Common 2003 Porsche 911 carrera cabriolet problems

The Porsche 911 Carrera Cabriolet 2003, like any other car, has its share of common problems that owners have reported. Here are some of the most frequently mentioned issues and their details:

• Electrical System Issues: Electrical system issues can occur in the Porsche 911 Carrera Cabriolet 2003, especially when the battery has gone flat or required a change. On some models, swapping out the battery can cause the car to go into "delivery mode," which disables certain electrical systems like seat warmers, windows, home link, and higher driving speeds. To complete the installation of a new battery, a Porsche diagnostic device is required to "deliver" the car or complete a "loss of battery power" reset via the handover function using a Porsche diagnostic system.

• Cabriolet Windows Out of Step With Door Open: On cabriolet models, if the windows get out of step with the door opening condition and no loss of power has occurred, it is typically caused by the activation of the door handle not being seen by the window mechanism. This problem can be narrowed down to a micro switch in the door handle or lock mechanism. Common causes include the inner door handle micro switch, the outer door handle micro switch, the door latch mechanism micro switch, or the convertible top latch micro switch.

• Bad Service History: When buying a used 911, especially an older version, it is essential to inspect and consider the service history. A bad service history can lead to issues such as bore scoring, which may require a borescope inspection. Cracked coil packs are also a common issue, causing a misfiring engine. Replacements and reinstatements are relatively inexpensive, but it is crucial to address this issue promptly to prevent further damage.

• Faulty Alternator Cables: In some early Porsche 997 models, a faulty alternator cable can lead to a decreased battery life and run-time. Replacing it with an upgraded alternator cable is an easy fix, but routing can be tricky on 997s. It is essential to check with the previous owner about any experienced issues if you're buying the earliest models.

• Damaged Radiators: Coolant radiators and aircon condensers found in the nose of the 997 are prone to leakage. The vents are typically only washed during servicing by a specialist, so radiators in poor condition are an unfortunately common sight. Always check with the previous owner about the state of their radiator, as some may have applied simple modifications to prevent leaking, or if they are not sure, take it to a specialist.

• Chain Tensioner Failures: Chain tensioner failures have been reported on some M96 motors in the Porsche 911 Carrera. If your car is noisy on startup, ensure that your oil level is always at the high-level mark of your dipstick. Installing a deep-sump kit or an Accusump oil accumulator system can protect against unexpected oil pressure drops. The flapper windows on the bottom of the engine are manufactured out of plastic and can break off inside the sump, leading to oil starvation and complete engine failure. Removing the bottom sump and inspecting the oil control windows is the solution, and aftermarket stainless steel windows can be added for added protection.

• Connecting Rod Bolt Failures: The connecting rods used on the 911 Carrera are forged out of steel and utilize a cracked-rod design, which is cheaper to manufacture but may lead to rod bolt failures in high-mileage engines. Consider upgrading to the LN Engineering screw-on oil filter upgrade for added protection.

• Air-Oil Separator Failures: The air-oil separator is an emissions device that draws vapors from the engine crankcase and then sends them back into the engine. When this unit fails, the result is oil sucked out of the engine and into the intake, which may cause the engine to smoke but will not cause immediate mechanical damage. Regular maintenance and inspections can help prevent these failures.

Is the Porsche 911 a reliable car?

According to motorbiscuit.com, the Porsche 911 is one of the most dependable cars you could own, even more reliable than some traditional options from Honda. It's one of the best choices if you want to purchase a luxury sports car with some history. There are some issues with the Porsche 911, as with any vehicle.

What is the weakness of the Porsche 996?

The rear main oil seals were a weak point on Porsches of this era and leaks are not uncommon. Although the seal itself is an inexpensive part, labour for the replacement is costly because it is very difficult to access. If you spot an oil leak on the 996 you plan to buy, ask a Porsche specialist to look at it.
