When owning a Porsche, it is just a matter of time before you will need the use of a good OBD II Diagnostic Scanner Tool. The scanner will allow you to read and clear trouble codes any time you encounter a “check engine light” or CEL error.
Check Engine Light (CEL) Errors
If you encounter a CEL error, take the time to read the error code as soon as possible. The check engine light alerts you whenever there is a problem with one of the components or systems in your Porsche Boxster.
However, if you encounter a “flashing CEL” error, pull over, stop the car at once (turn the engine off) and arrange to have your car towed.
With a flashing CEL, you can read the error code with an OBD II scanner tool with the key in the “ACC” location but do not start or run your engine.
Is it safe to drive your Porsche Boxster with the CEL Warning On?
If you experience a CEL error, you need to get the CEL code read ASAP. Many drivers carry an OBD II scanner tool in their Boxster. You need to watch the code and be prepared to stop your Boxster if the CEL warning commences flashing. Never drive your Boxster with a flashing CEL. If your Boxster has a flashing CEL you need to turn off the engine and have the Boxster towed for service.
If the CEL light is on and your Boxster appears to be driving normally with no difference in performance, you need to read the CEL code with an OBD II reader tool. Once you obtain the code you can then make an informed decision on whether to drive the Boxster.
It is very common for the incorrect closing of the gas cap to cause a CEL error. This can happen out of haste or unfamiliarity with using the Porsche gas cap. When fueling your Boxster, you need to turn the gas cap until it clicks over 2-5 times to ensure that the gas cap has a good (and thorough) seal.
If your CEL error is related to the EVAP system, you should reset the CEL code, check the gas cap for proper closure and drive your Boxster to determine if the CEL error is a persistent problem (reoccurs).
Porsche Diagnostic OBD II Scanner Tool
You will need the use of a Porsche-specific OBD II tool to reset any OBD “check engine light” CEL warnings. An OBD II scanner will identify any fault codes and clear them.
The OBD II scanner tool is your first step in diagnosing any issues with your car. This tool will pay for itself the 2nd time you use it.
You will also require this tool to reset the Oil Change light when it occurs and to reset OBD oil mileage each time you do an oil change.
If you are a Porsche Club member, and we highly recommend it, you can make use of the club for advice. Porsche Club members can be asked for local advice on getting their CEL codes read and cleared. Other Porsche Club members are often happy to help and are ready with advice.
Porsche Boxster OBD II Port Location
The OBD II port location is located under the dashboard, beneath the left of the steering wheel column.
1. Porsche Integrated Workshop Information System (PIWIS)
The primary diagnostic scanner tool for the Porsche Boxster is the Porsche PIWIS. We refer it to as the “Porsche Hammer”. The Porsche PIWIS is the most powerful diagnostic tool for all Porsche vehicles.
The Porsche PIWIS is used at Porsche dealerships for diagnosis, troubleshooting, and programming. It is not a practical purchase, it is very expensive and has a very steep learning curve. The PIWIS is available on a long-term lease from Porsche for $12,000 USD per year.
2. Durametric Diagnostic Tool for Porsche
Another tool is the Durametric Diagnostic Tool for Porsche. It is a great tool for Porsche mechanics. The Durametric Diagnostic Software is an alternative to the Porsche PIWIS dealer scanner.
The Durametric Diagnostic Tool for Porsche provides in-depth troubleshooting and has great model coverage. There are multiple license options, including a single-car license that is locked to the VIN.
Unfortunately, the Durametric Diagnostic Tool for Porsche costs several hundred dollars and requires a laptop to run.
Durametric has an Enthusiast Kit starting at $287 USD that supports up to 3 cars and is locked by the VIN of each car. This is the best tool and assures full compatibility with your Porsche. Their support is exceptional.
You can buy the Durametric Scanner here (directly from Durametric.)
