2013 Volvo S80 2.0L Diesel · SD63 XMG

DVSA’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.

The 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.

On 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.
