Seems like it will be a while before it all gets figured out.
Yep, who knows how long this is all gonna take.
In the meantime, my Jetta has a rear wheel bearing going out. The dash on our Jetta is lit up like a Christmas tree. Errors for the stability control, the ABS, the air bag, and the TPS system along with the noise from the bearing. I connected my laptop up to the Jetta via the VAGCOM cable that I have and the thing told me where the issues are coming from, right rear wheel. All of those systems rely on data from the speed sensor and the sensor reads the tire rotation from the bearing (I already replaced the sensor). I now have all the parts and tools I need to replace the bearing and I'll be doing that this weekend. It's going to be a bear since the axle bolt gets torqued to 150 lb-ft PLUS 180 degrees.
axle bolt
caliper to carrier (counterhold to keep from spinning) 35 NM REPLACE
caliper carrier (XZN 14 bolt) 90 NM plus 90 degrees. REPLACE
little screw/bolt that holds the disk on. 4 NM
rear axle bolt (XZN 18) 200 NM plus 180 degrees REPLACE
The axle bolt should be torqued to 200 NM and then the tire gets reinstalled, then remove the jack stands/jack so that the cars weight is on the tire. Then the bolt is tightened the additional 180 degrees. Of course the car will have to be jacked up again and the tire removed so that the new dust cap and the brake caliper can be reinstalled.
