VW Taos Multiple Error Messages Point to Control Issue

Had a similar issue with my 2020 VW Tiguan a few months back. Have some experience working on cars but definitely needed professional help with this one. The multiple error messages turned out to be related to incorrect coding in the main control module. The fault codes kept appearing even after basic diagnostic resets. The malfunction indicator lights were constantly triggering across different systems. Took it to a workshop where they performed a complete diagnostic scan. They found that after a previous service, the vehicle coding was not properly updated. The check engine light and various system warnings were basically false alarms due to mismatched software parameters. The fix required specialized diagnostic equipment to reprogram the control module with the correct coding parameters. Total repair cost was 360€ and took about 3 hours to complete. What trim level is your Taos and has it had any recent service work or updates? Also, which specific error messages are you seeing? This info would help determine if your issue matches what I experienced. Consider getting a professional scan done as generic code readers might not access all the needed diagnostic data for these types of system-wide issues.

My Taos was last serviced at 60000km about 2 months ago. The scan tool readings showed P0106 and P0113 codes, but the engine light keeps coming back even after clearing them. The message patterns match exactly what you described, multiple systems showing errors simultaneously. The dealer mentioned potential sensor issues but wanted 580€ just for additional diagnostics. Starting to wonder if this might be related to the coding update they did during the last service, similar to your case. Anyone else faced this specific fault code combination on a relatively new VW with recent service history?

Still dealing with VW error codes myself. After the update fix I mentioned before, learned something important about these specific codes youre seeing. P0106 points to the MAP sensor and P0113 to the IAT sensor, both can trigger exactly the kind of multiple system warnings we experienced. Running my OBD-II scanner again showed these sensors sometimes throw false codes after control module updates. The engine light kept returning on my Tiguan until the dealer properly recalibrated the sensors alongside the coding update. The 580€ diagnostic fee seems steep considering the similarity to my coding issue. The workshop that fixed mine first checked the update logs which confirmed the coding mismatch. Worth asking if they can verify the last update was properly completed before diving into sensor replacements. A full system diagnostic scan would definitely show if youre dealing with the same root cause. These fault codes can cascade through multiple modules when the base programming is off, causing those infotainment and cluster warnings we both saw.

Thanks for the input. After reading about similar experiences, I took my Taos back to the dealer and specifically asked them to check the coding from the last service update. Turns out you were right, the malfunction indicator lights were triggering due to an incomplete software update. The dealer found that the control module needed a proper reset and recalibration. They ran a complete OBD-II diagnostic scan which showed the P0106 and P0113 codes were indeed false readings. The check engine light finally stayed off after they corrected the coding parameters. Total cost ended up being 290€ for the diagnostic work and recalibration. Much better than the initial quote and possible sensor replacements. The whole fix took about 2 hours. For anyone else seeing multiple error messages after a service update, definitely have them verify the coding was completed correctly before replacing parts. The fault codes can be misleading when the base programming is mismatched.
