Car you drive a car with the ecu removed?

No. ECU generally stands for Engine Control Unit, i.e. the brain or nerve centre for engine. Without it - no go. With that said, not all cars have an ECU. An older car with a carburetor, old-fashioned distributor and all that will run quite happily entirely without anything even remotely similar to an ECU. A Diesel car may not have an ECU etc etc.

How can you reset the ECU on a vw golf MK4?

To reset the ECU on a VW Golf MK4, you can disconnect the vehicle's battery by removing the negative terminal for about 15 minutes. This allows the ECU to reset and clear any stored codes. After reconnecting the battery, turn the ignition to the "on" position without starting the engine for a few seconds to allow the ECU to recalibrate. Alternatively, you can use an OBD-II scanner to clear any error codes, which also effectively resets the ECU.
