Timing chain kit M270 with sprockets for Mercedes-Benz

OE spec timing chain kit, engineered for Mercedes Benz vehicles with the M270 1.6 or 2.0 turbo petrol engine. Restores precise valve timing, quiet operation and reliable start up after chain stretch or guide wear. Sold per kit, variant specific to engine code and year.

What this is / isn’t:
Included: Timing chain set, primary chain, fixed and pivot guides, hydraulic tensioner, guide pins or rails, front cover seal or gasket where supplied.

Important: Match by VIN and engine code M270. Early and late M270 units can use different chain pitches, guide designs and tensioners. Transverse platforms may differ from related M274 parts. Always confirm by OE number before ordering.

Key Features:

• OE matched geometry: Correct chain pitch and guide profile for accurate cam timing.

• Quiet and durable: Hardened pins and precision formed rails reduce rattle on cold starts.

• Stable tension control: Calibrated hydraulic tensioner maintains chain load across rpm and temperature.

• Leak resistant service: New front cover seal or gasket where supplied to help prevent seepage after reassembly.

• Exact fitment: Direct replacement components for a no mod install when used with factory timing tools.

Compatibility:
Vehicles with M270 turbo petrol, match by VIN or OE:

• A Class W176 A180, A200, A250

• B Class W246, W242 B180, B200, B250

• CLA Class C117, X117 CLA180, CLA200, CLA250

• GLA Class X156 GLA200, GLA250

Always order by the exact OE part number on your vehicle or confirm via VIN.

When to replace a timing chain kit:

• Rattle at start up or warm idle, chain slap noise from timing cover.

• Fault codes for cam crank correlation, P0016, P0017, or camshaft adjustment range errors.

• Retarded cam timing seen on scan data, sluggish performance, poor fuel economy.

• Metal debris in oil filter, worn guide material in the sump.

Installation notes, pro tips:

• Use proper locking tools for crank and cams, follow factory timing marks and torque specs.

• Replace one time use fasteners, crank bolt and cam bolts where specified.

• Clean sealing faces, use approved sealant on the front cover, allow cure time.

• Change engine oil and filter after repair, use Mercedes approved oil, MB 229.x spec.

Q&A
Q1: Does this kit fix the cold start rattle?
Yes, when chain stretch or guide wear is the cause. Ensure correct tensioner and guides are installed and timing is set accurately.
Q2: Do I need special tools?
Yes, crank and cam locking tools are required to set timing precisely. A torque angle gauge is also recommended.
Q3: Can I reuse the crankshaft bolt?
Not advised, it is usually torque to yield. Replace with new where specified.
Q4: Will this fit M274 engines?
No, M274 is the longitudinal version with different parts. Match by VIN and engine code.
