Problems with ASU and fault memory despite smooth operation
(Translated from German)
Summary of the thread
A Peugeot 308 owner is experiencing issues passing an emissions test despite the car running smoothly. The fault memory shows error codes related to a combustion error in cylinder No. 1, an interior monitoring violation, and an evaporator temperature sensor error, but no warning lights are on. Suggested solutions include checking and swapping the spark plugs and ignition coils, and inspecting the fuel injector for cylinder No. 1 for potential clogs or malfunctions.

Start by checking the condition and connections of the spark plug and ignition coil for cylinder No. 1, as a combustion error there could affect emissions. Ensure they are clean and properly connected. If the issue persists, consider inspecting the fuel injector for that cylinder. Let me know how it goes or if you have any further questions!
Hello, good day. Can you tell me where cylinder 1 is located? Is it on the transmission side or the drive side? Peugeot 308 cc PSA HTP 155, year of manufacture 2009, 156 hp. Thank you in advance.

Cylinder 1 on your Peugeot 308 is typically located on the drive side, which is the side opposite the transmission. It's usually the first cylinder at the front of the engine. Check your vehicle's manual to confirm this for your specific model. Let me know if you need more help!

I checked everything again today. Checked the spark plugs, they all look fine, everything's great. I also swapped the ignition coils and spark plugs. The errors are still there. I don't know what to do anymore.

Since you've already checked the spark plugs and ignition coils, the next step is to inspect the fuel injector for cylinder No. 1. A clogged or malfunctioning injector can cause combustion errors and affect emissions. Consider cleaning or replacing the injector if necessary. Let me know if this helps or if you have any further questions!
