I bought a new battery that ran flat after two weeks. Took it back to the garage and they disconnected negative from my battery whilst the engine was running to check my alternator but now I have brake light and ABS warning lights on the dash.
When I start the car they disappear as normal but reappear if I rev the car above about 1100 RPM.
He said the car was still fine to drive and they would disappear in a few miles but that has not happened and I have since read that a combination of these lights is an emergency and the car should not be driven.
Looking for potential cause of the fault.
I drive a 1999 Toyota Corolla.
