A recent coding challenge involved troubleshooting a faulty auto up/down window feature. Initial attempts, including various data set adjustments, proved unsuccessful. Hours were spent in the car, meticulously recording measuring values during up/down and auto up/down sequences. Even the window motor overheated twice during this process.
Comparing the coding between the two door controllers, while not identical, revealed a crucial difference. The “light tank” option was enabled on the driver’s side but not the passenger side. This likely stemmed from previous experimentation with VCDS, attempting to identify lighting pin assignments.
Deselecting the “light tank” option and initiating window adaptation resolved the issue. This highlights the importance of thorough VCDS coding analysis when diagnosing complex vehicle problems. Comparing controller coding bit by bit can pinpoint unexpected culprits.
This experience underscores the power of collaborative problem-solving and the valuable insights gained from community forums. Initially, the problem seemed insurmountable, leading to assumptions of mechanical or parameter issues beyond the scope of VCDS. However, a fresh perspective, prompted by another user’s suggestion, directed the troubleshooting towards coding discrepancies. This ultimately led to a successful resolution.
