I have a mildly modded 2003 MCS and my Engine light along with my ABS , chk tire light and traction controll light have been coming on lately then going off a bit later.. With my Chk engine light it will come on about 2 min into my drive and stay on from anywhere between 10 min to a day then go off if i stop and get out for any length of time and start her back up. As for the ABS light it comes on with 2 others at the same time so all 3 are lit and then the tire light will go off then come back on it usually comes on when I make a turn all 3 will stay lit for a while then randomly they will go off. But I`ve been noticing something with my brakes lately . In the morning my brake pedal will shudder violently and sink at the same time kinda scary when you gotta stop . It happens at almost any speed more at a low speed like 5-10 mph any help WILL be greatly Appreciated
Thanks in advance Bryan H.

 

We have an 06 MCSC that had a similar warning light problem under warranty. They had to replace the sensors (2). I believe they said front left and back right? could be wrong on that, hopefully a tech head will weigh in with a better answer. Don't know if this would affect the brakes, I do know that the sensors are tied into the ABS system.

Hope this helps.

It sounds like at least one of your speed sensors has failed. When this happens, you lose the ABS in that axle which may account for the feel of the brakes.

 

Thanks yall I`m trying to learn and do everything on my own minus pulling the engine the only repair shop around here is ,Wicked expensive but i would rather pay out the A$$ than bring it to Brian Harris Mini service dept .Those guys are about the best Mini Killers out there. You can get info here that would make them second guess and Guess is what they do best
