      The P00B7 error code indicates low coolant flow, which may be due to a faulty thermostat, clogged radiator, or water pump issues. Audi A3 2.0 Turbo owners also note that after replacing the thermostat, it is sometimes necessary to bleed the cooling system to remove air pockets. It is worth checking the coolant level, the operation of the water pump, and the condition of the radiator. If the problem persists, diagnostics will help determine the exact cause.
