W212 Disc Change - ABS & ESP Lights Now on

[Brianoc]

Hi,

I just changed the front rotors and pads on my 2010 E350 Diesel Sport (265) - Very straightforward BUT, when I started up and moved off the ESP and ABS lights came on and the dash is also saying the Run Flat Indicator is inoperative.

I've read somewhere else that this could be the sensor ring which is embedded in the bearing seal - Is this correct ?? I did pull the hub off whilst having an idiot moment as I haven't done the change on a Merc before but reassembled and set the bearing pressures as recommended..Possibly disturbed the seal as I did this I guess and possibly caused the problem

Anyone got any thoughts/fixes before I rip it apart again ??

Cheers

Brian
