Notes

• Compare A2229003300 with the number on your original ballast. The photographed label reads A2229003300 Q01.
• The same label prints 1 307 329 315 15 and 10EEG110011.
• 130732931500, 10EEG110395 and 10EEG141011 are also in the item specifics. The label shows 130732931515 and 10EEG110011.
• Hardware and software numbers in the specifics, HW-NR A2129014406 and SW-NR A2129024008, are not the catalogue part number.
• The title names the A-Class. No A-Class chassis code is in the live fitment.
• Adaptive or AFS systems may still need coding if a warning remains.
• Professional fitting is recommended because of the high voltage.
• Coding: like-for-like new ballast/driver replacements that match the OE part number are typically plug-and-play with no coding required. Always match the number on your original module. Adaptive/AFS headlight systems or used modules may still need coding, initialisation or fault clearing with diagnostic tools if warnings remain.
• Please verify the part number on your original ballast matches A2229003300 before ordering.
• Includes a 1 year warranty covering manufacturing defects.
