Hi All,

I started getting the SOS Light Warning (uploaded in the URL below) in my 2006 330i for the past 1 week. What could be the reason? Is this a problem? How to fix this? The car has 120K miles as you can see in the picture.

I believe all 06 us 330's came with Logic 7
Anything in the most loop can cause an SOS error.
If you have had a recent rainstorm the first thing to
check is that the Amplifier has not drowned.
If you have a Sat module in addition to the TCU that
can also cause the SOS error.

typical things in the fiberoptic most loop in an 06 us model
include TCU, Sat module and Logic 7 amp.

Logic 7

But seriously. Check the MOST I was going to post a link, but ctuna already shared it.

I was getting an SOS fault warning each time on start up for over a year.

Was never a problem. Just annoying. Drive the car so seldom that I didn't bother trying to figure out how to get rid of it. Took the car into the dealer for the blower motor wiring recall and asked if they knew how to fix it. Blank stares. Said they'd have to diagnosis it for an unknown cost w/o any guarantee that it would get fixed.

Did some research on the Net and one "fix" mentioned was unpairing your phone from the car. So, I just deleted the phone from car's memory and the SOS fault notice warning disappeared.

Problem solved. Worth a try if you haven't tried it yet.

***Solved*** . It was the Satellite DP Module unit that was causing the issue. Once that was replaced, the SOS warning disappeared.
