Error codes 17887, 16795, 17698
Hello,
I have a 2003 A4 Quattro 1.8t and have received the following error codes: 17887 (brake booster vacuum failure), 16795 (secondary air injection incorrect flow), and 17698 (coolant temp sensor at rad outlet signal weak). Are these issues related or are they three separate issues? Is there somewhere I should begin looking to start troubleshooting the issue(s). Any help would be greatly appreciated. Thanks.

Those don't sound related. Do you have a CEL / MIL? Did you get these codes with a VAGCOM reader? Are they intermittent?

I have a cheap scanner called VAGSCANNER VAG305 from OBD2Tech. I had a CEL engine light on but I cleared it. I have cleared it a few times. Sometimes it will stay out for a day other times a month or more but it always comes back. Thanks for the reply!
