The Parktronic system has been deactivated.

The 2010 350e E class (W212) is a model of the Mercedes-Benz E class that was released in the year 2010. It belongs to the W212 generation of the E class. Greetings, The park sensor switch light spontaneously illuminated yesterday, without any manual activation of the switch. The system is turned off. Upon doing a diagnostic assessment using the iCarsoft tool, it was seen that no sensor issue was detected, contrary to initial expectations. However, an error code A12500 was identified, indicating that the power supply of the sensors is operating beyond the acceptable range. The value provided is 15.1 volts. Could someone provide a translation of the issue, including an analysis of the problem and its potential causes, as well as suggestions for resolving it? The reset function is not functioning. The present circumstances are filled with joy and contentment.

The voltage reading seems to be quite high. It is recommended to use a voltmeter to measure the battery's voltage when the engine is operational, in order to ascertain if the alternator is generating a voltage of 15.1 volts.

[RuthHimmic]

Thank you, I will attempt the suggested approach and assess the outcome.

[RuthHimmic]

Certainly! The battery has been subjected to many tests, and the voltage measured when the engine is operating is 14.7 volts. There are no other visible defects or illuminated warning indicators present. The concealed menu also displays a reading of 14.7 on the battery while in operation. Is the value in question considered too elevated?

The upper limit of the usual range is 14.7.

[MBcarOWNER]

The observed value does seem to be quite elevated. I am curious about the current state of your battery and if you have recently replaced the alternator or other related components. One cost-effective option is to explore an alternate approach by acquiring a pre-owned parktronic module from an online marketplace like as eBay, with the option to return it if it fails to meet the desired functionality.

[RuthHimmic]

Thank you.

[RuthHimmic]

The battery in question is less than two years old. There were no modifications made to the alternator or other electrical components. Do you possess knowledge on the location of the module? I may consider experimenting with that approach or alternatively, I may explore the option of attending a local independent event. Thank you for providing your valuable insight.

[RuthHimmic]

I have conducted a thorough investigation into the whereabouts of the parktronic module, although regrettably, I have been unable to get any relevant information pertaining to the E class W212 350 blue efficiency model. Any assistance about the precise whereabouts of the subject in question would be much appreciated. Thank you for your response.

According to my understanding, the location in question is situated inside the front passenger footwell, specifically positioned on the bulkhead next to the engine compartment. To locate the desired object, it is recommended to carefully fold the carpet, remove the cover, and thereafter inspect the area located behind it.
