Q&A

Have no intention of relying on autozone but when I purchased my fuses there after explaining my fuses burnt out twice quickly, they offered to use their diagnostic machine for free for whatever help it might be. They offered no advice other than what their machine indicated was the code. I am learning the code seems to mean nothing as it relates to my 1999 500sl. I will seek qualified help but it seemed a code might point me and the mechanic in the right direction as to why two fuses burn out so quickly. Guess I am expecting too much

yes and there code may not be correct. i believe that there code reader is ok for the basic cars but as far as german or swedish not so much.iv never seen a code come up that pertain to a direct short.

Interesting. I will take a closer look at value of the fuses. But still wonder why it is that foreign manufacturers )or any domestic ones for that meatter0 need do hide useful details of their specific codes from simple and readily available diagnosttic tools available in the marketplace (why do we need to beat up on autozone?) rather than keep secrets only they can decipher. Is that somehow a necessity or simply a way to maintain control of higher priced services?

They are not 'hiding it', it is just in a system other than the OBDII , which is for emissions controls and federally mandated. If you have a Benz dealer near you , you might check out their parts dept. I like to call it fishing , but I let the parts counterperson know that ahead of time , lots of parts people like to help out the retail customers when they can , just don't treat them like idiots or like they owe it to you to give up the info. Parts people can be your best friend or your worst nightmare. If what your experiencing in your car is a known problem they would be most likely to know , since they would be selling the parts to fix it.Good luck. If we can be of anymore help I'm sure someone else might chime in with some additional ideas.
