All Activity Module for 2001 ML430

Hi my All Activity Module died which means my automatic car locks and alarm do not work. A new module at the dealer will cost me $1000. I have found used ones on Ebay but I am not sure what is involved in getting a used one installed -and if this is a good idea. Thought??

You need to contact the sellers on ebay to see what instructions come with the unit. There could be some programming functions that a MB dealer needs to do. Is the $1,000 quote just the part, or is installation included?

Parts I’ve bought on ebay have been OK.

You could do with the services of an automotive security and alarm specialist. Look in the Yellow Pages for one.
