My driver side DRL stopped working. I replaced the Tms module with the passenger side in attempt to see if the issue is in the TMS - it was working just fine. So I purchase a new TMS module for the driver side. I encoded it and thought it using ISTA+. It works until I turn off the vehicle. When I turn it back on - the halo ilia not working. If I encode it again - same thing - works until the vehicle is off - then it stops working. Any thoughts what can cause the car not to remember the coding? Or could it be something else? ISTA+ tells me there are no other error codes. Just the two related to the RDL: 805cf8 and 805cf9.
