VW Eos Transmission Grinds with Dead Gear Display
Summary of the thread
The 2013 VW Eos experienced issues with the electronic gear display and transmission, including grinding noises and an unresponsive gear selector. The problem was traced to a faulty control module and sensor in the gear selector mechanism, causing incorrect data transmission and affecting both the display and transmission behavior. The recommended solution involved replacing the gear selector position sensor, reprogramming the transmission control module, and updating the instrument panel software. Seeking diagnosis and repair from a VW specialist with expertise in transmission electronics was advised to prevent further damage and ensure a lasting fix.

Thanks for sharing your experience. Those transmission electronics issues sound exactly like what I am dealing with now on my Eos. The automotive electronics symptoms are identical, dark gear indicator display and unresponsive gear selector. Did you remember roughly what the total repair cost was? Also wondering if you have experienced any similar sensor problems since having it fixed or if the solution has been permanent? Getting the right diagnosis seems crucial here before spending money on potentially unnecessary transmission work. Think I will follow your advice about finding a specialist who really knows these automotive electronics systems.

After getting the repairs done at a certified transmission specialist, the gear indicator display fault was completely resolved. The technicians diagnosed a defective control unit that was causing both the gear selector issues and dashboard display problems. Total cost came to 1000€ for replacing and programming the faulty control module. The car dashboard now shows the gear positions perfectly and the transmission shifts smoothly. No grinding sounds or sensor problems have occurred in the two years since the repair. The gear selector also feels responsive again, exactly like when the car was new. This type of electronic repair really needs proper diagnostic equipment and expertise. The investment in fixing it properly was worth avoiding potential transmission damage. These control unit issues typically dont reoccur once properly addressed with genuine parts and correct programming.

I finally got this fixed last week. Found a highly recommended transmission specialist who actually took the time to properly diagnose the issue. Turns out the digital display and gear shift problems were caused by a failing control module, just like you described. The electronic display is now working perfectly and shows all gear positions clearly. The grinding noise is completely gone and the shift knob moves smoothly between positions. Total repair cost was 1250€ including parts, labor and reprogramming the new control unit. The mechanic showed me the worn-out sensor components they removed and explained how the faulty signals were causing both the transmission and display issues. Really glad I avoided going back to my regular shop, as this definitely needed someone with specialized diagnostic equipment and transmission expertise. It has been running great for the past week with no sensor problem or shifting issues. Feels like a completely different car now. Thanks again for steering me toward getting it properly diagnosed by a specialist.

Had the same issue on my 2010 VW Passat TDI. The instrument panel gear indicator went dark and the gear shift became problematic. The initial diagnosis revealed multiple error codes related to the transmission control module. The root cause was a faulty sensor problem in the gear selector mechanism, which affected both the display and transmission behavior. The grinding noise during shifts was happening because the control unit was receiving incorrect position data from the compromised sensors. The repair required: Replacing the gear selector position sensor, Reprogramming the transmission control module, Updating the instrument panel software This was definitely a serious issue that needed immediate attention, as continued driving could have caused permanent transmission damage. The grinding sounds are a clear warning sign of the system not properly engaging gears. Most important is addressing this quickly, the sensor problem typically progresses and can lead to complete transmission failure if ignored. Would strongly recommend having it diagnosed at a VW specialist who has experience with DSG/automatic transmission electronics rather than a general mechanic.
