Hi guys and gals...

This is my first ever post so please bare with me if I do it incorrectly.

I recently taken my 2011 C Class Coupe out of storage after 3 years. I have since noticed a few issues have arisen.

1, The spare key no longer works, well the buttons don't work, as in they won't open the doors/boot but the key will start the engine. I have replaced the battery. My new local dealer wants to charge £189 to have 'a look' while its in for a airbag recall in Feb.

2, I'm getting 'device unavailable' while listening to DAB, probably every few minutes. Very annoying! The dealer seemed to know nothing about the fault although I seem to remember this happening before I put it in storage...again "we can run a diagnostic for you sir"

Any ideas?

Thanks in advance :)
