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.
