TRANS FAIL SAFE Message On

[flyvanoort]

Had the TRANS FAIL SAFE light come on in my 2005 X5 with 105,000 miles on the odometer and thought I would share the outcome.

Here's what the service writer wrote on the work order:
Customer request check electrical system: seat heaters inop "TRANS FAIL SAFE" message on "Brake" light on. Airbag light, fasten seat belt chime sounding with no one in seat. Only 1 day headlights were flashing.

Problem started on Tuesday. I immediately started researching the XOutpost forum and found lots of TRANS FAIL SAFE posts but nothing that matched the problems my SAV was having. I tried to find the cause of the problems throughout the week and realized I couldn't self diagnosis. So, I called my local BMW dealer on Saturday morning at 10:30am they said to bring in the vehicle and they would look at it. Diagnosed and repaired same day while I waited. Out by 1:10pm with a free car wash and some BMW wheel cleaner. Had a great experience with the BMW dealer. I will continue to perform as much of the maintenance on the vehicle myself using this forum for reference but I also know when it's time for help. It's nice to have a positive relationship with my local dealer.
