The 14 year old Porsche McCarnade turned off with the start and stop function displayed on the instr

I'm the same way, have you solved it?

Reason 1: Generally, vehicles equipped with automatic start-stop function are turned on the start-stop system by default, and suddenly they can't use the stop, which may be the automatic start-stop button on the car by mistake, resulting in the system being closed. Let's check to see if the system is shut down.

Reason two, if your car is a manual transmission of the car shouting, then the automatic start and stop of the enabling conditions will be more complicated, when we park, when the system recognizes hanging neutral, pull the handbrake, release the clutch, these three actions will be started.

The third reason is that the design of the automatic start-stop system is different for different models of various brands, and the automatic start-stop system of the new Passat must meet certain conditions. That is, the seat belt must be fastened, and then the second front left door must be closed and the engine must be started, so see if your manual has any precautions.

Reason 4, the function will not be started in the following cases, the engine does not reach the normal working temperature, the automatic air conditioner does not reach the preset temperature, the battery storage is not enough, the direction of rotation after parking, the vehicle emergency braking, reversing, you can refer to the above points.

Reason five, the failure of the automatic start-stop system, may be because of the line Zheng Hengqing, or it may be due to other reasons that cause the start-stop system to work effectively, at this time it is best to go to the 4S shop for maintenance.

1. Restrictions on the working conditions of the automatic start-stop function:

For example, when the battery power is lower than the limit value, the vehicle air conditioning system is defogging, the pressure in the braking system drops below a certain point, and the vehicle is "slipping" forward or backward, the start-stop system will not extinguish the engine, and if the engine is turned off, it will also restart without delay.

Second, the impact of cold car on the engine:

More than half of the wear and tear of the engine comes from cold starts, and there are some restrictions on the operation of the start-stop system. When the vehicle starts cold, or the engine water and oil temperature do not reach the normal value, the engine will not start and stop automatically, even if the function is activated.

Third, the benefits of the engine:

Vehicles with automatic start-stop functions, starter motors, and batteries have been optimized to reduce downtime and idle wear of the engine, resulting in a longer service life of the engine.

Causes of failure of the Porsche start-stop function:

1.The system was shut down by mistake. Generally, vehicles equipped with automatic start-stop functions turn on the start-stop system by default, and suddenly it cannot be used. It may be that the automatic start and stop button on the vehicle was pressed by mistake, causing the system to shut down. Solution: Check whether the system is shut down;

2.The start-stop function is not enabled. If the car is in manual transmission, the conditions for activating automatic start and stop are a little more complicated. When parking, the system recognizes the three actions of neutral, handbrake, and clutch release before starting. Solution: Check whether the vehicle is in neutral;

3.It's set up differently. Different brands of automatic start-stop systems are designed differently.

In the case of the new Passat's automatic start-stop system, it must meet certain conditions. That said, you must fasten your seatbelt and then tease your finger to close the second front left door and start the engine, so check the owner's manual for any precautionary tease. Workaround:

Adjust according to the car manual;

4.Doesn't meet startup requirements. This function will not be activated in the following cases: the engine does not reach the normal working temperature, the automatic air conditioner does not reach the preset temperature, the battery storage capacity is insufficient, the steering after stopping, the vehicle emergency braking, reversing.

The start-stop system works when a vehicle is stopped due to congestion or an intersection. The driver presses the brake pedal and stops to change gears. At this time, the start-stop system automatically detects the engine idling, and there is no gear; The wheel speed sensor of the anti-lock braking system shows zero; The battery's electronic sensors show that there is enough energy for the next start.

When these three conditions are met, the engine automatically stops. When the signal light turns green, the driver depresses the clutch, and then he can start stopping and start the engine quickly. In automatic transmission models, as soon as you release the brakes or turn the steering wheel, the engine will immediately ignite automatically, and when you press the accelerator, you can immediately start again.

The whole process is in D mode.

Millions of car purchase subsidies.

1. Press the brake pedal of Porsche Yuanyou. 2. Press Porsche's one-button start button. 3. The dashboard of the Porsche lights up, and the power of the whole car is turned on.

4. Press the automatic start and stop button of Porsche to turn off the automatic start and stop function. 5. At this time, if the vehicle stops when the brake is pressed while waiting for the red light, the vehicle will not automatically turn off.

The Porsche Cayenne's automatic start-stop switch is a button with a circle and the word A, this key is used to control the automatic start-stop function, and the operation can be done once when the power is turned on, the specific operation steps are as follows:

1. Press the brake pedal of the Porsche Cayenne.

2. Press the one-button start button of the Porsche Cayenne.

3. The dashboard of the Porsche Cayenne lights up, and the power of the whole car is turned on.

4. Press the automatic start-stop button of the Porsche Cayenne to turn off the automatic start-stop function.

5. At this time, the Porsche Cayenne will not automatically turn off when the vehicle stops when the brake is pressed while waiting for the red light.

Press it to turn off, and the automatic start and stop of the engine is to automatically turn off the engine when the vehicle is temporarily stopped during driving (such as waiting for a red light). When it's time to move on, the system automatically restarts the engine. English name:stop&,startThe intelligent fuel-saving system is a set of systems that control the start and stop of the engine.

Paramela automatic start-stop shutdown method:

1. When the car is just started, the automatic start and stop is on by default, and the light is not on. Press once, the light is on, and it will automatically start and stop and close;

3. This display will be different according to the different models, and some models are displayed as circle A, slashes;

4. In addition, every time the car is re-ignited, the automatic start and stop is turned on by default, not permanently turned off after pressing once.

The reasons for the sudden loss of Porsche's automatic start and stop are: 1. The outside temperature is relatively low, resulting in the battery temperature being too high or too low, causing the self-withering start and stop to disappear or malfunction; 2. The driver accidentally turned off the automatic start and stop.

A 2011 Porsche Panamena with a mileage of about 10,000 km. Customer feedback: the car will automatically stop when starting and stopping, but release the brake pedal will not start automatically, the instrument prompts as shown in Figure 1, and the key needs to be switched on and off again.

Fault diagnosis: 2) Check that the vehicle has no fault code with piwis.

3) The causes of this failure are insufficient time, too high current, too low battery power, too high battery temperature, DC DC converter failure, and low battery power.

4) When the fault phenomenon occurs, we check the actual value of the gateway and vehicle restart through PIWSI, and there is no abnormality.

5) There is no relevant data at this time. Suspecting that the program of the gateway is out of order, we code the whole vehicle of the vehicle, the vehicle is handed over, the power is off, and the fault still exists. However, when encoding the full shouting roller coaster, DME cannot complete the encoding, and the individual encoding cannot be completed, and the system shows that the encoding is not complete, as shown in Figure 3.

6) suspect that vehicle data is not right at this time and can not be coded to DME, need to see if the code that the system gives is consistent, find that the item "start-stop system recovery" is blank, and the code of the original car is "642-start-stop function", as shown in Figure 4.

Troubleshooting: Select the correct encoding: 642. Fault summary: Due to the increase in vehicle programs, it is not necessary to replace parts to solve the problem, and reasonably learn to use the information (actual value) given by Piwis to improve the efficiency of work.
