Creaking noises while driving over bumps and when cornering may be difficult to diagnose, but are usually caused by the windshield at the body/seal area. The latest version seal and/or lubricant can solve the problem.
In order to avoid ABS, Tiptronic, or intermediate differential faults/warning lights, correct tire profile and wear must be maintained.
The front control arms should be regularly inspected for wear at the ball joints and bushings. Ball joint boot cracks/tears can lead to ball joint wear and failure.
Tire wear (especially in the rear tires) can be rapid and handling will suffer if the problem is not addressed.
The release mechanism for the clutch (including the release arm bearings and shaft) can fail and cause stiff, binding, and possibly noisy pedal operation.
The clutch release on early-production vehicles requires modification to make it compatible with newer repair parts.
The hydraulic components for the clutch release mechanism at the clutch pedal can fail and cause a low, limp pedal feel.
The hydraulic fluid for the clutch system may be overlooked; the fluid should be replaced regularly during brake fluid service.
If aging or contaminated fluid is not replaced, there may be problems in the lines and actuating components, as well as clutch issues that are difficult to diagnose.
The spur gear drive area is prone to leaks; the seals/gaskets can be replaced without removing the transmission. 

The constant velocity (CV) boots and CV joints should be inspected at each service. Servicing the torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

A normal operating clock may cause the airbag warning lamp to illuminate or a chronic dead battery.

Using the wrong battery or the failure of a climate control module may cause a chronic dead battery after the vehicle has not been used for a while.
The vehicle central warning display can be sensitive to interference from vehicle ignition faults such as high voltage arcing anywhere in system. Battery capacity must be adequate to avoid electrical issues; also, the battery must be maintained and checked regularly.
Moisture accumulation within instruments can be traced to small leaks at the windshield and can usually be resolved without removing the glass.
