Audi Diagnostics and Fault Finding
We are able to perform a diagnostic check on your Audi.
Some of the more common reasons why Audi owners bring their cars to us for a diagnostic check include:
 Fuel emission light / engine management light
Call us to book a diagnostic check on your Audi.
Example: Faulty ECT Sensor
Above Picture: Audi A3 faulty ECT (”Engine Coolant Temperature”) Sensor
What was the problem?
This Audi A3 had a flashing light on its dashboard (engine management system warning light) so came in for a diagnostic test.
A diagnostic test was carried out and the diagnosis revealed a faulty ECT sensor.
What does this mean?
The Engine Coolant Temperature Sensor (ECT) tells the computer the temperature of the engine so that the computer can allow more fuel to be injected
into the engine, or less, according to the temperature.
If the ECT sensor becomes defective, then the ECU (Electronic Control Unit: ie, the car’s computer) will receive the wrong information concerning
the temperature of the engine.
