The Mercedes — Benz M113.980 is a 5,439 cc, V8, naturally aspirated petrol engine produced between 2001 and 2006. It features a double overhead camshaft (DOHC), 32 — valve configuration, and Bosch Motronic ME 2.1 electronic fuel injection. In standard form it delivered 225 kW (306 PS) at 5,600 rpm and 460 Nm of torque, with a focus on smooth, high — revving performance for luxury sedans and coupes.
Fitted to the W220 S — Class and C215 CL — Class models, including the S500 and CL50…
Production years 2001–2003 meet Euro 3 standards; specific certification varies by market (VCA UK Type Approval #VCA/EMS/7895).
The Mercedes-Benz M113.980 is a 5,439 cc V8 naturally aspirated engine engineered for full-size luxury models (2001–2006). It combines DOHC valvetrain architecture with Bosch Motronic ME 2.1 sequential fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 3 emissions standards, it balances refinement with mechanical reliability.

The Mercedes-Benz M113.980 was used across Mercedes-Benz's W220/C215 platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations-reinforced mounts in the C215 and compact intake routing in the W220-and from 2006 the facelifted W221 models adopted the M273 engine family, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M113.980's primary reliability risk is camshaft and follower wear on early builds, with elevated incidence in high-mileage or poorly maintained vehicles. Internal Mercedes-Benz quality reports from 2004 noted a significant number of pre-2003 engines requiring camshaft replacement before 140,000 km, while UK DVSA historic vehicle inspection data links mechanical wear to improper oil selection in preserved examples. Sustained high-load operation and extended oil intervals increase cam and lifter stress, making oil quality and maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M113.980 offers smooth V8 performance and refinement, but early models (2001–2002) are prone to camshaft wear if maintenance is neglected. Later revisions (post-2003) improved camshaft durability with better materials. When properly maintained with correct oil (MB 229.1, high-ZDDP) and regular service, these engines can reliably exceed 180,000 km.
Key issues include camshaft and lifter wear (especially pre-2003), idle instability from IACV or vacuum leaks, coolant leaks from water pump, and ignition timing drift. These are documented in Mercedes-Benz service bulletins and verified through technical workshops. Proper maintenance significantly reduces failure rates.
The M113.980 was used in the W220 S-Class (S500) and C215 CL-Class (CL500). It was phased out in 2006 with the introduction of the M273 engine family. All applications were rear-wheel-drive platforms requiring premium fuel and balanced performance.
Limited tuning potential exists. Modifications include high-performance camshafts, upgraded intake manifolds, and ECU remapping. Some enthusiasts add performance exhausts or throttle bodies, but this compromises OEM integrity. Output gains are modest (10–15 kW) due to DOHC and 4-valve limitations.
Moderate for its era. In a W220 S500, typical consumption is ~13.8 L/100km (city) and ~8.6 L/100km (highway), or about 27 mpg UK combined. Driving style significantly impacts efficiency—smooth operation yields better results. Expect 25–30 mpg (UK) on mixed roads for a well-tuned M113.980.
No. The M113 series uses a non-interference valvetrain design. If the timing chain fails, piston-to-valve contact is unlikely, minimizing catastrophic damage. However, timing chain wear should still be monitored to maintain valve timing accuracy and prevent secondary mechanical issues.
Mercedes-Benz specifies SAE 10W-40 or 5W-40 oil meeting MB 229.1 specification. High-ZDDP (zinc dialkyldithiophosphate) content is essential to protect the flat-tappet camshaft. Oil changes every 10,000–15,000 km are recommended to ensure long-term durability.
