AUDI Code Compliance & Standards 3 — Questions and Answers
Question 1: An Audi A4 fails an OBD-II emissions inspection because two readiness monitors are 'not ready.' What is the most compliant corrective action?
- Clear codes and resubmit immediately
- Complete the appropriate Audi drive cycle to set monitors (Correct answer)
- Replace the PCM and retest
- Submit a waiver form to the DMV
Correct answer: Complete the appropriate Audi drive cycle to set monitors
Completing the manufacturer-specified drive cycle allows the vehicle's monitors to run and achieve 'ready' status in compliance with OBD-II inspection requirements.
Question 2: Which standard governs the diagnostic communication protocol used by Audi vehicles for UDS (Unified Diagnostic Services) over CAN?
- ISO 14229 (Correct answer)
- SAE J1850
- ISO 9141-2
- SAE J2534-1
Correct answer: ISO 14229
ISO 14229 defines UDS, the diagnostic protocol used by Audi and other OEMs for ECU communication over CAN and other transport layers.
Question 3: A customer requests that an Audi technician disable the speed limiter on a new Audi RS6 for track use. What compliance concern should the technician communicate?
- It voids the federal emissions warranty
- It may violate FMVSS requirements and Audi's type approval conditions (Correct answer)
- It requires ASE Master certification to perform
- It is only prohibited on leased vehicles
Correct answer: It may violate FMVSS requirements and Audi's type approval conditions
Disabling a factory speed limiter can violate FMVSS compliance and the vehicle's type approval, potentially creating liability for the dealer.
Question 4: Under the Clean Air Act, which Audi repair scenario requires the technician to use only EPA-approved replacement catalytic converters?
- Vehicles under 5 years old or 50,000 miles (Correct answer)
- All gasoline-powered Audi vehicles regardless of age
- Only California-registered vehicles
- Vehicles with carbureted engines only
Correct answer: Vehicles under 5 years old or 50,000 miles
The Clean Air Act prohibits replacing OEM catalysts on vehicles within the federal emission control warranty period (5 years/50,000 miles) with non-compliant parts.
Question 5: What is the purpose of Audi's 'Release for Delivery' (Fahrzeugabnahme) checklist in relation to compliance standards?
- To document customer satisfaction scores
- To verify the vehicle meets all safety and regulatory standards before handover (Correct answer)
- To authorize warranty claim submission
- To schedule the first oil service interval
Correct answer: To verify the vehicle meets all safety and regulatory standards before handover
The Release for Delivery checklist ensures all safety, regulatory, and quality checks are completed and documented before the vehicle is handed to the customer.
Question 6: Which federal standard specifies the minimum requirements for Audi's tire pressure monitoring system (TPMS) on vehicles sold in the US after 2008?
- FMVSS 138 (Correct answer)
- SAE J1652
- ISO 21750
- FMVSS 119
Correct answer: FMVSS 138
FMVSS 138 mandates TPMS on all passenger vehicles sold in the US from 2008 onward, requiring warning when tire pressure drops 25% below recommended.
Question 7: An Audi technician notices a repair order requires R&R of the catalytic converter on a 2-year-old vehicle under the federal emissions warranty. Who bears the repair cost?
- Vehicle owner (wear item)
- Audi dealer (goodwill policy)
- Manufacturer (federal emissions warranty) (Correct answer)
- State emissions testing station
Correct answer: Manufacturer (federal emissions warranty)
The federal Clean Air Act requires manufacturers to warrant emission control components for 2 years/24,000 miles (major components 8 years/80,000 miles), making this Audi's responsibility.
