Are Volkswagens in general prone to freaking out if the brakes are applied to a wheel that's in the air?
I'm working through a rather bizarre issue with my car after a series of upgrades. Not long ago I upgraded to Eibach Pro-Kit springs and 26/23 mm Eibach swaybars (both set to soft), struts are Koni Sports (Yellows). At the same time I installed Passat spindles and a subframe collar kit. I've also replaced the battery because the old one died.
As I've become more comfortable with the upgrades I've been driving the car more aggressively around corners and lately I've been getting an "explosion" of ABS, traction control, and red "brake" light flashing with associated loud beeping, followed shortly by the "airbag" light illuminating. I can shut off the car, start it again, and all the lights clear out.
I've tested traction control, XDS, and ABS systems independently before and after the error lights come up. Prior to the warning light explosion all systems function, after the lights come up they do not function.
What I noticed a few minutes ago was that the lights were coming on after aggressive low speed maneuvers, think autocross. A reliable way to duplicate the issue is around a nearby, slightly off camber traffic circle, and occasionally around 90 degree right hand turns. These are the kind of corners that cause most FWD cars to lift the inside rear tire when driven aggressively, and in the case of the 90 degree right hand corners it's possible that it's happening as I'm trailing the brakes to modulate load on the front tires.
I've ordered an OBDeleven so I can check codes and see what's going on with the wheel speed sensors, which I've already unplugged, removed, and cleaned. I also need to order a GoPro mount so I can see if I can tie the errors to lifting a tire.
Sorry if this is a well known issue and I never got the memo. I ran some searches and came up empty, mostly a lot of information about troubleshooting wheel speed sensors; which may still be my actual issue, but I won't know for sure until my OBDeleven arrives
