Model Year: As of 2005 (5)
Concerns: Battery management.
Information: Battery care and maintenance steps.
The newly defined steps and procedures should be regarded as minimum requirements due to the reduced scope compared to the previous Technical Information and these steps and procedures must be carried out accordingly.
The work procedures are shown graphically in Steps 1 and 6-11 cover the activities and action required for battery care and maintenance in the time period between new vehicle and vehicle handover to the customer.
The procedures apply to both new and pre-owned vehicles.
The Quick overview (Step 1) serves as a guide. It lists the key points for the relevant vehicle usage (e.g. showroom vehicle) and roughly outlines the various steps and activities without going into detail. The actual work must always be performed by following the detailed procedure descriptions (Steps 6 to 11) and the information in the legends.
The steps and procedures for the corresponding individual graphics are listed and explained briefly in the legend (Step 12).
Contents: This Technical Information is divided into the following sections:
1 Quick overview:
Graphic overview of work procedures for...
- Direct vehicles (= vehicle is handed over to the customer within 5 working days following delivery),
- Showroom vehicles (= vehicle remains in the showroom following delivery),
- Stock vehicles: without battery disconnect switch (= BDS),
- Stock vehicles: with BDS,
- Stock vehicles: demo (= show or demonstration vehicle outside a building).
The steps and procedures for vehicle delivery are contained in the summarized versions.

2 Recommended measuring devices and chargers, documentation
NOTE: Required temperature for measuring or charging the battery:
To obtain reliable results, the battery temperature must be above 32 degrees F (0 degree C) when measuring or charging the battery. The vehicle must therefore be exposed to a temperature above 32 degrees F (0 degree C) for at least 12 hours.
If the temperature is less than 32 degrees F (0 degree C): leave the battery or the vehicle in the workshop (heated room) for at least 12 hours. This will ensure a uniform temperature in the battery.
2.1 Measuring devices:
We recommend the following devices approved by Porsche for carrying out the required voltage measurements.
Measurements are taken at the external jump-lead starting point (engine compartment) and at the positive and negative terminals of the additional battery (= battery 2, only if used).
2.1.1 Bosch BAT 121 Main features:
- Voltage measurement, starting power in Percent and "good/not good".
- Display for recharging battery, integrated print function.
- Temperature recording (range input: below/above 32 degrees F/0 degree C)
2.1.2 Midtronics INSPECT 45
Main features:
- Voltage measurement, cold-start current in amps.
- Functional state in Percent and bar chart.
- Display for recharging battery (good/recharged).
- Infrared interface (= print function, data transfer to PC).
2.2 Chargers:
We recommend the following battery chargers approved by Porsche. Batteries are charged using the external jump-lead starting point (engine compartment) or directly at the positive and negative terminal of the additional battery (= battery 2, only if used). Batteries can also be charged using the 12 volt receptable (cigarette lighter) (with Charge-o-mat battery maintainer > showroom or demo vehicles only; the battery is charged under the driver's seat).
2.2.1 Bosch BSL 2470
Main features:
- Charge current of 70 A, mobile charger, vehicle electrical system compatible.
2.2.2 Deutronic DPBL 425B-14
Main features:
- Charge current of 30 and 45 A, mobile charger, vehicle electrical system compatible.
- Suitable for charging and/or vehicle electrical system backup (adjustment work, etc.).
2.2.3 Charge-o-mat II (or later model)
Main features:
- Charge current of 3.5 A, vehicle electrical system compatible.
- Connects to the vehicle electrical system via the cigarette lighter (vehicles without BDS only).
- Ideal for permanent or interval charging (showroom/demo vehicles).
- Available from Tequipment.
2.2.4 Chargers from other manufacturers
The following specifications apply when using chargers from other manufacturers:
- Electronic charger.
- Overcharging prevention.
- Charge current of at least 40 A.
- Vehicle electrical system compatible.
2.3 Documentation:
The measured values must be noted and a decision must be made as to whether or not the battery needs to be replaced (based on voltage measurement upon delivery) in the time period between vehicle delivery and vehicle handover to the customer. The battery I-no. (numeric code below bar code, Figure 1) must also be noted.
These results must be archived (PQIS, vehicle documents, PTEC battery form) for each individual vehicle following vehicle handover to the customer.
The "PTEC battery form" can be used for recording battery data and values and for archiving purposes. The previous "Battery maintenance sheet" is no longer used. Make sure to fill out the battery form in PTEC. The step "Battery: check/maintain according to instructions in the current Technical Information" has been incorporated into the sales check.
3. Concluding work
After removing the battery disconnect switch (or after connecting the battery), the following work, for example, must be completed before starting to drive the vehicle.
Initializing the steering-angle sensor
Re-initialize the steering-angle sensor. To do this, turn the steering wheel at least 20 degrees to the left and right with the engine running. Then drive the vehicle straight ahead until the PSM warning light goes off. The steering-angle sensor segment is now detected again.
Tire Pressure Monitoring (TPM)
Once you have finished working on the vehicle, drive the vehicle for as long as required until the tire pressures are displayed in the instrument cluster.
Teaching Power Windows
With the vehicle doors closed,teach the power windows as follows:
- Actuate the rocker switch to "Close" and fully close the window once.
- Actuate the rocker switch to "Close" again. The upper end position is now stored.
- Actuate the rocker switch to "Open" and fully open the window once.
- Actuate the rocker switch to "Open" again. The lower end position is now stored.
4 Information in the event of a complaint
Complaints:
Information in the event of a complaint
The questions stored in PQIS relating to the relevant FES5/SA4 combination must be answered in the event of a warranty claim or complaint. The battery I-no. (numeric code below bar code, Figure 2) must also be noted must also be entered under "Additional information relating to the correction" in the PQIS free-text field. The battery must be stored in accordance with warranty guidelines.
5 Power supply while the vehicle is in the workshop/diagnosis
NOTE: To maintain the charge state of the battery while the vehicle is in the workshop, a charger must generally be connected during diagnosis and while working on the vehicle for periods of more than 15 minutes (Charge-o-mat battery maintainer is not suitable).
