1997 Mercedes E420 P0410 Code: How to Fix Secondary Air Injection System Fault
I own a 1997 Mercedes-Benz E420 and recently received a check engine light with fault code P0410, indicating an issue with the secondary air injection system. Can anyone provide guidance on how to diagnose and fix this problem? The P0410 code specifically points to a malfunction in the secondary air injection system, which is critical for reducing emissions during engine warm-up. I'd appreciate detailed steps or recommendations for troubleshooting this common issue in my model year and trim.
I have the same P0410 code on my 1997 Mercedes-Benz C230, so I'm looking for advice on how to resolve this issue as well. The secondary air injection system seems to be a recurring problem in older Mercedes models from that era.
