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:
Geometry: Correct chain pitch and guide profile for accurate cam timing and long life.
Construction: Hardened pins and guide faces.
Stable tension control: Calibrated hydraulic tensioner maintains chain load across rpm and temperature.
Seal: New front cover seal or gasket where supplied.
Fitment: Replacement components, to be installed using the 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.
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.

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.
Condition: New aftermarket replacement part. Not an original Mercedes-Benz part; brand and model names are used only to show fitment.
