Traction control not operative

[Hunterka84]

Hi, I have a Mercedes c220 2013 5 door, my traction control became inoperative along with run flat indicator and cruise control, I was told this would be a faulty abs sensor. I have replaced all 4 sensors but the issue still remains, the abs light on my dash is not illuminated so I presume the abs is fine, can anyone help?

Get the car on STAR and have the error codes read. Otherwise you are just guessing and guessing gets expensive!
Any changes made to the car just before the problems started?

Can’t remember it’s been a while since this occurred, it just happened out the blue
