So went to drive the car around the block coz I havent driven it in a few weeks and right from the start its acting weird.

Car drives fine in reverse. If I go straight very slow....basically let it roll, the car will be fine. I mean I can give it very minimal throttle input but anything more than maybe five mph itll lock up the front wheels and the traction control light will flash.

Any ideas?

Nothing is jammin the wheels, everything looks normal.

Sounds like a speed sensor or ABS problem. Are your BAS/ESP lights illuminated on the dash?

Wondering if it could be a faulty emergency brake assistance

PJmak

Nope. Everything looks normal.

I read that it might be the steering angle sensor.

503C43 ////AMG

i don’t think the brakes engage with a steering angle sensor. It should also activate the ESP light. The fact that it is activating the brakes makes me think it is a speed sensor.

PJmak

It does activate the esp light as its locking up the wheels. I dont know why I wrote "nope" above sorry

if it is a sensor there will be a code.

Post #68 says wheel speed sensor. I think someone mentioned that earlier in this thread

PJmak

Where is this sensor located on a c43?

Have you scanned and pulled any codes?
Found this video which may give you some insight:

This was the cause of the issue. Replaced the part with a spare one I had and the issue is gone.
Thanks

Thanks to others for replying.

Awesome that was it.

And where is this module?

I think, this is called "turn rate YAW sensor",

it's a part of main (ESP & angle steering sensing system),,

it's in the trunk..
