So no fault codes, but did they do any work? Change a sensor, or just scan it and return it?
If no fault code that's the worse case scenario as you have a problem with no diagnosis, so I wouldn't buy that car, if that's the case... Problems with no clear diagnosis end up expensive as it's educated guess work what's causing it and replacing bits randomly to try and fix aint cheap!!!
