Pedal Commander for Audi: Choosing the Right Model by Trim

Quick answer

Buy the Pedal Commander kit that matches your Audi's chassis code and engine, not just the badge on the trunk. For many 2.0T and V6 Audi models the shared PC22-AU is the starting point, while trim-specific kits such as the Pedal Commander for Cadillac ATS show how option-level fitment works on other platforms. Verify your engine code and connector type first, then choose the sensitivity range you actually want.

Why Audi trim level changes which kit you need

Audi sells the same body style with different engines, pedal assemblies, and wiring looms depending on trim. A Base A4 and an S-line A4 can share a chassis code but use different throttle pedal connectors, so the kit that fits one may not plug into the other. That is why Pedal Commander lists fitment by vehicle, model years, engines, and trims rather than by brand alone.

The practical rule: identify your chassis code (for example B8 or B9), engine displacement, and trim name from the door jamb sticker or your VIN decoder. Then match all three against the product listing. If your trim is not listed, do not assume it fits just because a sibling trim is covered.

Step-by-step fit check before you order

Work through this sequence once and you will avoid most returns. It takes about five minutes and only needs your registration or VIN.

1) Find the chassis code and model year. 2) Note the engine displacement and fuel type. 3) Confirm the trim name exactly as Audi badged it. 4) Check the product page's listed model years, engines, and trims against your notes. 5) If the listing offers an option selector such as 'Which Audi Do You Have?', choose the exact match rather than the closest one.

• Chassis code and model year first — they narrow the field fastest.
• Engine displacement and trim must both appear in the listing.
• Use the option selector when the listing provides one; it prevents mismatched connectors.
• If your exact trim is absent, contact support before ordering instead of guessing.

What the PC22-AU gives you once it fits

The PC22-AU is a plug-and-play throttle response controller that eliminates the gas pedal's response delay. It offers 36 sensitivity settings and works with the Pedal Commander app on Google Play and the App Store, so you can adjust or switch modes from your phone over Bluetooth. It carries a 2-year product warranty.

For an Audi drive-by-wire upgrade, the value is not more engine power — it is removing the lag between your foot and the throttle body so the car reacts when you ask. That matters most in stop-and-go traffic, on highway merges, and when you want a sharper response without touching the ECU.

How to choose between modes and sensitivity settings

The 36 settings are not 36 different products; they are combinations of driving modes and intensity levels. Start in the middle of the range and move one step at a time. Eco-style settings soften initial throttle input for smoother low-speed driving, while sport-style settings sharpen it for quicker response.

Change one variable at a time and drive for a few days before adjusting again. Sudden jumps to the most aggressive setting can make the car feel twitchy in traffic and harder to modulate in rain. The app makes this easy to fine-tune, but discipline matters more than the number of options.

Where other Pedal Commander kits fit into the picture

If you also own a Land Rover LR3 or a Cadillac ATS, the same fitment logic applies. The Pedal Commander for Land Rover LR3 covers model years 2004-2009 with the 4.0L V6 or 4.4L V8 and Base, HSE, and SE trims. The Pedal Commander for Cadillac ATS covers the 1st Gen 2013-2019 with 2.0L, 2.5L, and 3.6L engines and trims from Base up to V.

The lesson for Audi buyers is that trim-level fitment is normal across the Pedal Commander range. Treat the option selector as a required step, not an optional one.

Decision rules for Audi buyers

• Match chassis code, engine, and trim together: A listing that covers your model year but not your exact trim is not a confirmed fit. Check all three before adding to cart. Three matches or it is not your kit.
• Use the option selector when offered: If the product page asks which variant you have, answer precisely. This is how the seller prevents connector mismatches. Precision here prevents returns later.
• Start mid-range, then adjust one step at a time: With 36 sensitivity settings, the fastest way to a good setup is incremental changes over several drives, not one big jump. Tune gradually for smoother results.
• If your trim is not listed, ask before you buy: Absence from the fitment list is a decision limitation, not a hidden fit. Contact support with your VIN and trim name. No listing, no assumption.

Who should buy which kit

Best for

• Audi owners with a confirmed chassis code, engine, and trim that match a listed Pedal Commander kit
• Drivers who want to reduce drive-by-wire throttle lag without ECU tuning
• Owners who want app-based mode switching and a 2-year warranty

Not for

• Audi owners whose exact trim is not listed and who have not confirmed fitment with support
• Drivers expecting horsepower gains rather than improved throttle response
• Anyone unwilling to verify engine and connector details before ordering
