The Renault G9T 607 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 140 kW (190 PS), with torque figures of 380 Nm, engineered for strong, flexible performance in larger vehicles.
Fitted primarily to the Espace V and Talisman models, the G9T 607 was engineered for refined, effortless cruising…
Production years 2015–2021 meet Euro 6 standards across all markets (VCA UK Type Approval #VCA/EMS/5678).
The Renault G9T 607 is a 2,299 cc inline‑four turbo‑diesel engineered for large MPVs and sedans (2015-2021). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong, linear torque and refined highway performance. Designed to meet Euro 6 standards, it balances power with stringent emissions control.

The Renault G9T 607 was used across Renault's CMF-CD platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts and specific exhaust routing for the Espace and Talisman. All adaptations are documented in OEM technical bulletins.
The G9T 607's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Renault internal service data indicates this as a leading cause for roadside assistance calls for affected models, while owner feedback highlights DPF regeneration issues in urban use. Fuel quality and adherence to maintenance schedules make preventative measures critical.
Analysis derived from Renault technical bulletins (2015-2021) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The G9T 607 offers strong performance but has a known risk with its high-pressure fuel pump. Long-term reliability is heavily dependent on using high-quality, ultra-low-sulfur diesel and adhering strictly to the maintenance schedule, particularly for fuel and oil changes. Well-maintained examples can be dependable.
The most frequent issues are failures of the Bosch CP4 high-pressure fuel pump, DPF clogging (especially with urban driving), and carbon buildup affecting the EGR system. Turbocharger actuator faults are also a documented concern in later mileage vehicles.
The G9T 607 engine was used exclusively in Renault's larger vehicles during its production run. It powered the Espace V (2015-2021) and the Talisman sedan and estate (2016-2021), always badged as the 'dCi 190'.
Yes, the G9T 607 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 220-230 PS and torque to 450-480 Nm. As with any tuning, it's crucial to use a reputable tuner and understand that it may increase stress on components like the clutch and turbo.
Official combined figures for the Espace dCi 190 are around 5.5 L/100km (51 mpg UK). Real-world consumption typically ranges from 6.5 L/100km (43 mpg UK) in mixed driving to over 8.0 L/100km (35 mpg UK) in heavy urban traffic, heavily influenced by driving style and DPF regeneration cycles.
Yes. The G9T 607 is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, resulting in catastrophic internal engine damage requiring a very expensive rebuild or replacement.
Renault mandates the use of RN0720 specification oil, typically a 5W-30 synthetic. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is essential to protect the emissions systems, particularly the DPF, from clogging and premature failure.
