Possible Body control module problems
What are the pre-emptive signs of an impending body control module failure? On a recent trip I got a 'memory malfunction' error but it didn't set a CEL. I was getting doubtful outside temp readings but I understand that the 230 body has strong heat soak problems. Does this sound like
a BCM impending failure?

The R230 does not have a body control module. The memory malfunctions are usually a light out, low fluid level, something like that. Outside temperature is usually the sensor or it's wiring. It sits in the lower bumper on the left side.

Thank you for the info. I changed the temp sending unit before my 1,300 mile trip and I still got unusual readings. In most situations where the actual temp was 90 degrees, the car would show 112 for 10 minutes after moving the car. It was very difficult to get an actual reading for most of the time driving. Once the sender
would show 90 (actual outside temp) the gauge wanted to stay in the low 100's . While going down the road I got an SRS warning and then the 'memory malfunction' flash.
