I was wondering if people actually does some tricks to their mileage meter. I heard some people unplug the fuse and disable the mileage meter. Then the mileage of the car wont go up. Do people really do that to w203? I know people do it to their CLK.

I hope you know that's highly illegal, and I doubt it would be that easy on an MB, or at least the computer would know that you have done it. If someone has done it, they're surely not going to talk about it on here, and you probably shouldn't either. For MB's, it's more of an accomplishment to see how many miles you can make it last.

And also, if you call it a mileage meter, you're probably not qualified to work on it, so don't try it. It's an odometer.

Like stated above that is highly illegal and a federal offense at that. If caught that is some serious jail time and fines. Also it is stored in several places including the vehicles computers so getting it to not count on the odemeter will not stop it from counting. Another note is that it is most likely tied to the rest of the gauges to discourage it more, remove the fuse and the speedo most likely goes with it or maybe the whole dash. In the old days people disconnected the speed cable, so the speedo did not work and therefore no mile recorded. Now there are sensors that send that info to the Engine Controller, Transmission Controller and Odemeter(or the computer that controls it). Without that info the Benz may not even run right. Oh and did I mention that this is against the law and also highly immoral. Not to mention of all customers I would think that someone that could afford a Benz would not want to cheat like this. Maybe I am just to moral a guy.

this is almost laughable. i don't think that simply unplugging a fuse is gonna do anything except make the car mad.

mctwin2kman is correct. the Controller Area Network data exchange system inside Mercedes cars is very sophisticated and does not deal with data by simply acquiring it from the various sensors on the car and then displaying it. not to mention this system uses all fiber optic cables.

Ya... i totally agree... i know its illegal, i would never do that either. Just wanna to ask and know the answer to fill up my curiosity. Like u said, someone who can afford a MB shouldnt cheat like this. I just saw a post discussing about it and the site is not a U.S. site. I guess its from another country somewhere.

hi....u said u can do that on CLK?
how do you that?

btw BMW odometer can also be made not to count but i think the AC etc...will not work..

It's not gonna work. The mileage information is stored in both the Electronic Ignition Switch and the instrument cluster. The instrument cluster is linked to the engine compartment CAN and the interior CAN. Data are transferred over both bus systems and to almost all the control modules of the two bus systems. The only way to prevent your mileage from going up would be to disable every control module that is either on the engine CAN or interior CAN, at which point your car wouldn't do much of anything. Except maybe implode into a black hole........

Matt230K

mbtech, are you saying that even if you disconnected the instrument cluster and drove around, it would jump to the correct miles as soon as you plugged it back in, because it reads off the ignition switch?

mbtech208

That's correct. They are 2 separate systems, each one keeps track of mileage and compares it with the other. Plus, driving around with your instument cluster out would create a plethora of malfunctions and fault codes.

You could drive the car home backwords...that would bring the miles back down...

dude, do that anyway, it's a great movie.

Actually the corect way tp disable it is to unplug the speed sensor off of the tranny. That would disable it everywhere. Now I do not know if the Benz even uses a speed sensor off the tranny, most cars do as there really is no other way to accurately measure it off a wheel, since they at times can spin at diferent speeds. Not to mention when a rear wheel is spinning faster than the fronts the speedo should read the rear ones, which means it is measured off the tranny in most cases. I do not know what this would do to the computer or anything but it will not record miles and I am sure would throw a fault code or two.

On my 99 clk, I got a white gauge faced cluster from a w202 c class sport.

When I plugged in that cluster, the mielage changed from 19000 that my car had to 48000 that was on the white cluster. I didnt like that, I tried driving and everything workded fine and it registered miles. I then put my old cluster back in and no mileage increase was put on it.

All in all, who knows if it is stored somewhere else, but i wouldnt want to drive my car not knowing the mielage, so so long to the white gauge idea

Not anymore! Mileage is mileage in the eyes of a computer.

The tranny sensor only counts tail shaft rotations. It to subject to the same wheel spin problems. It is possible to collect vehicle speed from any of the ABS sensors and drive shaft.

Hmmm, interesting topic, but I don't think I need it. Last year I put 3,000 miles on my car. This year I am trying to be more aggressive, maybe 4,000 miles. At this pace, who cares about the mileage.
