Industry Best Practices Flashcards

When servicing a VW DSG (dual-clutch) transmission fluid, what best practice applies?

Answer: Use the VW-specified DSG fluid and check level at the specified fluid temperature using ODIS

DSG level checks are temperature-dependent and require the specified fluid for proper clutch and mechatronic operation.

What is the correct practice for coolant in a VW that specifies G13 or G12evo coolant?

Answer: Use the specified VW coolant type and mix with distilled water to the correct ratio

VW coolants are formulated for compatibility with engine materials, and distilled water prevents mineral deposits.

Why is it best practice to replace the timing belt tensioner and idler pulleys along with the timing belt?

Answer: Worn tensioners or idlers can fail and destroy the new belt and engine

Tensioner and idler bearings wear with the belt, and their failure can cause belt slippage and engine damage.

What does a technician do when a VW part carries a 'parts return' requirement under warranty?

Answer: Tag and store the removed part per VW procedures for possible return

Warranty parts must be retained and tagged so the manufacturer can request them for analysis and claim validation.

Which practice prevents cross-threading when installing a spark plug in an aluminum VW cylinder head?

Answer: Start the plug by hand, then torque to specification

Hand-starting ensures proper thread engagement, and correct torque prevents damage to soft aluminum threads.

After completing a repair, what final best practice confirms the customer's concern is resolved?

Answer: Perform a road test or functional check and confirm no fault codes remain

Verifying the repair under the conditions that caused the concern prevents comebacks.

What is a key reason to keep the shop floor clean of oil and coolant spills?

Answer: To prevent slip-and-fall injuries and environmental contamination

Spills are a leading cause of shop injuries and can enter drains, violating environmental regulations.
