Thanks everyone. Feel welcome already! Not at work tomorrow so will have another poke around for a bluetooth number in the boot. I also noticed that while my drivers side door speakers don't often work - sometimes they do, and its both the driver and the tweeter cutting out at the same time. Going to pop the door off tomorrow to see if i can find a loose wire, failing that I guess the head unit needs to come out to see if anything is loose that end or possibly trace back a broken wire. If that all fails I assume it will be the head unit itself. fingers crossed that its not. Thanks also for the link to the user manual, when i'm next in the office I'll print it out - my little home printer will have a fit if I ask it to do that! Still love the sound of the exhaust, just wish it was a little louder at times. I saw a video on youtube of a 330ci that had the rear box removed and it sounded nice, not sure I would want to do that just yet as it may be a little too loud. Might see if I cna do the old golf tee trick.
