Hello. Just yesterday the ABS anti-skid lights came on in my Volvo XC70. We have had an extreme amount of thawing due to the warm weather and heavy snow we had this winter. I am thinking that there is a dirty sensor or something.

Would anyone have advice as to how I can clean,inspect and turn the warning lights off for the brake system?
Or would this be something better left to the dealer?

 

Its probably a bad ABS module - common.
