Hi, I've just changed the battery in my 2004 S-Type. I thought it was going to be straightforward but it wasn't and I need help. I installed a brand new battery and that went well. Then I switch on the ignition and two things happened - 1) the radio asked for a code, and 2) the low fuel light remained on and the display said 'apply parkbrake'. 1) I entered the radio code and was asked to 'please wait'. That was 5 hours ago! 2) When I apply the electronic handbrake, the low fuel light goes out and I get the total mileage readout! The handbrake remains ON no matter what I do, so I can't drive the car at all! I have tried disconnecting the battery and trying again, but nothing works, I get the same thing. Any ideas? I'm really stuck. (Btw, there were no problems like this before I changed the battery).
