First-time poster, hoping for some help.
I have an 1999 E39 528i which is showing the Transmission fault symbol on my dash (the yellow cog with the exclamation mark within). This came on while travelling and coincided with an airbag warning light, loss of function from the multi-function steering wheel, and the radio going off. I noticed no loss in performance, which many people describe after the Transmission warning light comes on.
Subsequently I've found that activating the vanity lights in the sun screen makes the radio trip out.
So I'm thinking it must be an electrical fault.
I tried changing the appropriate fuzes, but no luck.
Should I get the fault codes read? Anything else I can try?
Any help would be much appreciated.
