Engine Fail Safe Prog+ABS light+DSC light+sluggish

[2003x5guy]

Replaced the Steering angle sensor, reprogrammed computer and all lights off and running good. Steering angle sensor is a DYI... Just need a screw driver, a small hammer and wrench.

Thanks. Where is located this sensor?

For my model, it is located in the steering column under the "knee area" dash trim

Was just driving along when warnings happened.

Details:
2003 x5 3 liter
I do not know the age of the battery.
It has been raining quite a bit around here (Tampa...Tropical Storm Isaac)

I looked up the warning message in the book: Paraphrase: Electrical engine fault, see dealership.

Thoughts? It seems to still be driveable but very sluggish acceleration. HELP! Thanks in advance.

In my case all the warnings lights were due to a faulty ABS module failure. Dealer was asking 1500eur for it, I could trace the original manufacter in Spain "Bosh" and manage to get it for 350eur.

I am kind of sh!tting myself that I am having a gbx issue coming on... I stood under the chassis last night in the lube shop as I had heard this 'clacking' noise when I shut the car off, like gears missing, happening since the weekend, and here's what the underside looked like; I got someone to shut the car off and the sound is definitely coming from the top of this unit.

Yup, either flip that gear, or buy a new one and swap it in there. Speedogears.com.

Well, put me down as a fully paid-up member of the 'stripped-gears club'- I didn't have the reverse Torx tool to pull the actuator off on Fri so I had to wait till my parts guys were open this morning - lucky I did as not only did they replace the plastic gear as if they had done the same thing many times before, but from the back office the boss happened to pull a very nicely machined BRASS gear which we swapped in. He gets them made up himself.
The really telling difference after this fix was the shifting using the tiptronic 'manual' - recently there was a long delay between pulling the gear shift and the actuator 'bumping' the car into the next gear, maybe one second where the revs carried on climbing before the change kicked in. This delay has completely gone, and the progression with Auto is once again very smooth. Plus all those annoying warning lights have gone off for good. Apparently the oil in the previous picture is from a busted oil seal under the exhaust side, so I need to see to that next.
Here's the nicely rutted plastic gear, the opposite side of the plastic gear (intact), and the new brass one we put in.
