Hi. I got 2003 SL500 and I had fitted Brabus Monoblock VI 20 inch rims. My car was at the dealer getting front spoler repaited and they had damaged one of the front rims. When they were repaired the rim the RDK sensors stoped working. I had tried to resent them couple of times but without any luck. My dealer had taken the tire from the rim and cannot find the RDK sensors. My question is does anyone know the location of the RDK sensors and how do they look like (a picture will be perfect). I guess that the sensors must be replaced? Or do you have a better clue why they dont work. My dealer cannot find them although.Thanks!

 

do you mean the tire pressure monitor sensors? they are at the valve stems of the rim. you should have metal valve stems which are attached to the TPM sensor

 

Yes I mean the tire pressure sensors. They are not at the valve stems as I had checked. Also I have Brabus wheels! Someone told me the sensors are inside the front bumper? Do you know if this is the case?

 

I had found out what was the problem. The tire pressure sensor in brabus wheels is not exactly oposite the valvle entry. You need to take off the tire completely to see the pressure sensor. It was missing. I guess when the wheel were repainted the guys forgot to put it back. I had ordered a new one now and waiting for the delivery. Hopefully my problems will finish soon.
