2004 Volkswagen Passat P0352 P0300 and P0301 - Emissions Failure and Misfire Issues
My 2004 Volkswagen Passat failed the emissions test due to persistent engine misfires. The diagnostic trouble codes detected are: P0352 (Ignition Coil 'B' primary/secondary circuit fault), P0300 (random/multiple cylinder misfire detected), and P0301 (cylinder 1 misfire detected). I'm wondering if this issue can be resolved with a simple repair or if it requires more extensive work. Any advice on the most effective fix for these codes in a 2004 Passat would be greatly appreciated.
What engine size do you have? Is it 1.8L, 2.0L, or 2.8L? This can help determine the most likely cause of the misfire and ignition coil issues.
