Default DCCD flashing, VDC & Hill assist lights on?!?!

Hey guys, I got myself a JDM 13:1 RHD steering rack, ALk and bushings (which i will give my impression later on). Installed by a very reputable workshop.

After the installation of the rack, the DCCD lights were flashing, VDC & hill assist lights were on.

Mechanic said most probably the steering angle sensor needed recalibration.

So i went to the dealership to get it checked out. They killed my warranty period because of the ALK i fitted (which was going to end in 3 months anyway)

Long story short, they said the switch combination is damaged and needed to be replaced. Part # 83113FG010

What is a switch combination? What does it do? I know its the piece that the wiper and lights switchgear attaches to. I think its also called steering wheel roller connector? As it shows in the invoice.

Prior to this, i had a curbing incident that left me with a bent LCA and curbed all 4 wheels. But There were no problems before the quick rack.

Could the installation have something to do with it? Let me hear your thoughts.

If you went to the dealer and they found out what was wrong why are you asking us? You go to a dealer, they find the fault, they fix it, you pay....that's how it's supposed to work. If you have questions, ask them as we are 17,000 miles away from you and have NO IDEA what the problem is or how to help.

actually it is a simple mistake that your installer made,they had the rack disconnected from the steering colum and turned the steering wheel to far,there is a spiral spring that went to far one way and broke,the spiral spring has wires in it for the air bag and angle sensor. i would try and get the install shop to cover the cost to repair,it is there fault.

Hey, I have the same problem after I installed a set of steering rack bushings and now all the same lights are flashing on my 08 sti. Aside from from some steering notchyness, I'm guessing I also broke the spiral spring with all the sensors in it. Is it safe to drive my car cautiously for a short period if this is in fact the problem?

Why would you change bushings on practicly brand new car? and no there is no problem driving it like that, the only thing is that your dccd in open all the way witch means you have more traction in the rear then in the front, unless you lose control of the vehicle it would be more like a 100% rear wheel drive. go to the dealer and sort it off

This is wrong. It always gives 41:59 torque split with an open DCCD.

oh yeah... take off hard with your dccd open all the way on a one way street when its snowing and let me know what you found out. or take a curve at 20mph so you can see what wrong really is.. and you guys are suppose to be the so called "specialist". do your homework buddy.

Actually the 08' has a spiral spring (clock spring) separate from the steering angle sensor. The steering angle sensor doesn't have anything inside of it to break like the spiral spring. There should be someway to calibrate the angle sensor........which i would love to know HOW!!

Um...he's right. The torque split is 41 front 59 rear. This cannot be over come as it is the mechnical limitation of power transfer that the center diff can perform. The 05+ sti can go from 50/50 to 41/59. It will lever send anymore power to the rear.

I am not sure what you mean here. Relative speed of wheels are not in any way indicating that you are getting 100% of torque to ones which spin quicker.
In 08 STI with an open DCCD you always get 41:59 split regardless of traction on any of the wheels. It still means that a car can power oversteer under some circumstances like you describe.
