First time poster. Please let me know if im in the right thread. Ive replaced the JBE once before because of clicking later to find that the CAS module is at fault. Im getting the CAS cloned atm and im wondering, being semi confident in my solder skills, what is likely the cause of the clicking. As many posters i have tail lights on after key is out and no start on warm days.

 

What fault codes are stored in the many ECUs?

 

thats just the thing no codes. The cas module fixed the issues but im still curious

 

Glad you found the fix!

Were you using a code reader or scan tool that reads BMW fault codes?
