The code A1698205689 corresponds to the amplifier used in certain Mercedes-Benz vehicles. Specifically, it is associated with the 2006 Mercedes CLK500 W209 Coupe1. If you’re experiencing audio issues in your 2006 CLK350 coupe, where the radio turns on but there’s no sound, here are some troubleshooting steps you can consider:
Fiber Optic Loop: The problem might be a break in the fiber optic loop. This could be caused by issues with the CDC (CD changer), the amplifier, or even a physical break in the fiber optic wiring anywhere in the car. You mentioned using a fiber optic bypass loop (lollipop), which is a good way to check if the issue is related to the CDC. However, make sure to plug it into the wiring harness, not just the back of the CDC itself1.
Amplifier Replacement: If the issue persists, consider replacing the amplifier. The part number for the original amplifier associated with code A1698205689 is A1698208089. Swapping the amplifier might help restore sound12.
Head Unit and Wiring: Additionally, check the head unit (radio) and ensure that all wiring connections are secure. Sometimes, a loose connection can cause audio problems.
Remember that diagnosing car audio issues can be complex, and it’s essential to rule out each component systematically. If you’re unsure, consider seeking professional assistance from a qualified mechanic or an automotive audio specialist. Good luck with resolving the issue! 🚗🔊
