Mercedes M276 Camshaft Adjuster Set – Intake & Exhaust
The Mercedes M276 camshaft adjuster is a hydraulically actuated vane-type phaser that sits at the front end of each camshaft, governing how far and how fast the ECU can advance or retard valve timing in response to engine load, speed, and temperature conditions. On the M276 V6 — whether the naturally aspirated 3.5L or the twin-turbocharged 3.0L variant — there are four of these units in total: M276 Intake Camshaft Adjuster Left, M276 Intake Camshaft Adjuster Right, M276 Exhaust Camshaft Adjuster Left, and M276 Exhaust Camshaft Adjuster Right. Each position carries its own OE part number and is not interchangeable between banks or between intake and exhaust. This full set covers every revision supersession across M276 engine production from 2011 through 2019.
The M276 platform appears across a wide range of Mercedes-Benz chassis — W204, W205, W212, W213, W166, W222, C218, R172, and more — meaning demand for these adjusters spans a large and active vehicle parc. Workshop technicians dealing with cold-start rattle, timing-related fault codes (P001177, P002177, P001685, P001885), or confirmed adjuster wear will find that all four positions are covered by the OE numbers listed on this page. Sourcing the complete Mercedes M276 VVT camshaft adjuster set in a single order eliminates the common problem of mismatched revisions between banks — something that can cause residual timing correlation faults even after replacement.

Note for procurement: Always confirm the OE number on the original unit before ordering. All four positions carry different part numbers — they are not interchangeable. The intake and exhaust adjusters share the same external appearance but have different internal vane geometry.
Mercedes M276 Camshaft Adjuster – Product Display
The following video presents a visual overview of the Mercedes M276 Camshaft Adjuster, allowing buyers to examine the external structure and overall configuration of the camshaft phaser used in the M276 variable valve timing system.
The video shows the component supplied for Mercedes 3.0L and 3.5L M276 engines, including adjusters corresponding to the M276 Intake Camshaft Adjuster Left / Right and M276 Exhaust Camshaft Adjuster Left / Right positions. By viewing the gear profile, housing design and assembly layout, workshops and distributors can quickly verify the structure of the product before installation or resale.
For engine rebuilders and parts distributors, this product display helps confirm the configuration supplied as part of the Mercedes M276 Camshaft Adjuster Set, ensuring compatibility with common Mercedes platforms such as C-Class, E-Class and ML series models.
Why Workshops & Distributors Source Direct From Factory
The M276 adjuster is a known high-attrition part across the Mercedes-Benz vehicle parc — particularly in markets where extended oil change intervals are common or where vehicles have accumulated 100,000 km or more. This drives consistent, repeat demand from workshops, fleet operators, and engine rebuilders rather than one-off retail sales. Sourcing from our production facility directly means:
- OEM-specification tolerances on vane rotor clearance, oil port geometry, and sprocket tooth profile — the areas where worn pattern-shop copies tend to diverge.
- Matched revision supply — when a full set of four is ordered, all units come from the same production batch, eliminating the risk of mixed revisions across banks.
- Stable availability — unlike European distributor stock, which can run short during peak demand periods, factory-direct supply is drawn from our own production schedule.
- Consistent QC process — each adjuster undergoes dimensional checks and functional inspection before packing. Non-conforming units are rejected at production, not discovered on the bench.
- Flexible order quantities — we supply individual pieces, paired sets (e.g., intake left + right), and full four-piece sets, accommodating both single-vehicle repairs and bulk distributor orders.
- Traceable part numbers — every shipment is documented with the OE cross-reference numbers above, supporting your own catalogue and fitment data.
We do not hold consignment stock in Europe. Lead time depends on production schedule at time of order, and this is communicated clearly before purchase. For distributors placing regular volume, we can discuss scheduled production runs.
When M276 Camshaft Adjusters Need Replacement
The Mercedes M276 Camshaft Adjuster operates through hydraulic oil pressure to regulate camshaft phase. With increasing mileage, wear in the internal locking mechanism or vane chambers can reduce the stability of the Mercedes M276 VVT camshaft adjuster. In workshops, replacement is usually considered under several typical conditions.
- Cold start rattle: A short metallic rattle during the first seconds after start-up is a common symptom. When the internal locking pin can no longer hold the camshaft in its parked position, the phaser may move briefly until oil pressure stabilises.
- VVT-related fault codes: If camshaft timing deviates from ECU commands, diagnostic systems may record P0011, P0012, P0014 or P0015. These codes are frequently linked to worn camshaft adjusters or unstable VVT operation.
- Timing system service: During major timing chain repairs or engine rebuilds, many technicians replace the full Mercedes M276 Camshaft Adjuster Set A2760503600 A2760503700 A2760503800 A2760503900 to maintain consistent valve timing across both cylinder banks.
FAQ
1. What is the function of the Mercedes M276 Camshaft Adjuster?
The Mercedes M276 Camshaft Adjuster alters the camshaft phase angle using hydraulic oil pressure. This allows the engine ECU to optimise valve timing for torque, emissions and fuel efficiency.
2. Should all four camshaft adjusters be replaced together?
Many workshops recommend replacing the complete Mercedes M276 Camshaft Adjuster Set during timing system service to avoid uneven wear between banks.
3. Can a faulty camshaft adjuster trigger fault codes?
Yes. The ECU may detect camshaft timing deviation and record codes such as P0011, P0012, P0014 or P0015.
4. Are these camshaft adjusters compatible with both 3.0L and 3.5L M276 engines?
Yes. The Mercedes M276 VVT camshaft adjuster design is used across both displacement variants.
5. What happens if a camshaft adjuster fails completely?
If the internal locking mechanism fails, the camshaft timing may drift, causing rough running and engine fault codes.
6. Are intake and exhaust camshaft adjusters different on the M276 engine?
Yes. The engine uses separate phasers for intake and exhaust camshafts. These include the M276 Intake Camshaft Adjuster Left / Right, along with corresponding exhaust adjusters installed on the same cylinder banks.
