I took my car to Arnolds for a minor service ahead of selling it and got told my flickering oil light was the pressure, which in turn was the crank and that the whole lot would be 30k more. Instead of agreeing I asked for a quote & took the car elsewhere where they confirm the oil lights was just the switch and that Arnolds had not even checked the oil pressure. Cost me R1200 to get a new switch and drove fine afterwards. Needless to say I never got called with Arnolds quote. Watch out!
