I need advice on how to reset the Brake Pad wear warning message on my 2003 c230 Kompressor sports sedan. I replaced all the rotors and pads on my c230 as well as the wear indicators now I get the pad wear message only when I shut the engine off and again when I start it ,the message no longer appears when I am driving,I think there should be a way to reset the warning system but I can not figure how to do it Thanks Willytac
Hi, Willy. You are likely to get more pointed information for your car if you post in the W203 forum as that is specific to your chassis; this general forum is less likely to yield exactly the answer you want. I have a W210 and on it once the wear indicators were replaced the malfunction warning went away. However, on one of them I failed to be very careful about the wire itself and vibration (I think against the caliper, I can't recall) wore through it and lit the light a couple months later. Replaced the sensor with a little more care and it's been fine ever since. MB usually doesn't change things drastically, but there are some newer models that require a reset through the star diagnostic system; again, that's probably something your fellow 203 owners will know.
Hello! I'm sorry I do not have an answer to your question, but I see you did your own replacement of your brakes and rotors, which leads me to believe you must know quite a bit about brakes. If you don't mind, I'd like to ask you a question. I have a 2007 C230 Sport Sedan which has about 25% left on front brakes and I have about 19,000 miles on the car and this will be my first time replacing the brakes. The service guy said most people wear out their brakes on this type of car within 10,000 - 15,000 miles. But, he said I will not only need pads, but I will need new rotors also. Do you know what the reason would be for this? What would ruin the rotors if I haven't even worn down the brake pads yet? Thank you for any help and answers!
Hi, Sheri. I'm with Len. MB uses fairly soft pads and rotors, and rotors do wear out faster than on other makes, but typically they are good for two and sometimes three sets of OEM pads. There are really only three reasons you ever are required to change rotors: damage (cracking for example), warping (you feel the pulse through the pedal) and that they have worn to their minimum thickness specification (or they are so close to it that they will have worn below that spec before the next set of pads are worn out).
If the "service guy" just told you this on a phone call and without a proper inspection, he's just looking to make extra money. Personally -- based SOLELY on that interaction -- I would take my business elsewhere, or perhaps if I was in a little meaner mood I'd ask him how he can say that without an inspection and then ask to speak to his manager.
Any competent Benz mechanic can change these, it doesn't have to be the dealer, and most metro areas in the country have at least one good indie shop. A good indie is invaluable if you're not going to DIY everything and don't have buckets of cash laying around to line the stealer's pockets.
Take care and enjoy the ride,
