Default TPMS sensor problem

I replaced my factory wheels and tires with new aftermarket ones. The price the seller quoted for new Mercedes TPMS sensors was expenses so I asked for an alternative. He had Mercedes 315Mhz TPMS sensors that he had removed from another SL550 and he offered them I agreed. The new tires and wheels are on but I can not get the TPMS sensoprs to hook up with the car. The error message is "Tire pressure monitor inoperative. No wheel sensors". I had a flat on one of the tires so I checked the TPMS when the tire was replaced and it is indeed a Mercedes unit at 315Mhz.

Does anyone know what I need to do to sync the sensors with the car? I looked in the owners manual but the instructions don't apply with the error message I get. Any suggestions?

I have a similar problem. 2007 CLS63, recently added 20" HRE's with tpms. For some reason my car is giving the "tire pressure monitor inoperative - no wheel sensors" error. Is there some kind of reset or menu function that will get the system back on line?

the sensors have to be the kind that the car came with. they are not interchangable and each rim is differnt so you could have an airleak at the valve stem and rim. you cant put a sensor from a cl on a c class, or ml on a sl. if they are the same origianl ones for the car thenmaybe its broken or the battery life is weak or at Zero in the sensor
