2006 Mercedes Benz S430 Base 8 Cyl 4.3L
Steering & Suspension
I replaced front wheel bearings,and seals
.Then test drove the car it had hesitation and 3 malfunction warnings came up on dash.the (ESP and brake assist and air ride)
I would say that it is required at this point to identify the numeric fault codes that are now stored for the abs which may also cause other systems to also turn the warning lights on. Example: an abs fault on most cars will also turn on a suspension control warning light if so equipped (in this case the light is for the Electronic Stability program or ESP) and definitely the traction control light, so I believe that your problem is directly related to the abs wheel speed sensors which may have become damaged during the wheel bearing repairs. Recheck your work, read fault codes. You will need a code reader that can access MB abs system.
