Reconditioned Mercedes A-Class 180 CDI/220 CDI Turbo – Ref. A6510900586

Identifying the correct turbo reference for your Mercedes A-Class

Before placing an order, it is essential to check the reference number on the identification plate of your original turbo or on the electronic actuator housing. On the Mercedes A-Class (W176), reference A6510900586 fits in particular the 180 CDI 109 ch and 220 CDI 170 ch engines, identified by engine codes OM 651.901 and OM 651.930. Comparing this number with the one stamped on the removed unit will help you avoid any compatibility errors, particularly between the various variable-geometry turbo variants used on this generation of A-Class.

A reconditioned turbo designed for the reliability of your A-Class

This reconditioned turbo is compatible with reference A6510900586 and has been restored to working order following rigorous inspection procedures, in order to reinstate the boost performance expected from these diesel engines. The A-Class 180 CDI and 220 CDI, frequently used day-to-day in both urban and motorway driving, places considerable demands on its variable-geometry turbocharger, making it essential to choose a reliable part to avoid any further premature failure.

Common causes of failure on OM 651 engines

• Insufficient lubrication due to missed oil changes or unsuitable oil
• A clogged air filter causing contamination of the compressor blades
• Fouling or leaks at the intercooler
• Driving with sudden high-rev bursts without allowing the engine to cool down

Points to check before fitting

• Cleanliness and condition of the oil circuit (feed and return hoses)
• Condition of the air intake and intercooler
• No abnormal play on the turbo shaft prior to installation

When starting up for the first time, it is recommended to prime the turbo with oil before the initial engine start, in order to ensure immediate lubrication of the bearings.
