My trip computer in the dash (drivers cluster) is talking to me. The "A" trip meter reading that’s just above the odometer reading flashes "ILL.5" at me periodically. It flashes about three or four times before the engine is up to temp (3-5 minutes) and then less often, but periodically from then on.
I presume this is an ECU error code? Can anyone confirm what this is? Anyone had this exact code/ problem before?
If this is a standard error code, does anyone have the interpretations for the all the error codes in a Legacy/ Liberty. This model is an MY05 3.0R-B.
Incidentally, this problem only started since having the car into Subaru to fit a towbar this week. I wonder if there’s a relationship there?
I’ll be following up with Subaru, but would prefer to be armed with a bit of knowledge before doing so. The dealers seem to like to keep you in the dark… presumably to foster a dependency on them. That goes against my grain!

Hope someone can give me some pointers.
Cheers,
Deucer.
