My radio stopped working the next day after I had a tune up and some fixture on my car from the dealership. It says cdc hardware error and I am not able to remove my cd's from it. What's your advice or suggestion to fix or replace it? Thanks in advance for your assistance, I really miss listening to my songs in the car when traveling with baby, it helps us both to get by with time on long journeys.

Take it back to where the work was done. Most likely they had to disconnect the battery during the service. VW has a lot of tricks built in to make you go back to the dealership. There may be a code that has to be entered to unlock the radio.

I no longer live nearby where I got the service done. What do you suggest I do now? Should I try disconnecting the battery again? Not sure what to do.

NO! One of the dastardly tricks involves disconnecting the battery, even for people who simply want to replace it. There are experts who will argue with me, but I've heard too many horror stories about numerous computers locking up. A couple of mechanics said if the engine would start after the service work was done, it wouldn't come up off idle when pressing the accelerator, and it wouldn't come out of "park". The cars had to be skidded off the hoists and onto flatbed trucks for trips to the VW dealer to have the computers unlocked. Designing cars like that is not in the owners' best interest. In my opinion it is a "customer-unfriendly" business practice that makes money for the dealers. GM, BMW, and I believe Audi do similar things.

This information comes from a very high-level trainer who owns a shop that specializes in the one out of a hundred cars that no one seems to be able to diagnose. His customers are other shops around Chicago. He works with representatives from most manufacturers, and other instructors, then puts classes together to cover things like this and other types of diagnostic problems for mechanics from independent shops. If his information was wrong, someone would have corrected him by now.

To be safe, never disconnect the battery, and if you need to replace it, use some type of memory saver device. Some plug into the cigarette lighter socket and use a 9-volt transistor battery, but those only work on cars where the lighter always will work with the ignition switch turned off. I use a small battery charger with the leads connected to the engine block and the battery positive cable, but doing it that way runs the risk of a clamp popping off or the positive cable accidentally touching ground. Just have to be careful doing it that way.
