pairs

Hi, up until yesterday the Bluetooth telephony in my 58 W211 worked fine. Now my phone can longer find the cars bluetooth, even though the command system says ready. Does this mean the Bluetooth module is knackered? If so are they easy to replace? I have no idea where it is. Cheers in advance

just had my c200 fly through the NCT with no problems :) did advise however that my rear driver side spring is corroded and may need replacing soon so...... do i replace one or a pair? im guessing a pair, great excuse to lower this bad boy

Does anyone know offiically what the procedure for replacing tyres on an ML is? Can I do them in pairs or do I have to do all four. Seems harsh to replace four when only one is damaged. any advice greatly appreciated.
