The code is most rampant on the Renault Laguna II (2001–2007) with the 1.9 dCi 120hp or 130hp unit, but it can appear on any Renault with a vacuum-controlled variable geometry turbocharger (VGT).
If you are not comfortable working on vacuum systems or turbochargers, find an independent garage that specializes in Renault dCi engines – many general mechanics misdiagnose this fault.
In short: MOT 1654 Renault is a turbo overboost code nearly always caused by a vacuum leak or stuck vanes. Diagnose systematically, clean or replace the cheap parts first, and avoid the new-turbo trap. Your wallet – and your Laguna – will thank you.

The Renault 1654 engine is a solid, workhorse unit—reliable, easy to maintain, and well-suited to commercial duties—but shows its age in noise, emissions, and electronic features. Excellent choice where durability and simplicity matter more than modern refinement or emissions compliance.

In the Renault-specific diagnostic lexicon, DF1654 typically refers to a "Multiplexed signal for engine torque" or a fault related to the "Engine torque request signal."
In simpler terms, the Engine Control Unit (ECU)—the brain of the car—is trying to communicate with other systems (like the transmission or ABS) to say, "I am producing this much power." However, due to a wiring issue or a sensor failure, that message is being scrambled, interrupted, or lost.
Because modern Renaults rely on a Controller Area Network (CAN bus) to share data between modules, a break in this communication chain triggers the "MOT" (Engine) warning light.
Keyword Focus: MOT 1654 Renault
If you own a modern Renault—whether it’s a Clio, Megane, Captur, Kadjar, or Scenic—you have likely plugged a diagnostic tool into the OBD2 port at some point. Among the sea of alphanumeric codes that can appear, one stands out for its ambiguity and its direct link to vehicle compliance: MOT 1654 Renault.
For many drivers and even some mechanics, this code causes unnecessary panic. Does it mean an instant MOT failure? Is it a sensor error? Or is it a deep-seated engine management fault?
In this article, we will dissect everything you need to know about the MOT 1654 Renault code. We will cover its technical definition, its impact on the UK MOT test, common symptoms, diagnostic steps, and the exact repair procedures to get your Renault back on the road legally and safely.

The Renault Mot. 1654 is a critical engine timing tool used primarily for locking the crankshaft on various Renault engines, particularly those in the K-Series (1.4/1.6 16v) and F-Series (1.8/2.0 16v) families. It ensures the engine remains at Top Dead Center (TDC) during timing belt replacements to prevent catastrophic engine damage. Technical Specifications
The Mot. 1654 is a Crankshaft Timing Pin designed to thread into the cylinder block to lock the crankshaft web. Function: Locks the crankshaft at TDC.
Engine Families: K4J (1.4 16v), K4M (1.6 16v), F4P (1.8 16v), and F4R (2.0 16v).
Common Applications: Renault Clio, Mégane, Scénic, Laguna, and Espace.
OEM Part Number: Mot. 1654 (often paired with Mot. 1496 or Mot. 1489). Operational Role in Timing Procedures
Renault engines are known for "free-wheeling" pulleys (sprockets without keyways). This means the Mot. 1654 is not just an aid, but a requirement for maintaining timing. 1. Locating the TDC Point
The pin is inserted into a specific threaded hole in the engine block (usually located near the front of the block or behind the starter motor). As the crankshaft is rotated by hand, the crank web eventually rests against the pin, indicating precise TDC for Cylinder 1. 2. Ensuring Accuracy
Unlike generic pins, the Mot. 1654 is precision-machined to a specific length. Using an incorrect pin can result in timing being "out" by several degrees, leading to: Poor idling and reduced power.
Check engine light (CEL) for camshaft/crankshaft correlation. Valve-to-piston contact in extreme cases. 3. Tool Complement
The Mot. 1654 is rarely used alone. A standard timing kit for these engines includes: Recommended tools:
Mot. 1496: Camshaft setting plate (slots into the rear of the cams). Mot. 1490-01: Camshaft sprocket locking tool.
Mot. 1054: An alternative TDC pin used for older 8v or different diesel configurations. Maintenance & Workshop Safety
Hand Tighten Only: The pin should be screwed in by hand to avoid cross-threading the engine block.
No Load Bearing: Never use the Mot. 1654 to hold the crankshaft while loosening or tightening the crankshaft pulley bolt. The pin will bend or snap inside the block. A separate flywheel locking tool (like Mot. 1677) must be used for high-torque applications.
Verification: Always rotate the engine two full turns by hand after removing the tools to ensure no mechanical interference occurs before starting.
💡 Pro Tip: If you are working on a 2.0L Turbo engine (F4RT), ensure your kit includes the correct width setting plate, as the camshaft slots are wider than those on the standard 1.6L K4M engines.
