Starting today the ESP,BAS,ABS came on and tonight I've been reading the posts about the problem, and some say replace the K40 relay. The ABS icon is on in yellow in the tach screen. also.

There is a relay on the K40 module. Should I change the relay since that would be the cheapest thing to do I would think, or is everyone replacing the K40 module including the relay?
Last week we started having an issue of the dash lights blinking as the AC fan cuts out and the radio cuts out. This happens for just two seconds only, and the engine never died.

The dealer replaced the break light switch two years ago when they replaced the brake fluid reservoir so I'm trying to rule that out for now.

Relay or K40 module? If you think relay, do you know which relay number or could it match the fuel pump relay in the trunk. I replaced it after reading last week about the dash light problems.
