection should cover the standard i-Cockpit digital instrument panel for pixel faults, the 10-inch infotainment for software glitches, the operation of all switchgear, and a thorough test of the regenerative braking and transition between electric and petrol propulsion under load.
