By all means ask them, but remember that the Dealer will charge you simply for looking for a code whether it is right or wrong (If they can actually be bothered to look!), and I do know of quite a few dealers who will charge and then make up a number, just to get your money.
But please bear in mind that any Code held on record from the Main Dealer will only ever relate to the Radio that was first fitted to your car when it was manufactured. As with the majority of cars, the Radio will have probably been changed several times without your knowledge. Whether upgraded from the original forecourt sale, upon delivery, within the warranty period, or when the used car salesman gets hold of it. The chances of your Radio being the original one it came down the production line with are very remote. So if you Main Dealer asks you for a Chassis number of the car, and not of the Radio, you can be sure this isn`t going to work.
When the Dealer supplied Code doesn`t work, they will often refer you to ourselves, or may offer to send it away to have it Decoded, so why not cut out the middle man, save a few quid, and deal with us direct. After all, where do you think the Main Dealer is sending it to?
