VW Crafter EV Key Antenna Fix Needed for Start System

Had similar signal interference problems with my VW ID.4 (2021). The vehicle antenna system was failing intermittently, causing keyless entry malfunctions and start button issues. The diagnostic showed antenna module faults in the front bumper area. Initially thought it was just loose connections, but thorough testing revealed a damaged automotive antenna unit. Simple car radio or external antenna replacement would not fix this, the keyless system uses separate dedicated antennas. The repair required: Complete removal of front bumper, Replacement of main vehicle antenna module, Recalibration of the keyless entry system, Full system diagnostic reset This was a significant repair job taking nearly a full day. The antenna system is integrated with multiple vehicle functions, so proper diagnosis and complete replacement was necessary. After the fix, all keyless functions returned to normal. For your Crafter EV, recommend getting the antenna system properly diagnosed at a specialist familiar with VW electric vehicles. Given the symptoms and mileage, its likely the same antenna module failure that affected many VW EVs from that production period.

Thanks for sharing your experience with the ID.4 antenna issue. Curious how the repair has held up since then? Your repair process sounds similar to what my mechanic suggested for the Crafter. The fm antenna and keyless entry problems have gotten worse over the past weeks. The diagnosis fee alone was quite steep at my regular shop. Would you mind sharing what the total repair cost was in your case? Also wondering if you had any signal interference issues pop up after the fix was done? My current quote seems high but if it actually solves the vehicle antenna problems long-term, it might be worth it rather than dealing with constant keyless system failures.

Following up about my ID.4 antenna repair, great news is everything has worked flawlessly since getting it fixed. The antenna mount and connections were properly secured during the repair, and the keyless entry system has been rock solid. Final cost came to 95€ for fixing what turned out to be a damaged cable connection at the antenna module. Much simpler than expected, no need for complete system replacement in my case. This was a relief since initial quotes were significantly higher. The radio signal strength is actually better than before, and zero signal interference issues since the repair. The mechanic found the root cause quickly, a partially detached connector that was causing the intermittent antenna failures. For your Crafter, definitely get a second opinion if the quote seems excessive. While these systems are complex, sometimes the fix is straightforward like in my case. The key is finding a shop that knows how to properly diagnose vehicle antenna problems in VW electric models.

I finally got my Crafter fixed last week and wanted to share my experience. After getting multiple quotes, I found a certified VW specialist who properly diagnosed the automotive antenna system. Turns out the vehicle antenna module had water damage, likely from a small seal breach. The repair involved: Removing front bumper section, Replacing corroded antenna components, Installing new weather sealing, System recalibration Total cost was 780€ including parts and labor. More than expected, but less than the initial quotes from other shops. The fm antenna reception is now perfect and the keyless entry works consistently again. The mechanic showed me the damaged parts and explained how water intrusion caused the progressive signal failure. Been about a week now with zero issues, no more fighting with keys or dealing with unusual system failures. Really glad I went for the full repair rather than trying cheaper partial fixes. The car feels like new again and all wireless functions are working as they should.
