P308D00 Code: Meaning & Diagnostic Guide

Audi’s DTC list defines P308D00 as “Throttle Transfer Fuel Pump (FP) Engine speed too low.” The reference does not identify a vehicle model, year, or BEV/PHEV application; no explicit 2021+ Audi BEV/PHEV applicability was verified.

Reference status: This page preserves source-backed code definitions for discovery. Manufacturer/model applicability, repair steps and safety conclusions are not treated as verified unless a manufacturer-specific verified report is available.

Is P308D00 generic or manufacturer-specific?

P308D00 has a generic source-backed definition in this database. The exact vehicle make, model, year and powertrain should be confirmed before using a definition for diagnosis.

P308D00 symptoms

A diagnostic code identifies a detected condition; it does not by itself prove which component has failed. Symptoms can differ between vehicles. Record the exact warning message, any additional codes, and the operating condition when P308D00 appeared.

Possible causes of P308D00

Possible causes depend on the vehicle-specific definition and test results. Do not conclude that a named component has failed from P308D00 alone; wiring, connections, control conditions and component tests should be evaluated using manufacturer procedures.

How to diagnose P308D00

  1. Confirm the exact P308D00 reading with a compatible scan tool and record any accompanying codes.
  2. Confirm the vehicle make, model, model year and powertrain before applying a reference definition.
  3. Prefer a verified manufacturer-specific report when one is available.
  4. Follow the manufacturer diagnostic procedure before replacing parts.

How to fix P308D00

There is no safe universal parts-replacement fix for P308D00 without vehicle-specific evidence. The correct resolution depends on the confirmed definition and diagnostic test results.

Can I drive with P308D00?

A universal drive/no-drive answer cannot be inferred from P308D00 alone. Follow the vehicle warning and manufacturer instructions.
