Market analysis

A used Audi A4 throttle body carries a median asking price of $91, which is 0% higher than the Mercedes E Class at $91. Supply also plays a role: Mercedes E Class has 1,979 priced listings versus 594 for Audi A4, and more listings generally mean more choices and more competitive pricing.
The Mercedes E Class average ($126) runs 38% above its median ($91), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.

Buyer's checklist
What to check before buying a used throttle body
- Distinguish between electronic drive-by-wire throttle bodies and traditional cable-actuated units with Idle Air Control (IAC) valves.
- Check bore diameter and butterfly valve throat for heavy carbon build-up, shaft play, or scoring along the aluminum bore wall.
- Inspect electronic sensor housing cover and connector pins for moisture entry, cracks, or burnt circuit traces.
- Verify coolant heating bypass nipple locations and vacuum port configurations, which vary by vehicle region and emission spec.
