A 2016 Audi A6 arrived at our workshop for complete diagnostics. The owner wanted several issues checked at once: transmission fault codes, Check Engine warning, squeaking from the right front brake, and the overall technical condition of the car.
With this type of job, it is important not to focus on just one warning light. A transmission fault, Check Engine light, and brake noise can be three separate issues, but they can also reveal the broader condition of the vehicle. That is why we worked systematically.
First, we performed computer diagnostics. The goal was to see which faults were stored in the control units, which were current, and which may have appeared earlier.
We checked:
On an Audi A6, diagnostics must be read correctly. A fault code does not automatically mean that a part has to be replaced. The context must be understood first.
The next part of the job focused on the right front brake system. The owner heard squeaking, so we inspected that area in more detail.
We checked:
Squeaking does not always mean the brakes are completely worn. Sometimes the cause is in the guides, dirt, uneven contact, or early wear.
Alongside the individual complaints, we also checked the general condition of the vehicle. On a car of this class, it makes sense to combine electronic diagnostics with mechanical inspection so the owner gets a clear overview.
The inspection included:
The result was not just an explanation of why a warning light was on. The owner received a clear overview of what should be repaired now and what can be monitored.
Check Engine can relate to the engine, emissions system, sensors, ignition, fuel, or other components. The exact cause can only be confirmed by diagnostics.
Transmission faults can be related to electronics, sensors, oil condition, mechanical wear, or communication between control units. The specific codes must always be evaluated.
The cause may be dirt, rust, uneven wear, a caliper issue, guides, or the condition of the pads and disc.
The 2016 Audi A6 received complete vehicle diagnostics. We checked transmission faults, Check Engine warning, electronics, the right front brake system, and the overall technical condition of the car. The result is a clear overview of faults and recommended next steps without unnecessary blind replacement.
