Market analysis
Why does the Mercedes S Class throttle body cost more?
A used Mercedes S Class throttle body carries a median asking price of $120, which is 20% higher than the Audi Q7 at $100. Supply also plays a role: Mercedes S Class has 2,707 priced listings versus 670 for Audi Q7, and more listings generally mean more choices and more competitive pricing.
The Mercedes S Class average ($147) runs 23% above its median ($120), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
The Mercedes S Class throttle body is interchangeable across 22 model years versus just 18 for the Audi Q7 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Audi Q7 is 26% cheaper ($100 vs $135) — the gap narrows compared to the overall median difference.
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.
