Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

About the time the AOS was replaced I started getting ODB codes for the cold start system.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I started a project to replace the IMS on my '99 C4 with 186K miles on it last week. When I dropped the tranny I found a loose 2 wire connector near the AOS and a plugged vacuum line. About the time the AOS was replaced I started getting ODB codes for the cold start system. The 996 diagnostic book test process did not give me any info I trust. Air pump runs as expected. Both the good and bad tests failed, operator error :-) After I get this uploaded I will pull the codes again and update this. For some reason the first photo was rotated 180 degrees. It would be great if I can get some suggestions before I decided to move and finish the project. Thanks for your help! FYI: pulling the motor really looks like the best option for the IMS work. I was going to replace the chain guides also but the space needed for me to do the work just is not there. (request to programmer for site , could a save button be added for temporary saving of edits?)

POST 2 / ORIGINAL POSTEROriginal post

The fault codes are p0410, P code 80, secondary air injection sys cyl 1-3 and p1411, p code 208, secondary air injection cyl 4-6 Thanks

POST 3 / ORIGINAL POSTEROriginal post

Thank you Any idea where the plug is? Even with an inspection camera I can't find a socket to stick it in. Hardest area to check is outboard and rear of the AOS. I'll see if I can bend the camera around some tighter corners Thanks again

POST 4 / ORIGINAL POSTEROriginal post

Thanks! It will be next weekend before I can dig in there. I'll let you know if my old eyes can find the socket:-)

POST 5 / ORIGINAL POSTEROriginal post

:-( I popped the alternator out today after cleaning the shop and tools. The change-over valve and the knock sensor both have connectors plugged in. I will keep searching pages in my Bentley manual but have not found anything with what looks like Re/Br on 1 and Re/Bl on 2, yet. Thanks
