Common Problems & Reliability
The 2011 Volvo S80 (Gen 2) has 3 known issues. 1 of these are classified as serious faults that could be expensive to repair. 2 are moderate concerns worth inspecting before purchase.
Fuel dilution on D5 diesel - rising oil and runaway idle risk
SeriousDVSA’s recall record for the S80 of this era states plainly that oil could rise above maximum from overfilling and/or fuel dilution, letting the engine hold or increase speed after the throttle is released and, in extreme cases, run on after switch-off. Owners' Club threads on the 2.0D/D5 cars show the day-to-day version: a rough, shaking idle where the members immediately suspect a leaking injector - at roughly £300 a time. Short urban runs made it a fleet-killer; verify oil history on any diesel you test.
Symptoms: Oil level above the maximum mark with a fuel smell, Rough idle with vibration through the floor...
Est. repair cost: £150-£2,000
Sunroof and body drain water leaks into sills and footwells
ModerateThe Owners' Club has S80 owners chasing sloshing in the driver’s sill and a soaked rear footwell with no obvious entry, one discovering windscreen-edge leaks tracking into the cabin. FnF’s Volvo drain guide sets out the mechanical reason: on the S80/V70/XC70 generation the front sunroof drains exit behind the front wheels through a 90-degree elbow that clogs or slips off, while rear drains dump into the trunk area. Water in the footwell soaks wiring looms and the amplifier under the seat, turning a £50 clean-out into a four-figure electrical repair.
Symptoms: Damp carpet or a sloshing noise in the sills after rain, Musty smell or water stains under the door weather strips...
Est. repair cost: £80-£1,200
Diesel injector wear causing rough idle and high repair bills
ModerateOn the 2.0D and five-cylinder diesels, Volvo Owners' Club threads describe exactly what fleet life does to these injectors: a rough idle with vibration you can feel through the seats, and member advice to confirm which cylinder before paying around £300 a injector plus labour. The cheap first step is a proper diagnostic - leaking-back testing rather than guessing - because misdiagnosed injectors lead owners to replace pumps and sensors unnecessarily. Buy with injector test records and it stops being a worry.
Symptoms: Rough cold idle that smooths as the engine warms, Knocking or rattling at low rpm with normal oil pressure...
Est. repair cost: £350-£1,500
Buying Tips for the 2011 Volvo S80 (Gen 2)
- With a sunroof fitted, pour water through the drains at each front corner and confirm it exits under the wheels; blocked elbows dump water into the footwells and the wiring under them.
- Check the oil level for rise above maximum on diesels - fuel dilution drove DVSA recalls on these cars and its own engine-running-after-switch-off warning.
- Listen for a rough, vibration-laden idle on 2.0D/D5 cars; injectors at around £300 each are the usual suspect before anything else.
- Operate the air-suspension cars carefully - a tired compressor or leaking bellow is the expensive version of a simple comfort fault.
- 2014-on facelift cars gained standard City Safety and the bigger screen; later Drive-E engines (D4/T5 2.0) need their oil-consumption habits understood before buying.
