I did a search and came up empty on most my questions so here we go....all questions pertaining to a 2003 x5 3.0i

1. I read that pushing the arrow button on the keyfob opens all the windows and sunroof. This does not work on mine. If I put the key in the door and hold it to the left it does however. Did this not work on all models?

2. If I remove the rear canisters on the exhaust and just run straights from the main muffler to the rear, will it toss any codes? Has anybody done this? If so how did it sound?

3. If my model did not come with a subwoofer box in the rear are the connectors still present and can I tap into them?

4. (read about this but couldnt find the thread) In the morning and ONLY in the morning on initial movement, going from R to D it hesitates and slams into D unless I kick it over into manual.

I have more but I dont want to clutter. Any help is appreciated. Thank you
