AUDI Blueprint Reading & Interpretation 3 — Questions and Answers
Question 1: On Audi electrical diagrams, what is the purpose of a 'splice point' (S-point)?
- It marks where a wire changes color
- It shows where multiple wires share a common connection (Correct answer)
- It identifies a replaceable fuse location
- It indicates the end of a harness segment
Correct answer: It shows where multiple wires share a common connection
Splice points (S-points) in Audi diagrams show locations where several wires are joined together within the harness.
Question 2: In Audi technical documentation, what does the 'scale' notation '1:2' on a blueprint mean?
- The drawing is twice the actual size
- The drawing is half the actual size (Correct answer)
- Two views are shown for every part
- One inch equals two centimeters
Correct answer: The drawing is half the actual size
A scale of 1:2 means the drawing is drawn at half of the real-world size of the component.
Question 3: Which view in a multi-view technical drawing shows the Audi component as seen from directly above?
- Front view
- Side view
- Top view (plan view) (Correct answer)
- Auxiliary view
Correct answer: Top view (plan view)
The top view, also called the plan view, depicts the component as observed from directly overhead.
Question 4: On Audi repair diagrams, what does the 'J' prefix on a component designation (e.g., J285) indicate?
- A sensor or sending unit
- A control module or ECU (Correct answer)
- A relay
- A motor
Correct answer: A control module or ECU
In Audi's standardized component coding, the 'J' prefix designates electronic control units or modules.
Question 5: What information does the 'parts list' (BOM) associated with an Audi assembly blueprint typically include?
- Only the color codes of painted parts
- Part numbers, descriptions, quantities, and material specifications (Correct answer)
- The technician's repair time estimates
- Warranty coverage dates for each component
Correct answer: Part numbers, descriptions, quantities, and material specifications
A bill of materials (BOM) lists every component's part number, description, required quantity, and material details.
Question 6: When reading Audi collision repair blueprints, what does a 'section cut' line with arrows indicate?
- The direction of impact force during a collision
- The plane along which a cross-sectional view is taken (Correct answer)
- A weld seam location
- A crumple zone boundary
Correct answer: The plane along which a cross-sectional view is taken
Section cut lines with arrows show where an imaginary slice is made through the part to reveal its internal cross-section.
Question 7: On Audi hydraulic system diagrams, what does a triangle symbol pointing toward a line represent?
- A pressure relief valve
- A hydraulic pump
- Flow direction in the line (Correct answer)
- A filter element
Correct answer: Flow direction in the line
A filled triangle (arrowhead) on a hydraulic line indicates the direction of fluid flow through that line.
