before i go and jack up my '93 525i touring i thought i'd ask if anyone knows the location of the O2 sensor. I have the bentley manual but the conveniently left out the location on the '93 models. thanks in advance! Oh yeah, Im a fairly inexperienced mechanic (mostly maintenance and minor body work). I found a great deal on a full set of Bilstein shocks. should I leave this job to a pro? I also don't know if I have the self leveling shocks or not. anyway to easily find out? I've searched around but it's hard to find info about the touring models.
I don't know where yours is specifically, but it'll be hooked into the downpipes somewhere - http://www.realoem.com/bmw/showparts.do?model=HJ63&mospid=47414&btnr=18_0172&hg=18&fg=10 you might want to start over on realoem.com and pick the corrrect production month for your car. The diagram makes it look like it threads in above the cat - You might be able to replace the rear shocks yourself, but even if you tackle the fronts, the car probably should get an alignment afterwards. I personally don't like messing around w/ spring compressors, but if you want to get ambitious, I imagine the Bentley manual should guide you through it. Look through the realoem suspension pages, see what it shows about parts for the self leveling system. Again, not something I have experience with, but if your car does have that, looking at realoem might show a reservoir or some other self-levelling specific part that you can see if your car has it.
