Timing chain kit M271 CGI for Mercedes-Benz

OE spec timing chain kit, engineered for Mercedes Benz vehicles with the M271 CGI, direct-injection turbo, petrol engine. Restores precise valve timing, quiet starts and reliable performance after chain stretch or guide wear. Sold per kit, variant specific to engine code and year.

What this is / isn’t:
Included: Primary timing 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 M271 CGI. This kit is not for M271 Kompressor supercharged engines, hardware and chain pitch differ. Model years may use revised guides or tensioners, always confirm by OE part number.

Key Features:

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

• Quiet operation: Hardened pins and low-friction guide faces help reduce start-up rattle.

• 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 minimise seepage after reassembly.

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

Compatibility:
Common applications with M271 CGI direct-injection turbo, confirm by VIN/OE:

• C Class W204 C180 CGI, C200 CGI, C250 CGI

• E Class W212 early E200 CGI, E250 CGI

• GLK X204 200 CGI where fitted

• SLK R172 early 200 CGI
  Markets and years vary, always match by VIN.

Options, engine variations:

• Early vs late M271 CGI → tensioner and guide updates, verify supersessions.

• Emissions or market packages → hose routing and cover seals can change, confirm contents before ordering.

Typical OE reference families, guide only:
A271 050 … timing chain, A271 052 … tensioner, A271 052 … guides and rails, with supersessions by year.
Always order by the exact OE number on your vehicle or confirm via VIN.

When to replace a timing chain kit:

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

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

• Retarded cam timing on scan data, rough running, poor fuel economy.

• Metal debris in oil filter, worn guide material found during service.

Installation notes, pro tips:

• Use correct crank and cam locking tools, follow factory timing marks and torque specs.

• Replace single-use fasteners, crank bolt and cam bolts where specified.

• Clean sealing faces, apply approved sealant to the front cover, allow cure time.

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

• Clear adaptations, perform a road test, recheck for leaks and stored faults.

What’s included / not included:
✅ Timing chain, guides and hydraulic tensioner, front cover seal or gasket where supplied
❌ Oil, sealant, crank bolt, cam phasers, sprockets, water pump, belts, auxiliary hardware unless listed

Q&A
Q1: Does this kit stop the cold start rattle?
Yes, when rattle is caused by chain stretch or worn guides. Ensure the correct tensioner and precise timing setup.
Q2: Do I need special tools?
Yes, cam and crank locking tools and a torque-angle gauge are required to set timing accurately.
Q3: Can I reuse the crankshaft bolt?
Not advised, it is typically torque-to-yield. Replace with new where specified.
Q4: Will this fit a Kompressor M271?
No, Kompressor and CGI use different parts. Match by VIN and engine code M271 CGI.
