The AAM is a computer module that controls all electronic functions of the vehilce that are not related to the engine or transmission. Basically it is the MB term for a BCM (Body Control module)

Thanks a million Ron - Can you take a module from one ml500 and put it another . or is it specific to each vehicle. Mercedes wants to put a new one in at $1100.00 . Can I use a used one or can I buy one anywhere cheaper. The remote door locks are the only thing thats not working.

You probably can use one from a different vehicle, but it would have to be erased and programmed to your car; something only the dealer can do.

And they may not want to do that for you. If you decide to try one from another vehicle, contact a quality auto dismantler, and try and get one that has the Exact same options and accessories as yours. If you can do that, it may just work.

Something else to consider is in the last ten or so years many manufacturers have encoded the VIN number into their computers (modules) so if you plug in one from another car you may end up with a VIN mismatch code that may not be fixable.

I would recommend doing more research and contacting your MB dealer (or a shop that specializes in them) and discuss your options with them.

Unfortunately, It may be the only real way to fix our issue is to pay the $1100. Good luck,.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
