my stabil track light ca come on and said to service, how soon should I do this?

You will need to start with a scan of the abs module. Most generic scanners wont do this so you may need to bring it to a shop. Here is a link to help find a shop near you. https://repairpal.com/repair-shops

8° ? .. I must say - you really like to keep one clean! .... I do too but that is a little extreme... Even going through the automatic car wash.. IF (and when) warming temperatures doesn't fix it .... Agree - Professional scan test will be required.
