I recently purchased a E46 320 CI SE from my brother-in-law he's had it for about 4 years. The car is a great colour (dark blue) and has the MV wheels which make the car look great! However there are a few problems with it;
1) the pdc doesn't work as I get the long beep and upon further inspection I had found that all 4 sensors click - I have found a great thread here and have asked for other troubleshooting assistance.
2) it has the cd player - not having owned any CDs for a number of years wanted to know whether it was possible to add an optical output or auxilary output to plug my generic mp3 player or will I have to buy a new head unit to allow this.
So far so good on the whole other than having to top up the oil as I don't think he's been monitoring this as much!
Looking forward to sharing my experiences and reading about other peoples issues on this forum!!!
