Hi guys,

I have an Audi A4 (B8) 2.0 Tfsi 155kW 2009 model. When I try to start it in the mornings, it doesn't want to start and it would keep showing me the following faults:-

• ESP Fault: see owner's manual
• Headlight range control defective!
• Alternate fault: Battery is not being charged
• Parking brake malfunction

While the "EPC" , "Check Engine" and the "ESP" amber lights stay illuminated on the cluster. After a few attempts of switching it ON and OFF while removing the key from the ignition..., the car will then eventually start.
This problem often also comes up while I am driving, and when it comes.., the car will shut itself down and refuses to start again, until after again a few attempts of switching it ON and OFF and removing the key from the ignition. Ever since this started, a lot of other things are no longer working..., i.e. central locking, opening/closing windows using the immobilizer. My main concern here is the fact that it shuts down in the middle of the road whilst driving in a lot of traffic, and that can be very dangerous because the steering wheel locks and the hand break (parking brake) will also refuse to engage.

What could be the problem??
