If your Audi A6 (2018-Onwards) is currently experiencing:

Reduced engine power
Rough idling
Poor fuel economy
Decrease in acceleration

These could all be a sign your vehicle is experiencing issues with its Mass Airflow Range (MAF). VAG Bolton now offers another specialised service and is now able to identify if you’re experiencing an issue with your Mass Airflow Sensor (MAF) as well as repair the fault.

The P010100/P0101 fault code typically indicates a problem with the Mass Airflow Range (MAF), meaning your vehicle’s computer is receiving inaccurate readings about the amount of air entering the engine, which can lead to performance issues.

Causes for the P010100/P0101 error may include:

A faulty or damaged Mass Airflow Sensor (MAF)
Damaged internal wiring relating to the Mass Airflow Sensor (MAF)

Recent diagnostics conducted at VAG Bolton mean we are now able to identify if you’re experiencing an issue with your Mass Airflow Sensor on any Audi A6 (2018-Onwards). VAG Bolton will identify the cause and replace the parts if necessary. Please contact us to book your vehicle in for an initial fault diagnosis.

VAG Bolton and our extensive diagnostic and repair service which covers the Audi A6 (2018-Onwards) can identify if your vehicle has an issue relating to the Exhaust Gas Recirculation (EGR). If your vehicle is experiencing any of the following symptoms, VAG Bolton can now diagnose your vehicle using our TCM software and identify if you are currently experiencing fault code P040200/P0402:
