SQRF4J16 Engine

Chery 1.6 TGDI (SQRF4J16) – Experiences, issues, fuel consumption and used car buying guide

Introduction and engine applications

The engine with the code SQRF4J16 represents the third generation of Chery ACTECO engines. This power unit was designed to compete with European and Japanese rivals, focusing on high thermal efficiency (over 37%) and reduced exhaust emissions. It is most commonly found in modern SUVs such as the Chery Tiggo 7 Pro, Tiggo 8 Pro and vehicles of the Exeed brand.

Unlike older Chinese engines, which were often copies of Mitsubishi units, this 1.6 TGDI was developed in cooperation with renowned engineering companies (such as AVL from Austria) and represents a serious technological step forward, offering an impressive power-to-displacement ratio.

Reliability and maintenance

Timing system: chain or belt?

The SQRF4J16 engine uses a timing chain (silent chain) for valve timing. This is great news for owners, as there is no fixed replacement interval like with a timing belt. The chain is designed to last the “lifetime of the engine”, but in practice this usually means it should withstand over 200,000 km with regular oil changes. A symptom of wear is metallic rattling during a cold start.

Most common faults and issues

Although the engine is mechanically robust, experience has shown a few points to watch out for:

• Electronics and sensors: Occasional faults with fuel pressure sensors or oxygen sensors (lambda probes) can occur, which will trigger the “Check Engine” light.
• Carbon buildup: As with any GDI engine (direct injection), the valves are not “washed” by fuel. Over time, soot builds up on the intake valves, which can lead to rough running and power loss at higher mileage.
• Thermostat and coolant leaks: On some early production batches, minor leaks were recorded on the thermostat housing.

Service intervals and oil

An oil service is recommended every 10,000 to 15,000 km (or once a year). Due to the turbocharger and direct injection, exceeding this interval is not recommended.

Oil quantity and type: The engine takes approximately 4.5 to 5 liters of oil (always check the dipstick). Only fully synthetic oil of grade 5W-30 or 0W-20 is recommended (depending on climate and the manufacturer’s recommendation for the specific market), meeting API SN/SP standards to prevent LSPI (Low Speed Pre-Ignition).

Oil consumption and spark plugs

In general, this engine does not consume oil in significant amounts between services. Consumption of up to 0.5 liters per 10,000 km is considered acceptable, especially if driven aggressively. Higher consumption may indicate an issue with the turbocharger or piston rings.

Spark plugs: Due to high injection pressure and turbocharging, iridium spark plugs are used. The recommended replacement interval is every 40,000 to 60,000 km. Worn spark plugs can cause ignition coil failures.

Specific parts (costs)

Dual-mass flywheel: Yes, this engine in combination with the DCT gearbox does have a dual-mass flywheel. Its role is to absorb vibrations and protect the gearbox. Its lifespan is usually around 150,000–200,000 km, but aggressive city driving can shorten it. Replacement cost is high (depends on the market).

Injection system: It uses high-pressure direct injection (200+ bar). The injectors are precise and generally durable, but sensitive to poor fuel quality. Replacing a single injector can be expensive.

Turbocharger: The engine uses a single turbocharger (usually Honeywell or a similar reputable brand) with electronically controlled wastegate. Service life is long with regular maintenance and proper cooldown of the engine after spirited driving.

EGR and emissions: This engine has a catalytic converter, and newer versions (especially for the EU market) also have a GPF (Gasoline Particulate Filter). The GPF rarely clogs if the car is regularly driven on the open road, but frequent short city trips may require regeneration. There is no AdBlue system because this is a petrol engine.

Fuel consumption and performance

City driving: Although the manufacturer promises low figures, reality is different. In a heavy body (like Tiggo 7 or 8), real-world city consumption ranges between 9.5 and 11.5 l/100 km. In heavy traffic it can go up to 13 liters.

Is the engine “lazy”? Absolutely not. With 290 Nm of torque available from just 2000 rpm, the engine pulls very convincingly. The acceleration feels linear and strong, more than adequate for overtaking and dynamic driving.

Highway: This is where the engine shines. At 130 km/h, thanks to the 7th gear, the engine spins at around 2,200–2,400 rpm. This results in quieter cruising and fuel consumption of about 7.5 to 8.5 l/100 km.

Additional options and modifications

LPG conversion: Since this is a direct injection (GDI) engine, installing a regular sequential LPG system is not possible. A dedicated system for direct injection (which also uses a small amount of petrol to cool the injectors) or a liquid LPG injection system is required. These systems are very expensive (often over 1000 EUR), and cost-effectiveness is questionable unless you drive very high mileage.

Chiptuning (Stage 1): The engine has potential. A safe remap can raise power to about 215–225 hp and torque to 330–340 Nm. However, caution is needed due to the load on the DCT gearbox – too much torque can shorten clutch life.

Gearbox: 7-speed DCT

This engine is standardly paired with a 7-speed automatic dual-clutch gearbox (DCT/DSG type). The key point is that this is a gearbox with wet clutches. The manufacturer is most often Getrag (or under license).

• Reliability: Wet clutches are significantly more durable and resistant to overheating in city traffic compared to dry clutches. The gearbox shifts quickly and mostly smoothly.
• Most common issues: Possible juddering when taking off or hesitation at low speeds (software-related). Mechanical mechatronics failures are rarer, but possible at high mileage.
• Maintenance: This is critical. The gearbox oil and filter must be changed every 60,000 km. If this is neglected, repair costs are very high.
• Clutch replacement cost: A clutch kit for this gearbox is expensive and replacement is complex.

Buying used and conclusion

When buying a used vehicle with the 1.6 TGDI engine, pay attention to the following:

1. Cold start: Listen for any chain rattling during the first 3–5 seconds after startup.
2. Gearbox: Test the car in stop‑and‑go city traffic. The gearbox must not bang, jerk or hesitate when shifting into R (reverse) or D.
3. Service history: Check whether the gearbox oil has been changed on time (if the car has over 60k km).

Conclusion: The Chery 1.6 TGDI (SQRF4J16) is a modern, powerful and technologically advanced engine that offers excellent performance for its class. Its biggest advantage is the value for money, along with the reliability of the timing chain and the wet-clutch DCT gearbox. It is aimed at drivers who want the power of a modern turbo petrol engine and are ready to accept somewhat higher city fuel consumption and strictly follow service intervals.
