Common Volvo S60 Problems & the Parts That Fix Them

• Whistling or hissing from the engine bay — stops when you remove the oil filler cap (definitive test)
• Rough idle or uneven engine note
• Oil dipstick pushed up or blowing out — crankcase over-pressure
• Unexplained oil consumption with no visible external leak
• Oil leaks from camshaft and crankshaft seals
• Smoke from exhaust and turbo noise in severe cases

Affected years: 2001–2009 Gen1 S60 (B5244T, B5254T, B5254T2 five-cylinder engines); some 2010–2014 Gen2 five-cyl also affected. Most common after 120,000 km.

The PCV breather box — a plastic unit below the intake manifold — collects oil vapour mist and traps the residue. Over time, carbon deposits and oil sludge clog the box and the brittle connecting hoses, preventing crankcase gases from venting. The excess pressure pushes past gaskets and seals throughout the engine. FCP Euro's S60 PCV guide confirms that infrequent oil changes accelerate clogging significantly. The Matthews Volvo Site documents the full repair procedure including the intake manifold removal required.

Replace the entire breather box and hose kit — patch repairs don't last on aged plastic. Most independent S60 workshops quote 4–6 hours for the job; parts kit runs R800–R1,800. DIY difficulty: Hard — intake manifold removal required.

• No symptoms before catastrophic failure — the belt snaps without warning
• Engine suddenly dies while driving and will not restart
• Loud metallic bang or clatter on failure
• After failure: bent valves, damaged pistons (interference engine)
• On Drive-E D4/T4/T5: rough running or misfires if belt is already stretching

Affected years: Gen1 S60 (2001–2009) all five-cylinder petrol/turbo; Gen2 S60 with Drive-E 2.0L engines (T3/T4/T5/D4, approx 2015–2018). Six-cylinder B6 engines use a chain and are not affected.

Rubber belts degrade from heat cycles and age regardless of mileage. Volvo's official interval for the Drive-E 2.0-litre is 150,000 miles (approximately 240,000 km) or 10 years — but independent Volvo technicians consistently recommend 100,000–120,000 km in practice. Go-Parts' S60 timing belt guide covers the belt-vs-chain breakdown by year and engine. The Volvo Owners Club UK forum is emphatic: never skip this service on an interference motor. Always replace the tensioner, idler pulleys and water pump at the same time — labour is the expensive part.

Replace the timing belt kit on schedule — belt, tensioner, idler pulleys and water pump together. Never let a second-hand S60 purchase proceed without confirming belt history. DIY difficulty: Moderate-Hard — requires timing tools and significant engine access.

• Oil level drops 1–2 litres between services with no visible external leak
• Blue or grey smoke from exhaust, especially on acceleration
• Oil smell from the engine bay
• Spark plug fouling — black, oily deposits
• Loss of power over time as cylinders load up with carbon
• Check engine light with misfire codes

Affected years: 2013–2016 S60 with 2.0L Drive-E four-cylinder and 2.5L five-cylinder (T5, T6 petrol variants).

A US class action lawsuit (Buchanan v. Volvo Car USA) documented that these engines contain defective piston oil-control rings that cannot clear oil from the cylinder walls on the downstroke. Oil accumulates on the piston crown, enters the combustion chamber and burns. CarComplaints.com reported on the class action, with owners facing repair bills exceeding $10,000 USD at dealer rates. Top Class Actions documented the full complaint, which reached a private settlement in May 2023. Volvo revised the piston ring design from 2016 with larger oil-drain holes as a countermeasure.

If the car burns more than roughly 0.5 litres per 1,000 km, have a compression and leak-down test done. A used replacement engine from a post-2016 car or a low-mileage non-affected year is often more cost-effective than an in-situ piston ring rebuild. DIY difficulty: Workshop only — requires engine disassembly.

• Erratic idle or sudden stalling
• Car enters limp mode — reduced power, won't rev past ~2,000 RPM
• Check engine light with ETS (Electronic Throttle System) warning
• Difficulty starting or engine hesitates on acceleration
• Throttle unresponsive or sticks

Affected years: 2001–2008 Gen1 S60 (most acute on 2001–2002 models; later units improved but still fail).

