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.
