Product Number: MAF-178
The MAF-178 is a replacement Mass Air Flow Sensor (MAF) designed to restore accurate air metering across a wide range of Opel and Vauxhall diesel-engined vehicles. Covering 65 vehicle applications spanning model years 2004 to 2015, this sensor is engineered to integrate directly into the intake system and deliver the precise airflow readings that the engine management unit requires for correct fuelling and combustion control.
As an engine management sensor, the MAF-178 replaces the original mass air flow sensor when symptoms of failure - such as erratic idling, poor throttle response, or increased fuel consumption - present themselves. The extensive coverage across 42 Opel applications and 23 Vauxhall applications means a single reference resolves the majority of 1.7 CDTi fitment requirements within the Astra platform family.
The MAF-178 is cross-referenced against 26 original equipment and aftermarket part numbers, including references from Bosch (0 281 002 832), Hella (8ET 009 149-151), NGK (94366), Mobiletron (MA-B196), Motaquip (LVMA474), Quinton Hazell (QM929), Meat & Doria (86215), and original Opel and Vauxhall references 93188724 and 55561301, among others. This breadth of cross-reference confirms genuine OE-grade interchangeability for the applications listed.
Fitment spans the Opel Astra Classic (L48) range in hatchback, estate, and saloon body styles, covering 1.7 CDTI engines with engine codes including A 17 DTJ, A 17 DTR, and Z 17 DTJ from January 2009 onwards, as well as a broader spread of Opel and Vauxhall models across the full 2004-2015 application window.
