I've a problem with a Ford Focus MK2 and looking for advice as I don't want to run into mad costs, here's a quick introduction on what happened:
- Battery went flat - as radio and lights were turn on for too long without engine turned on.
Car was jump started - it gained electric power back again, however it didn't start.
On ignition the lights on dashboard light up and it says 'Engine systems fault' and there's no error codes on OBD reader. Immobilizer is also rapidly flashing in red, then it starts giving a PATS code.
Just as a note on ignition something in the engine makes noise - but it doesn't sound like any mechanical component.
Are there any next steps I can take to solve the problem myself?
Looking forward hearing from you.
Thank you! Adam
