I bought this S500 cheap so of course it has issues. Just replaced both front wheel speed sensors. There were no sensors on the wheels?? Go figure..
I replaced the sensors over the issues of no ESP, no ABS, presafe not active, and cruise control not working. DTCs showed only the two sensors having fault. No other codes were present. After installing the sensors all warnings went away and cruise now works. That's nice but the ABS light remains on despite the fact that the ABS warning went away. I ran another scan under ESP and found no more wheel sensor codes but now a code for rotary speed and lateral acceleration sensor has a fault. This appeared after the sensors went on to the car.
I am asking 2 things. I want to know exactly where my sensor is located? I have looked for this info and find different locations from the trunk to inside the console and under the passenger seat. Seems that different models are different. My car is a 2004 w220 S500. Can someone that knows this car tell me where to look?
The second thing I am asking is if anyone can tell what they may know about this fault of ratary speed and lateral acceleration sensor? Is this why I still have the amber ABS light on?
thanks in advance for any advice, it will be appreciated. Bruce

Hey thanks for the link, it's a great tool. I am finding out a lot of stuff about this car though I still have not found the b24/15 sensor. I will continue to dig for it. It seems that the location is a highly guarded secret LOL. I have several hours in research using Google, YouTube, and forums, but no clear answer as to, where is it? The funny thing is I have found many articles that are quite clear as to where this part is located, but none are my S500. Each car it seams is in a different location, most are C class or ML a bunch are W128 and W211 for some reason? The scary part is most are located in the most impossible locations, the worst of which is under the carpet located under the passenger seat. Requires complete removal of your seat and then pulll up the carpet. None that I have found are just some place you are able to put your hands with out major dismantling of something. I'm used to that with Benz and normally don't mind. I like to complain about Benz engineers while digging my way to some strange place to put a relay, but I like to know where it is before I start tearing the car into pieces. I wish I could find someone that has changed this part on a 2004 S500 or knows clearly where is it? I will be definitely posting where it is when I some day get to mine. Thanks again for the link. I am now going back to it now to dig and search..

You need WIS and EPC. Google and the search button on this site will find it for you.

B24/15 is located under the left rear passenger seat cushion for model 220 with engines 112, 113, 137, 613 and 628 after June 2000. Per WIS GF42.45-P-4801-01C.

Well there it is, under the back seat, left side!
I now have a new one and will be replacing it when our weather warms.
Thanks for the help from all of you.
