Help! ABS, Brake, DSC, and Tire Pressure lights on after car wash?

[Mistere311]

Weird problem with my 2005 X5: About 4 miles after I left a automatic car wash (dumb, I know) the ABS, Brake, DSC and Tire Pressure lights all came on. The lights all popped at once while I was traveling about 40 MPH, didn't notice any mechanical issue or clunking from the truck. The Service Engine Soon light came on later. The instrument cluster (speedo/tach) working fine. ABS does not work, nor does traction control, but the truck otherwise seems fine.

The car wash was one on a track where one wheel is static and and the track pulls the car through while the other three wheels roll freely. The auto transmission was in neutral the whole time.

First thing I need was disconnect battery for 10 mins, reconnect, all lights on instantly after start up.

Second, I checked the SES light, the OBD2 code is P152B, which appears to be a speed sensor. After I clear the code, it will always come back up after a few miles of travel.

Third, I have inspected the physical connenctions on all, and they are solid and clean. However, I noticed the driver's front outer CV boot was torn and will need to be replaced, there was CV grease everywhere, though not near the speed sensor or its wire, or connector. It appears to have been torn for sometime.

Could the car wash really have caused all this havok or is it just coincidence I have these problems right after I went there?

I also have tried all the "turn the steering wheel lock to lock" etc. fixes I've seen via search, and nothing works.

I see a variety of options: Pay for a dealership diagnosis, throw speed sensors at it, or buy the ebay GT1 cable for 35.00 and tinker with the codes myself (have laptop for it and experienced in coding for VW days, think VAG-COM).

Any other bright ideas?
