What the reviews say

• W211 E270 CDI owners describe the engine and automatic transmission as relatively sound; the SBC system and costly electronics cause greater concern.[3]one sourceW211
• Condition depends heavily on maintenance and history: verified mileage and proper servicing may deliver trouble-free use, while an unclear past can bring early repairs.[3]one sourceW211
• Experiences with 2002 W211 E270 CDIs vary: one owner had repeated injector failures, while another covered 50,000 km without engine trouble.[2]one sourceW211
• The W211 has extensive, potentially expensive electronics; buyers should not accept a seller’s claim that a fault merely needs a fuse.[3]one sourceW211

Typical faults

• An early 2002 W211 E270 CDI suffered repeated injector wear, producing loud clatter, rough running and frequent limp-mode activation.[2]one sourceW211

  2002–2002 · 2.7 CDI

• One W211 E270 CDI suddenly lost its instrument lighting, clock and central locking, then stopped recognising the key and would not start.[1]one sourceW211

  2.7 CDI

• A 2004 W211 E270 CDI showed intermittent indicator faults: signals could flash on the wrong side or stop working altogether in damp weather.[4]one sourceW211

  2004–2004 · 2.7 CDI

• An owners’ forum identifies the SBC braking system as the W211’s main trouble spot; buyers should establish whether it has already been replaced.[3]one sourceW211

Which engine and version to take

• The 2.7 CDI can be a sound choice with documented maintenance: owners rate its engine and gearbox above the SBC and electronics, but injector history is essential.[2][3]W211

What to avoid

• Avoid an early 2002 W211 E270 CDI with clattering injectors or repeated limp mode unless diagnosis and completed repairs are convincingly documented.[2]one sourceW211

What to check at the inspection

• Check VIN-based service history, actual mileage and stored faults with Mercedes diagnostics; require defects to be fixed rather than accepting a seller’s explanation.[3]one sourceW211
• With the engine cold and warm, listen for injector clatter, assess smoothness and check during the road test that limp mode is not triggered.[2]one sourceW211
• Operate both indicators repeatedly; inspect the rear SAM, tailgate module and tow-socket area for moisture and corrosion.[4]one sourceW211
• Repeat the starting test and check both keys, instrument lighting, clock and central locking; a combined failure can leave the car unable to start.[1]one sourceW211
• Establish the SBC repair or replacement history and have the braking system diagnosed before purchase.[3]one sourceW211
