Certified Audi TT Specialist — Questions and Answers

Question 1: Which component is commonly upgraded to increase horsepower in an Audi TT?

Lightweight flywheel
Cold air intake
Performance turbocharger (Correct answer)
Aftermarket suspension

Correct answer: Performance turbocharger

Upgrading to a performance turbocharger is a primary method for increasing horsepower in turbocharged Audi TTs. A larger or more efficient turbo allows the engine to compress and force more air into the cylinders. This increased airflow, combined with appropriate fuel delivery and engine tuning, directly translates to a significant boost in engine power and torque output.

Question 2: How should a technician verify a brake systems repair is complete?

Check only the specific component that was repaired
Ask the customer if they notice a difference
If the warning light is off, the repair is complete

Correct answer: Perform a thorough road test, recheck all work, and verify with diagnostic tools

A thorough verification process including road testing, visual rechecking, and diagnostic confirmation ensures the repair is complete and safe.

Question 3: What environmental regulation applies to suspension and steering?

Proper handling and disposal of fluids, refrigerants, and hazardous materials as required by EPA regulations (Correct answer)
Environmental compliance is optional for small shops
Only diesel shops need to follow environmental rules
