D5244T15 Engine

Volvo 2.4 D5 (D5244T15) 215 HP – Experiences, issues, fuel consumption and used-car buying tips

Key points (TL;DR)

• Great performance and sound: A legendary five‑cylinder which, thanks to the Bi‑Turbo system, offers excellent throttle response and a brutal 440 Nm of torque.
• Timing belt and auxiliary belt risk: The biggest weakness of this engine is the failure or entangling of the auxiliary (serpentine) belt with the timing belt, which leads to catastrophic engine damage. Replacing it before the factory interval is mandatory!
• Geartronic gearboxes: Excellent for cruising, but they require flushing and oil replacement every 60,000 km to prevent damage to the valves in the valve body.
• DPF and city driving: Frequent, interrupted DPF regenerations in city traffic can cause diesel to mix with engine oil, raising the oil level in the sump to a dangerous point.
• Not for everyone: Maintaining this engine is very expensive (Depends on the market), but in return it can deliver hundreds of thousands of kilometers of reliable long‑distance driving. It is not designed for short urban trips.

Introduction

When someone mentions the brand Volvo, the first association for true mechanics enthusiasts is certainly the famous 2.4‑liter inline five‑cylinder (D5). The engine designated D5244T15 represents the evolutionary peak of this architecture, right before Volvo, under pressure from eco standards, switched to two‑liter four‑cylinder engines only (VEA generation). With 215 HP and two turbochargers in a sequential layout, this powertrain was installed in heavyweights such as the V70, XC60 and XC70 series, as well as the S60 and S80 sedans. Thanks to its distinctive, deep five‑cylinder sound and the feeling of endless power reserves on the motorway, this engine has become a true legend. However, it requires a well‑informed owner and a mechanic who understands its weaknesses and maintenance needs.

Technical specifications

Reliability and maintenance

Does this engine have a timing belt or a chain?

Unlike many competing engines of this displacement, the Volvo 2.4 D5 uses a timing belt to drive the camshafts. In addition, it has a complex multi‑rib auxiliary (serpentine) belt system for the ancillary units (alternator, A/C compressor, power steering).

What are the most common failures on this engine?

Speaking as an experienced mechanic, I must immediately point out the critical weak spot of this engine – the auxiliary belt system and its tensioner. If the auxiliary belt tensioner fails or the A/C compressor seizes, the serpentine belt can snap and, unfortunately, its strands can end up under the timing belt. This causes the timing to jump and leads to severe engine damage (bent valves and broken camshafts). Another known issue are the so‑called swirl flaps in the intake manifold, whose shaft wears out over time and causes oiliness on top of the engine. A frequent occurrence is also the failure of the crankshaft oil seal if crankcase pressure is increased (due to a clogged crankcase ventilation – PCV valve).

At what mileage should the major service be done?

The factory prescribes a rather long interval (often around 150,000 to 180,000 km or 10 years). In practice, however, this is suicide for the engine, precisely because of the aforementioned issues. A serious recommendation from any good mechanic is to do a major service with the *mandatory* original replacement of all idler pulleys and tensioners in the auxiliary drive at the latest at 100,000 to 120,000 km, or every 5 years.

How many liters of oil does this engine take and which viscosity is recommended?

The engine takes about 5.9 to 6.2 liters of oil, depending on how thoroughly it is drained during the change. The factory explicitly requires a thin synthetic oil of 0W‑30 grade that meets the ACEA A5/B5 specification. This oil is important for cold‑start lubrication of both turbochargers and for fast distribution to the hydraulic lifters.

Does it consume oil between services and what amount is considered normal?

Under proper conditions, this diesel engine does not consume oil, and the level will at most drop by 2–3 deciliters on the dipstick between services (which I strictly recommend every 10,000–15,000 km). If the engine seriously “drinks” oil (over 0.5 liters per 1000 km), the problem is usually worn bearings in the smaller turbocharger. Conversely, if the oil level is rising, it means that diesel is entering the sump due to DPF issues (which destroys the oil’s properties).

How long do the injectors last and how reliable are they?

The engine is equipped with modern Bosch Piezo injectors operating at high pressure. In practice, they have proven to be very durable and usually last up to 250,000–300,000 km. However, when they wear out, the symptoms include rough idle, blue smoke on cold start and increased fuel consumption. Replacing piezo injectors is very expensive (Depends on the market), and they usually have to be replaced with new ones because overhauling them is rarely successful in the long term.

Specific parts (Costs)

Does this engine have a dual‑mass flywheel?

The answer depends on the gearbox it is paired with. The rare versions paired with a manual gearbox do indeed have a large dual‑mass flywheel. Replacing it together with the clutch kit is very expensive (Depends on the market), especially on models with AWD (4x4) because it requires removing a significant part of the suspension and drivetrain. On automatics (Geartronic), the system uses a so‑called torque converter and does not have a classic dual‑mass flywheel as in manual cars, although the torque converter will also require an overhaul at very high mileage (350,000+ km).

Does this engine have a turbocharger (or two) and what is their lifespan?

