Question 3

An Audi with adaptive air suspension (air ride) shows the vehicle sitting low on one corner after overnight parking. What is the most likely cause?

Accepted Answer

Leaking air strut bladder or solenoid valve

A single-corner sag overnight points to an air leak at the strut bladder, air line, or corner solenoid valve rather than a compressor fault.

Question 4

When replacing spark plugs on an Audi 3.0T TFSI supercharged V6, why must the engine be cold before removal?

Accepted Answer

Hot aluminum cylinder heads can strip threads as plugs are removed

Answer

Audi's aluminum cylinder heads are prone to thread damage if spark plugs are removed while the metal is thermally expanded.

Question 5

What is the purpose of the 'basic setting' procedure performed on Audi throttle bodies after replacement or cleaning?

Accepted Answer
