So i bought a set of tsw nurburging 18" staggered 8.5 front and 10.5 rear. i put them on drove around for like a week and then i went over a pot hole and realized that my slip/abs/brake/tcs off light are on the dash. i took it to the dealer they said it was the wheels so i took of the wheels and put my stock wheels on then the problem didn't resolve i took it back to the dealer they said my abs actuators bad i took it to one of of my mechanics and he put the actuator in for me the lights went away. i drove about 100 miles and all the lights kicked back on but this time another light came on this time the engine service soon light came on including the other 4 do anyone know what my problem is?? i have enough brake fluid, rotors and brake pads are fine why is this happening ? I've been without a car for almost a month really stressing me out.

 

If SES is on, what's the code?

 

Not sure bro just dropped it of at the mechanic ill find out tomorrow, but i feel like these people don't know what their doing. they told me to change the actuator which is $1300 and the car is still not fixed

 

You could have just borrowed an obd scanner from an autoparts store and checked the code yourself. Also, is your alignment off at all? Does it make an noise when you turn the wheel? I had a similar problem happen to me and I found that it was the steering knuckle ball joints. Had them replaced and the lights went away.

 

Yea actually my steering wheel is off just a little bit and it does make that noise when i turn the wheel...but another problem i noticed today is that my speedometer and my trip gauge isn't working, tried connecting to the computer to check the code and the mechanic said that the computer isn't communicating. Is this because the abs actuator need to be reprogrammed for my car?

 

Steering wheel being off can cause some false problems. Steering angle sensor tells the computer that your wheel is turned when in fact it is straight ahead. Thinking the steering is turned, the computer expects the rotation of the 4 wheels to be different as in the car is going through a turn. Not seeing that triggers the TCS/VDC/ABS failure.

 

So you think with an alignment I should be ok??

 

I'd say lift the car first, and check the ball joint for rips or tears. It's really easy! Even the slightest rip, tear, or wearing can cause the lube/oil to seep out and mess with the sensor and cause bad alignment and some noise when you turn the wheel. Check out this link:

It's a bit of a read but it's full of info. Really helped me out and I ended up saving close to 900$!

 

Speedo not working , sounds like a wheel speed senser just died. Speed is measured off the rear wheels.
