About a week ago I was driving home from work and I happened to get a blowout, I was about a half mile away from my house and I live on a soft dirt road so I drove the car home very slowly. When I arrived I installed the spare and noticed the abs light was illuminated, drove to get a new set of tires thinking the light was due to the spare being a different size than the 295 on the opposite rear side. Following the tire change the light remained illuminated, I drove home and attempted to clear the code with a generic obd scanner to no avail. I figured it needed a proper sds tool so I took off to my friends house who has my sds tool to reset the code. By the time I arrived after 50 min of driving the transmission started a small wine noise. We checked the codes and lo and behold it was the driver rear speed sensor, we replaced it with a new one and the light went off, as I left and got about .5 mile down the road the abs light came back on and the speedo died, by this point the transmission was making a loud wine and dropping to nutreal on acceleration, we replaced the sensor again With the same result, the scanner shows accurate wheel speed sensor data up until the speedo dies and the light reiluminates, no transmission faults where detected. I cleaned the ring that the sensor picks up on which temporarily fixed the problem for about 5 miles then the abs light came on and the speedo died again, the transmission seemed to be more forgiving during that period but still made the wine noise... what gives?? Has anyone experienced this before? 100k flat on the odometer

 

any updates ???
I have a 2009 c300 abs and esp inoperative my car has driven fine with these lights on from 2years ago and had a jerk when put the car in reverse and also when you in drive switching too reverse it took maybe 3 seconds too catch…..But one day I was driving a little fast as always just a lil test run every now and then but my belt broke I replaced the belt and noticed my power steering pump went out when I tried too drive it the wheel was hard too turn I made it down the road and then I came too a stop then started driving again but the car wouldn’t switch out of first gear and had a hard jerk going into reverse and drive the jerk is so hard it feels like someone hit you from behind so I took it too my Mercedes specialist guy he replaced the power steering pump and fixed the issue which is something with the abs the car drove bout an good 45 mins from the shop to my house perfectly til I put it in park and then went too put it in drive too go too the store and the hard jerks were back and back too being stuck in first gear then the belt broke again and then bust my radiator I sent the car back too the specialist he replaced everything and he test drove it and said it was ready and all good too go I had the car towed too me because I didn’t have a second driver so I backed the car off the tow truck it seemed fine I went from park too drive and the hard jerk came back and still stuck in first gear I’m currently sending the car back today because the specialist say the transmission is perfect and keeps saying the abs but I wonder if it’s something with the speed sensors actually because when I bought the car and the lights were on silly me but it drove smooth no leaks but the guy I bought it from did tell me the little jerk going into reverse and the 3 second switch from drive too reverse /abs and esp lights were on cause of the speed sensors needed too be replaced and he showed me on his scan tool….. Does anybody have answers too this problem yet???? I will update after this shop visit
and yes I do trust my foreign car specialist he really knows what he’s doing been doing business with him for years just my car hasn’t made it back too him yet
