RADIO AERIAL ANTENNA AMPLIFIER SIGNAL BOOSTER
Part Number: 8P3 035 225 / 8P3035225
Factory-fit aerial amplifier module for the compatible Audi A3 8P 3-door rear aerial system.
This listing has been deliberately narrowed to the fitment that could be confidently verified rather than advertising an unnecessarily broad year range.
CRITICAL FITMENT CHECK - PLEASE READ BEFORE ORDERING
This is the NO-SUFFIX 8P3 035 225 aerial amplifier.
Do not order purely because your vehicle is an Audi A3 8P.
Different aerial modules were installed depending on body style, module position and radio/navigation equipment.
YOUR VEHICLE SHOULD PASS ALL OF THESE CHECKS:
1. Audi A3 8P / 8P1 3-door hatchback.
2. Within the verified 2004, 2005, 2006 or 2007 application period.
3. Existing module shows 8P3 035 225 with no letter suffix.
4. Module is the left-lower aerial amplifier position.
5. Connector arrangement and metal mounting bracket visually match our photographs.
6. Radio/navigation equipment is compatible with the applicable PR-code range shown further below.

VERIFIED PARTS COMPATIBILITY CHART
Years are deliberately shown individually so buyers can clearly identify the verified application.
Exact part-number and equipment matching remains essential.
| MAKE / MODEL | BODY | YEAR | FITMENT |
|---|---|---|---|
| Audi A3 8P / 8P1 | 3-door hatchback | 2004 | CONFIRMED RANGE - exact module/equipment must match |
| Audi A3 8P / 8P1 | 3-door hatchback | 2005 | CONFIRMED RANGE - exact module/equipment must match |
| Audi A3 8P / 8P1 | 3-door hatchback | 2006 | CONFIRMED RANGE - exact module/equipment must match |
| Audi A3 8P / 8P1 | 3-door hatchback | 2007 | CONFIRMED RANGE - exact module/equipment must match |
ENGINE / FUEL NOTE:
the strongest catalogue data identifies this component by vehicle body and radio/navigation equipment rather than by a single engine.
Petrol or diesel engine type alone must therefore not be used to decide compatibility.
OTHER VEHICLES:
no additional make or model has been added as a confirmed broad application because the strongest exact-part catalogue evidence identifies this fitment within the A3 8P family.
This conservative approach is intentional to reduce incorrect orders.
DO NOT ASSUME FITMENT TO THESE VEHICLES / PART NUMBERS
| APPLICATION | STATUS |
|---|---|
| Audi A3 8PA 5-door Sportback | Not advertised as confirmed for this exact no-suffix unit. Check the removed module. |
| Audi A3 Cabriolet 8P7 | Not confirmed by the verified application data. |
| Audi A3 8L | Different vehicle generation - do not order based on A3 name alone. |
| Audi A3 8V | Different vehicle generation. |
| Audi S3 8P | Not advertised as a blanket fit. Only consider if the removed unit is the exact same part number and physical configuration. |
| 8P3 035 225 B | Different module reference. The B-suffix unit is associated with a different aerial-amplifier position/configuration. Do not substitute automatically. |
| Other 8P3 035 225 letter suffixes | Do not assume interchangeability. Radio/antenna specification can differ. |
RADIO / NAVIGATION EQUIPMENT REFERENCES
The catalogue application for this part is associated with the following equipment / PR-code references.
Vehicle equipment can vary even within the same year, which is why matching the removed module remains the safest buying method.

WHERE IS THE PART FITTED?
This aerial-amplifier configuration is identified as the LEFT-LOWER module in the rear hatch/tailgate aerial system. Access is normally obtained by carefully removing the relevant inner hatch/tailgate trim. Always confirm the physical location and module number before disconnecting anything.

WHAT DOES THE AERIAL AMPLIFIER DO?
The rear-window aerial system receives radio-frequency signals but the signal reaching the radio can be comparatively weak. The aerial amplifier forms part of the signal path and conditions/amplifies the received aerial signal before it reaches the vehicle's radio/navigation equipment.
A correct replacement therefore needs the appropriate electrical configuration, connector arrangement, mounting position and radio-equipment compatibility. A part that merely looks similar or has a closely related number should not automatically be treated as interchangeable.
POSSIBLE SYMPTOMS OF AN AERIAL-SYSTEM FAULT
• Weak FM/AM reception compared with normal.
• Fewer radio stations found during an automatic scan.
• Static, noise or intermittent radio reception.
• Signal drop-outs in areas where reception was previously reliable.
• Reception that changes when the rear hatch is opened or moved.
• Poor reception despite the radio/head unit otherwise functioning normally.
• Fewer radio stations found during an automatic scan.
• Static, noise or intermittent radio reception.
• Signal drop-outs in areas where reception was previously reliable.
• Reception that changes when the rear hatch is opened or moved.
• Poor reception despite the radio/head unit otherwise functioning normally.
DIAGNOSTIC NOTE:
these symptoms do not prove that this amplifier is faulty.
Similar faults can arise from rear-window aerial tracks, wiring/coax connections, plugs, power or earth supply,
other aerial modules or the radio/navigation unit itself.
Diagnosis before replacing parts is recommended.
WHY MATCHING THE FACTORY-SPEC COMPONENT MATTERS
CORRECT SYSTEM INTEGRATION
A properly matched factory-spec component gives you the connector geometry, mounting arrangement and electrical specification intended for the vehicle's aerial system. That is particularly important on an A3 8P where several closely related amplifier numbers and positions exist.

VALUE VS A NEW REPLACEMENT
A correctly matched pre-owned factory-spec component can offer substantial savings while keeping an existing serviceable part in circulation. On selected car parts, savings may be as much as 70% compared with a new equivalent; actual savings depend on the component and current new-part price.

A very low-cost unverified replacement can be a false economy if the connector configuration,
mounting position or electrical specification is wrong.
Matching the number and the photographs before purchase is the best way to avoid buying twice.
FITTING GUIDE
PLANNING GUIDE ONLY:
this is not a factory workshop procedure. Fasteners and trim arrangements can vary with vehicle equipment.
If you are not comfortable removing vehicle trim or diagnosing electrical systems, professional fitting is recommended.
TYPICAL TOOLS
• Plastic interior trim removal tools
• Small Torx driver / bit set
• Small 1/4-inch ratchet and socket set as required by the fitted hardware
• Small trim pick for connector locking tabs where appropriate
• Protective gloves
• Multimeter useful for electrical diagnosis

TYPICAL INSTALLATION SEQUENCE
STEP 1: Switch the ignition off and protect surrounding trim and glass.
STEP 2: Open the rear hatch and carefully release the appropriate inner hatch/tailgate trim using plastic trim tools.
STEP 3: Identify the left-lower aerial amplifier and verify its label before removal.
STEP 4: Take a photograph of the connector routing so the original arrangement is recorded.
STEP 5: Release the electrical/aerial connectors by their locking tabs. Do not pull directly on the wiring or coax cable.
STEP 6: Remove the amplifier mounting hardware/bracket as required.
STEP 7: Before installation, place both modules side by side and compare the exact number, connector openings, bracket shape and mounting points.
STEP 8: Install the replacement, reconnect all plugs securely and restore any mounting hardware.
STEP 9: Test radio reception across several known stations before fully clipping all trim back into position.
STEP 10: If the fault remains, investigate aerial tracks, wiring/coax, power/earth, related aerial modules and the head unit rather than repeatedly replacing parts.
