A normal operating clock may cause the airbag warning lamp to illuminate or a chronic dead battery.
Smoke, oil consumption, and fuel trim issues with various fault codes can be traced to an internal leak at the oil separator.
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.
An accumulation of small air leaks at various locations around the intake manifold/intercooler area can cause performance problems.
Abnormal noises from the intermediate shaft area may be signs of impending engine failure, don't wait to get this issue checked out!
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.
