dimsim 2 Report post Posted April 7, 2011 Hi, first time here pretty much and was hoping for some advice with my 1998 E46 328iA4. The car has a NZ dealer service history from new , now done 160ks and I was wondering if there was anything I should check/test at this age/mileage and also if you think its worthwhile purchasing mechanical insurance? I have a mate in the industry so can get the insurance for wholesale which saves a few hundred but is still just under $1k. I think its through the AA. I read in the Dog and Lemon guide that the transmissions were only built to last 150k's and as they were sealed it was a replacement job if anything went wrong. Does anyone have any experiecne with major faults on these? Are the cooling systems still a bit dodgy (leading to overheating, cracked heads etc) or is this model more immune from the earlier 3 series cooling issues? Any experience people have with one of these would be muchly appreciated. I am an ex BMW registered technician but havent been near the spanners for a couple of decades (but am looking forward to having a tinker once again Thanks Quote Share this post Link to post Share on other sites

The car has a temp gauge so best it gets used, all the time! The trans usually gives up the ghost around 200k mark, this can be avoided with regular servicing of the transmossion, (oil and filter), if this is done the trans will be sweet. The moral is, yes get a mechanical warrenty, expensive but it more than likely may be used. Quote Share this post Link to post Share on other sites

The trans still has a fill bung and a drain bung, remove the trans pan to access the filter. Quote Share this post Link to post Share on other sites

Thanks for clearing that up - from memory this was done every Inspection II service or 80k's is that about right? Quote Share this post Link to post Share on other sites
