שלום לכולם
בתחילת השבוע שעבר (ירד גשם כבד בירושלים) במהלך נסיעה די פרועה שלי, נדלקה לי נורת מנוע בלוח השעונים.
חיברתי לסורק תקלות מדגם MODIS וקוד התקלה שהופיע הינו 15788 או 17588 (לא זוכר בדיוק)
יש למישהו מושג מה אומר הקוד?
דרך אגב, הנורה כבתה לבד לאחר שבוע (לא נסענו ברכב מאז)
תודה לעוזרים

Having come across this strange fault code (pump current), today in Vag-Com, which I had never heard of, some homework was necessary. I found out the following information which I’ve copied below.
Friday,06,July,2007,13:40:17:40776
VAG-COM Version: Release 704.0
Address 01: Engine
Control Module Part Number: 036 906 034 CP
Component and/or Version: MARELLI 4MV 3956
Software Coding: 00031
Work Shop Code: WSC 06441
Additional Info: VSSZZZ1MZ2R026196 SEZ7Z0A1219628
1 Fault Found:
17588 - Linear O2 Sensor; Pump Current: Short to Plus
P1180 - 35-10 - - - Intermittent
Lambda-sensor Type: Broadband, heated.
The Lambda-sensor determines oxygen concentration of exhaust gas.
Oxygen concentration of exhaust gas permits determination of fuel/air ratio in the combustion chamber. The Lambda-sensor uses two electrodes to generate a voltage, which results from the different oxygen content and ambient air. The voltage at the electrodes is kept constant. This is achieved by way of a pump cell, which supplies the electrode on the exhaust side with the amount of oxygen required to maintain the voltage between the two electrodes at a constant level of 450mV.
To re-attain Lambda-sensor voltage of 450mV between the electrodes, oxygen content on exhaust end must be reduced. This involves the pump cell conveying less oxygen into the measurement area. Pump output is reduced until Lambda-sensor voltage of 450mv is re-attained. The component converts the current consumption of the pump cell/miniature pump into a Lambda value and alters the mixture composition accordingly.
If the fuel/air mixture becomes too rich the oxygen content in the exhaust gas falls. With a constant pump output, the pump cell then conveys less oxygen into the measurement area and the Lambda-sensor voltage between the electrodes increases. In this case, more oxygen escapes through the diffusion channel than is conveyed by the pump cell.
The pump output of the pump cell must be increased so that the oxygen content in the measuring range increases. This resets the Lambda-sensor voltage to the value of 450mv, and the current consumption of the pump cell is converted into a Lambda control value by the ECU.
Note.
The pumping action of the pump cell is a purely physical process. The function does not involve the use of any mechanical components. The pump cell is only shown in symbolic form. A positive voltage in the pump cell causes negative oxygen ions to be drawn through the oxygen-permeable ceramic.
Lambda-sensor heater:
After starting the engine the Lambda-sensor should attain minimum operating temperature as soon as possible. To shorten this phase the Lambda-sensor contains a heating element which ensures that, after starting the engine, the ceramic element reaches the necessary temperature after only 20..30s. During the operation, the heating element maintains optimum operating temperature of the Lambda-sensor
