OMG! Did they actually do that?! I caught my service tech overfilling my oil by about 1 liter. I took it back and when I looked at the invoice at home it said, "removed 1/10th of a liter at customer request" that was a LIE. Either the tech lied to the service manager (who wrote the invoice) to save his job, or the manager lied to me in case my engine was damaged. I my be old and stupid BUT I can read a dipstick, and those "dipsticks" will only be doing my warranty work from now on. If they mess up again, I'll be getting my warranty work done at another local dealership. I meant MAY not MY. Edit won't work now.That would also prevent the dealer disabling the dash cam by unplugging the power- like just happened to me.
(They must have been mad at me catching them out last month "mixing" my supplied 5.5l of oil with who knows what from a plastic jug. Idiots- the oil level doesn't have to be all the way to the top mark.)
