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.

Check Engine Light illumination and performance issues can be caused by oxygen sensor faults.

The accumulation of moisture at major connectors and control units can cause various ABS/PDAS faults due to corrosion.

 

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

Over time, the engine can leak oil at various locations. Early-production vehicles require engine disassembly and modification to resolve leaks at the cylinder heads, oil return tubes, valve covers, timing cover, chain housings, case through bolts, and lines to/from the oil cooler.

The front hood and rear deck lid support struts may fail; replacement is required.

Engine issues related to valve guide wear are common. Oil consumption, smoking at first startup, and valve train noise are all symptomatic of loose guides and worn valve stems. The valve train is complex and should be thoroughly inspected if a problem arises.

The dual mass flywheel can fail and cause symptoms like noise and chatter when operating the clutch and changing gears.

Various repairs and adjustments to the drive mechanism (including cables) are commonly needed on the Cabriolet tops.

Ports and passages for secondary air flow can clog at the cylinder head/cam housing area. Partial engine disassembly may be required to fix the problem.

If engine misfiring, rough running, or fuel consumption issues are not resolved quickly, the catalytic converter can overheat and fail.

Climate control modules can be problematic. Symptoms vary but include failure or persistent dead battery after not using the vehicle for a while.

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.
Wind noise at the front of the car and water leaks at the vent wing are typical problems on Targa models.
Issues with the air flow meter flap or calibration can cause fuel mixture control problems.
