New to this but I'm desperate for help.
My 01 A3 will not start because the immobiliser kicks in. I have to disconnect the battery to reset it and then the car will start. I have just replaced a faulty cantral locking pump hoping that it would solve the problem but it hasn't. Another problem is that my drivers door lock will now lock all the doors but it will not unlock them. Also the engine management symbol on my dash is flashing constantly. Any advice would be great. I really don't want to go to dealers.