As mentioned, this engine uses a Bi‑Turbo system (two turbochargers – a smaller one for low‑rpm torque and a larger one for higher speeds). This concept completely eliminates the so‑called “turbo lag”. They are not known as a weak point and can easily exceed 250,000 km if the owner changes the 0W‑30 oil on time and does not push the engine hard before the oil reaches operating temperature (an optimal 90°C). Overhauling both turbochargers at once, if needed, is of course a costly job (Depends on the market).

Does this model have a DPF filter or an EGR valve that often clogs up?

Yes, the engine has a complex DPF system along with a large electronic EGR valve. If you use it on short city trips, the DPF clogs very easily. The ECU attempts frequent active regenerations, injecting extra diesel, and the fuel seeps past the piston rings into the sump – this is a common symptom and the driver receives the warning “Engine Oil Level High”. If this is ignored, the engine can start running on its own oil‑diesel mixture and go into runaway (self‑destruction). Physical removal or software deletion is possible, but it is preferable to solve the issue through regular long trips or chemical cleaning.

Does this engine have AdBlue, does it cause problems and how is it maintained?

As a model from the period just before the introduction of strict Euro 6.2 standards, this unit meets the Euro 5 standard and does not have an AdBlue system, so owners fortunately avoid the additional costs of urea pumps and injectors that plague newer two‑liter Volvo/VEA engines.

Fuel consumption and performance

What is the real fuel consumption in city driving?

Realistically speaking, a 2.4‑liter engine with an automatic gearbox and AWD, pushing a body like the 1.9‑ton Volvo XC60, results in merciless city fuel consumption. Depending on traffic density in major world cities, it ranges between 9.5 and even 12 l/100 km in heavy stop‑and‑go driving.

Is this engine “lazy” for the weight of the cars it is installed in?

Not lazy at all. With 215 HP and a massive 440 Nm at low revs, it accelerates very well and moves heavy Volvo chassis without effort. In older‑generation XC90 models, as well as robust XC70 estates, this engine provides impressive in‑gear acceleration and serious pulling power, very useful for overtaking.

How does the engine behave on the motorway and at what rpm does it cruise at 130 km/h?

The motorway is the natural environment for this powertrain. With a long 6‑speed automatic, at 130 km/h the engine spins at just 2,100–2,200 rpm. At that point the five cylinders purr beautifully, there are no vibrations in the cabin, and fuel consumption drops to a very reasonable 6.5 to 7.5 l/100 km, depending on the model’s aerodynamics.

Additional options and modifications

How far can this engine be safely tuned (Stage 1)?

Thanks to an extremely strong engine block whose heritage goes back to the 1990s, this engine handles remapping exceptionally well. With a safe Stage 1 remap it routinely reaches figures of 240–250 HP and up to 500 Nm of torque. Interestingly, Volvo itself offers a factory software upgrade for it through the Polestar program, and the difference in driving and gearbox responsiveness is dramatically better. Keep in mind, however, that the increased torque puts extra stress on the automatic gearbox.

Gearbox

Which manual and automatic gearboxes are paired with this engine?

The engine is very rarely seen with the M66 six‑speed manual transmission. In over 90% of cases you will find it paired with the powerful Aisin TF‑80SC automatic gearbox (Geartronic), usually in its second generation (the AWD system uses a fifth‑generation Haldex coupling on the rear axle in 4x4 models).

What are the most common failures of the manual and automatic gearboxes?

On automatics, the main problem is the valve body (a set of solenoid valves). The driver will feel the fault as a harsh “jerk” when shifting from P to D, or as a thump in the back when the gearbox downshifts roughly from 3rd to 2nd gear while slowing down for a traffic light when hot. This most often happens to owners who believed the authorized dealer that the gearbox oil is “lifetime”.

At what mileage should the gearbox be serviced and the oil changed?

On Geartronic gearboxes, changing the ATF oil using a machine (flushing the gearbox, i.e. the flush method) is absolutely essential at the latest every 60,000 km. During that service, it is mandatory to reset the oil degradation counter in the diagnostics and perform a “gearbox adaptation”. For AWD models, replace the oil in the Haldex coupling at the same interval.

Buying used and conclusion

What should be checked before buying?

Buying a 2.4 D5 (215 HP) with around 200,000 km on the clock is not too big a risk, provided you know what to look out for:

• Listen to the engine idling (cold): Any rustling or squeaking from the timing side (left side when standing in front of the car) is a serious red flag – the auxiliary drive may be on the verge of failure!
• Check for fuel‑diluted oil: Before the test drive, check the electronic oil level in the engine menu (and the physical dipstick if there is one). If the oil seems very thin or is above the maximum level, be prepared for hefty bills to sort out the DPF.
• Test the Geartronic when hot: You must not test the automatic gearbox for just 5 minutes. Warm the car up properly with at least 30 minutes of city driving. Jerks when hot indicate that a valve body overhaul is due, which is a costly repair (Depends on the market).

Who is it for?

The final verdict is as follows: the Volvo D5244T15 is a long‑distance cruiser and marathon runner. If you need a car primarily for long trips, working abroad, winter holidays and towing boats and trailers, you will hardly find a more durable, safer and more powerful drivetrain on the market. On the other hand, if you need a city car for commuting 5 kilometers to work, avoid this car at all costs – it simply is not designed for “cold starts and waiting in traffic jams”, and it will take revenge with expensive failures of the emissions and fuel‑injection systems.
