After many BMWs, finally snagged my first X

[JesterMX6]

One step forward, two steps back.

Replaced the right ball joint (Huge PITA to do btw) and took care of the loose front end issues I was having so that's nice. Also changed the oil and filter. I'd been smelling coolant and seem to need about 20oz of fluid every fill up or so. Unfortunately pressurizing the system to almost 20psi yielded not a single leak so I'm not sure what's going on there. Bubbles in the system would explain the need to put some water in the system, but it doesn't explain why I smell it sometimes after parking.

Now the oil drain plug is leaking. New one and washer should be here tomorrow, along with a pair of fresh halo blubs.

Looked over the tail light and there's some decent scorch marks on the circuit board and the sockets. If i wiggle the socket around it makes a connection, so I may try cleaning it up instead of messing with LEDs.

FM reception is trash so i'm pretty sure i'm going to have to mess with the diversity box or whatever its called and see what's happening there. Still getting the following codes when driving:
P0134 - O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0300 - Random/Multiple Cylinder Misfire Detected
P0301 - Cyl 1 Misfire
P0302 - Cyl 2 Misfire
P0303 - Cyl 3 Misfire

Makes me think the O2 sensor just needs to be replaced. I hope that's all it needs.

Using an O ring around the DISA valve seemed to get rid of the lean condition code I was getting and brought my idle up about 100rpm.

Also found the intake boot wasn't sealing (even with the hose clamp cranked) around the MAF so I wrapped some tape around the maf to better mach the diameter of the boot. That brought my RPM up even more at idle and fixed the weird hesitation i was having. Problem is i'm still dropping idle after I've been driving for a bit, but i'm thinking its related to the O2 code.

Oh. Confirmed it needs rear pads now too.

The diversity reception unit needs power and has some connections related to the OEM radio. Since you have replaced the OEM radio, these connection may have been altered. Common complaint when the OEM radio is removed....

There's a ton of wiring variations; you can see them all on the newTIS.info web site...
