How Much Does It Cost To Have Bmw Plug My Car Into Their Computer?

My 3 series has an intermittent wiper problem and I have been told to go to bmw so they can plug into the ecu and diagnose the fault…
So I dont get ripped off can anyone tell me roughly what is a fair price for simply diagnosing the fault please?
