ABS / ASC bye bye in thick snow... Happen to you?

[Eric]

Since I got it about five years ago, my ti has had the ABS and ASC lights come on (with no ABS or ASC function) four or five times, all after driving in heavy wet snow / slush. All returns to normal after a thaw (usually a few days).

I have assumed that snow is packing around one of the wheel sensors (probably rear), but never tried to find it (who wants to lie in wet snow screwing around under the car?), but the last three times this has happened have all been this year, and even though it's fun fishtailing around spraying slush and doing doughnuts, I'm getting tired of not having ABS and ASC at exactly the times when I most need them.

Anyone had this happen?

Any advice?

Thanks,

- Eric
