Stop in for a cup of coffee

Body shop calls for a scan last week. I diagnosed both front crash sensors faulty. Insurance says only replace 1. Gm sensor is $250,aftermarket $90. Its a liability thing, has to use gm.
Called back to scan,other sensor is bad. I make him flip sensors side to side (swapnostics) and see if fault follows which it does.
Almost $700 later it will be fixed. could be all said and done for around $250 with aftermarket sensors including scan. Morons.
the aftermarket sensor is made by the same manufacturer. Double dumbass..
