ESP - Fault Code 00778 - Steering Ang. Sensor

[mrGutWrench]

__. Ms. Laura Lee's '03 Jetta Wagon (the waggin') has a warning light for ESP on the speedo cluster. It's now been on steady for the past few days. Here's the VCDS readout:

Address 03: ABS Brakes Labels: 1C0-907-37x-ESP-F.lbl
Part No: 1C0 907 379 M
Component: ESP FRONT MK60 0102
Coding: 0019458
Shop #: WSC 01266 785 00200
1 Fault Found:
00778 - Steering Angle Sensor (G85)
014 - Defective

__. Has anyone seen this before? If so, did changing the Steering Angle Sensor fix the problem? Where is this sensor? Where are the connectors for this component (so I can do a little "wiggle the wire and see if that makes any difference" troubleshooting)?

__. Any other comments?

Thanks, MrG

You have to take the steering wheel and airbag off to get to it and inspect its wiring.

__. Thanks. The sensor itself is inside the steering hub? Any experience - is it usually the wiring or an actual failure of the sensor itself?

First thing I would do is look at the measuring block group 004 and turn the wheel from lock to lock. Do the readings change appropriately? Is it 0 degrees (plus or minues 2.5) with the wheels straight ahead?

__. Thanks, Glen. MzLL is off on a business trip today (somebody has got to pay the bills around here) and I'll run these checks when she gets back.

I'm throwing the same code. How did this turn out?

I would try recalibrate sensor first. Go on ross-tech and see how to do it.Click on info and you will see.

I had the sensor replaced at local VW mechanic. Took them no time and it fixed the problem. Only downfall is sensor was over $400.
