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.
Moisture accumulation within instruments can be traced to small leaks at the windshield and can usually be resolved without removing the glass.
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.
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 spur gear drive area is prone to leaks; the seals/gaskets can be replaced without removing the transmission.
The hydraulic components for the clutch release mechanism at the clutch pedal can fail and cause a low, limp pedal feel.
Tire wear (especially in the rear tires) can be rapid and handling will suffer if the problem is not addressed.
Fluid leaks at the right rear corner can often be traced to the radial seal at the power steering pump.
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.
In order to avoid ABS, Tiptronic, or intermediate differential faults/warning lights, correct tire profile and wear must be maintained.
A failing cylinder head temperature sensor can cause erratic running or the engine to cut out entirely.
If the engine won't turn over or cuts out at seemingly random times, it may be a failing relay for the DME system.
In early models, the alternator/fan belts and bearing at the pulley must be correct. Updated parts are required for the alternator/fan pulley, as well as the belt tension monitor.
Pay close attention to secondary ignition system components (distributor caps, rotors, cables, and connectors).