The ETM's internal throttle position sensor contacts wear far faster than designed — Volvo's own analysis found failure rates between 21% and 94% depending on model year, according to the Center for Auto Safety. Rather than a formal recall, Volvo extended the ETM warranty to 10 years or 200,000 km — but on a car that is now 15–25 years old, that warranty is long expired. The Matthews Volvo Site and the Volvo Club UK ETM guide both document the full history and repair options.

Replace the ETM unit and reset/calibrate the throttle via diagnostic software. Used or remanufactured units are available, and specialist repairers can also re-coat the internal contacts to restore function. DIY difficulty: Moderate — the unit is accessible but needs software calibration after fitting.

• Knocking or clunking from the front end over bumps and speed humps
• Squeaking on slow parking-lot manoeuvres
• Car pulling to one side or needing frequent wheel alignments that won't hold
• Vague, imprecise steering feel
• Uneven or accelerated tyre wear
• Metal-on-metal contact sound in severe cases

Affected years: All S60 generations (2001–2018); most commonly reported on Gen1 and Gen2, especially after 80,000–120,000 km on South African roads.

S60 front lower control arm bushings are made from relatively soft rubber compounds that wear prematurely — and South African potholes, speed humps and corrugated secondary roads eat through them faster than European driving cycles. Matthews Volvo Site recommends full arm replacement over bushing-only swaps — the labour cost is almost identical and the result is more reliable. SwedeSpeed forum threads document failures at 80,000–120,000 km across multiple generations. Always do a wheel alignment immediately after the repair.

Replace the complete control arm assembly — not just the bushings. Pressing new rubber into the arm requires a hydraulic press and alignment tooling, and the labour cost is almost the same as a whole arm swap. DIY difficulty: Moderate (full arm swap) to Hard (bushing-only).

• "Soot filter full — see manual" amber warning light
• "Engine service required" message in advanced blockage
• Loss of power and limp mode activation
• Increased fuel consumption
• Excessive black smoke on acceleration
• Repeated filter-full warnings shortly after a forced regeneration (root-cause fault)

Affected years: 2006–2018 diesel models (D3, D4, D5 engines); most commonly D5 (2006–2009) and D4 (2013–2018).

The DPF traps soot and clears it automatically during sustained highway driving. Urban commuters and short-trip use never get the engine hot enough for regeneration to complete — soot piles up until the filter is blocked. A design flaw in the EGR cooler on D4 (2.0L diesel) engines allows coolant to weep into the exhaust path, mixing with soot to create a hard carbon paste that standard regeneration cannot clear. The Volvo Owners Club UK forum documents repeat blockages and limp-mode activation on D5 models. The Volvo Club UK DPF guide covers the regeneration process and root causes in detail. Always diagnose the underlying fault before replacing the filter or it will block again.

First try 20–30 minutes of sustained highway driving for passive regeneration. If that fails, a workshop can run a forced regen via diagnostic tool (R800–R1,500). Before replacing the DPF itself, fix the root cause — EGR valve, EGR cooler, pressure or temperature sensor. DIY difficulty: Workshop only — forced regen requires specialist diagnostic equipment.

• Jerking or shuddering between first and second gear in stop-start traffic
• Delayed engagement when selecting Drive from Park or Reverse
• Gear slipping or transmission "hunting" between ratios
• Harsh, clunky downshifts
• Transmission warning light in more severe cases

Affected years: 2001–2009 Gen1 S60 (Aisin AW55-50/51SN most affected); 2010–2018 Gen2 also reported, usually resolved with a software update.

The Gen1 Aisin Warner AW55-50/51SN Geartronic is known for B4 servo cover wear, causing shift flares and juddering hesitation between first and second gear. The Genuine Volvo B4 servo update kit (IPD USA) is the well-documented fix. Contaminated transmission fluid degrades valve body solenoids over time. For Gen2 models, the adaptive gearbox learns your driving style — if the adaptation memory hasn't been reset after a fluid service or repair, the box can behave oddly. The Matthews Volvo Site walks through when a software reset versus mechanical repair is needed.

Start with the least expensive fix: a fluid service and dealer-level software update. If the problem is mechanical — valve body wear or internal failure — a quality-tested used gearbox from a low-mileage donor is far more cost-effective than a rebuild at dealer rates. See our used Volvo gearboxes for availability. DIY difficulty: Moderate (fluid service only) to Workshop only (valve body, gearbox replacement).
