Hello all. I recently replaced the battery in my 55 plate Leon mk1 as winter finally got the better of it. It appears that disconnecting the old battery in order to replace it has caused the car's stereo to go into secure mode. I've leafed through the manual and it advises I need to enter the car's 4 digit security code. However there's no code written or printed on the stereo security card inside the manual. Any ideas how I might be able to reset this without needing to pay a dealer an extortionate amount?! Many thanks in advance.
 
I have BMW 7 Series 760Li Petrol car, and its battery goes dead. Then i ordered online for new car battery from Batterybhai.com. Their service team came to my home and replace the battery. They bring service battery with us, first they connect service battery because electronic system remain same and not need to reset. Then they takeout old battery and install new battery. I'm very happy and my car electronic system still same as before.
