Detailed Description

Standard Ignition AS734 is an emission control sensor used to measure manifold absolute pressure and send that signal to the engine management system. Accurate pressure input helps the ECU manage fuel delivery, ignition timing, and boost-related control strategies. This part cross-references 2-27468 and EC2248 for the same application. It is a direct-fit option for Audi Q7, Audi SQ7, Audi A6 allroad, Audi A6 Quattro, Audi A7 Sportback, Audi A8 Quattro, Audi Q8, Audi RS Q8, Audi RS3, Audi RS5, Audi RS6 Avant, Audi RS7 Sportback, Audi S4, Audi S5, Audi S6, Audi S7 Sportback, Audi S8, Audi SQ5, Audi SQ5 Sportback, Audi SQ8, Audi TT RS Quattro, and Audi S7 applications listed in the fitment data. The AS734 part number is also useful when matching OE-style replacement needs across these Audi platforms.

What It Helps Address

• Incorrect manifold pressure readings
• Check engine light related to MAP sensor performance
• Rough idle or unstable engine operation tied to pressure signal errors
• Poor throttle response caused by inaccurate intake pressure data
• Fuel trim and drivability issues on Audi engine management systems

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. Confirm the vehicle application by year and model, since AS734 is listed across multiple Audi platforms from 2016 through 2025. Inspect the harness connector and sealing surfaces for damage or contamination before connecting the new sensor. For fitment language, this part fits 2017-2025 Audi Q7, N/A; fits 2020-2025 Audi SQ7, N/A; fits 2020-2024 Audi A6 allroad, N/A; and fits 2019-2024 Audi A6 Quattro, N/A, along with the other Audi applications shown in the fitment table.
