How much is it...

How much is it to ask? is it refundable if the issue is not fix?

Mechanic's Assistant: What is the model/year of your Mercedes?

2004 sl55 amg

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Yes. I had a flat tire with no warning. find out no TPMS. installed new TPMS (AMERICA'S Tire just like my 2003 sl500 and it works) but can't find or set tire's sensor. seems to me last owner had it deactivate. I hooked my scanner and can read every tpms on that matches the serial number of each tpms and tell me I have low air and I did have a low air. is that dealer need to activate?

Mechanic's Assistant: Have you checked your tire pressure? Do you have a tire gauge?

Yes I have set it to normal air pressure

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

If I have the dealer wiped all my software and reinstall it, would the tpms will be program back? since it will be cheaper for just to reinstall the software?

May I have your vin to check to see if your model was equipped with tpms?

also what kind of scanner do you have?

I'm using icarsoft. It reads all my tpms w/ serial number, tells me fault for low air on front left and sudden air pressure change rear right. In short I know my reciever works I just can't reset it. Did all the step but can't find where to reset tpms on cluster. Looks like previous owner deactivate it.

ok thanks, ***** ***** check the vin, if you can read sensors than you have it,ill check anyways but im certain you do if not you wouldnt be able to lol

give me a few moments.

I believed it's standard cause I used to have 03 now I got 04

ok yes you do have option 475 tpms high line

to see if you have the reset use the menu buttons on the left side of the dash,

the squares select forward or back in different menu screens and the arrows move up and down pages in the menu screens.

and yes it was standard for a few years due to federal law.

let me see which page exactly the reset should be in.

Ask Your Own Mercedes Question

ok on the home screen where it shows the odometer and the speed or outside temp just press the up arrow to cycle through and it should show the tpms and also the service due time or mileage and also oil level check. if you dont see the tpms then someone did recode the cluster to show NO tpms, if that is the case all a dealer needs to do is go back into the cluster and switch it back to yes.

Lou

the icarsoft is a great scanner but the one thing it lacks is the ability to code and change setting or activate things :(

What scanner should I get? So I can do it myself
Ask Your Own Mercedes Question
Customer reply replied 3 months ago
That's guaranteed to reactivate my tpms? Plug and play ? Rodeo for the suspension? MB only and no other cars? I was checking on it and just glanced on it says no software
Customer reply replied 3 months ago
Btw...is the unit get updated for the newer MB models? If I want to wipe all my software on my SL can I reload the original software for it using the unit you recommended?

let me address those

Ask Your Own Mercedes Question

yes that scanner is the exact thing we use in the dealer.

yes plug and play

yes rodeo, EVERYTHING the dealer can do with the exception of updating software because you need access to mercedes servers and i think that company can help you with that on a as needed basis.

read it thoroughly it does come with the software.

for updates you would need to purchase the newer cds as they come available from this company.

you cannot wipe any software and reload, that is not a function anyone can perform that i am aware of, there is a difference in the coding i am speaking of and the software. with the scanner you can add and change options in modules. never have we needed to wipe any software, the only time that is done is when we updated modules,. so the scanner has the capability of updating software but you wouldnt have access to the servers to perform this without contacting the company.

hope that answers that.

If I take my car to the dealer and tell them to wipe old software and reinstall with newer update...would the tpms will reactivate?

it doesnt work that way

Ask Your Own Mercedes Question

not with the instrument cluster. in your year there were no software updates.

it really didnt start getting crazy with update-able software until 2006 ish and not all modules. now in the cars every module is update-able.

the only thing they can do is go to coding and change the tpms coding to yes.

but they have to make sure they change the right code or else you will still have issues.

Ask Your Own Mercedes Question
Customer reply replied 3 months ago
The unit I'm about to get will give all the code I need or just plug and play that I plug it in and just reactivate or put yes or no along whatever the issue maybe

yes, this scanner will allow you to do that.

it is as easy as setting up settings on your phone lol

i can walk you through it as well.

here is a video i made.

https://www.youtube.com/watch?v=hOrkG0FYVDo&t=239s

it will show you how easy it is to navigate the modules.

when the time comes i can walk you through the coding as well.

Decided not to buy one. Went to MB authorized shop got the tpms activated where I can actually see the menu. Problem is the flat tire symbol won't show. Remove cluster if I can see if light are burned but I can't tear it down more before I cost more damage. The number on the cluster is the actual pressure? Going home from the shop a warning something like tpms inactive. What's that mean?
Did the symbol ever light up when you just turned the key on ? When the cluster performs its bulb check?
Ask Your Own Mercedes Question
Customer reply replied 3 months ago
Everything came on except the flat tire symbol. Was it done right?
I have to check to see if we use a tire symbol in usa in this model. The fact that you see tire pressures means its working , i can tell you the tire pressure is way too high, for your model it should be like 26/28 or close but i know its in the 20’s . The sticker on the fuel door or door jamb is what we set them to.
Ask Your Own Mercedes Question
Correct looks like you are close to the sticker pressures. 5psi higher or lower and it will say to check pressures. Pressure will increase with tire temp and outside temp and decrease just the same.
Ask Your Own Mercedes Question
Customer reply replied 3 months ago
How about the flat tire symbol not showing
I will have to check the owners manual and the mercedes wis to see if its on this model. I cant remember if it is or not. Pretty sure all models had it but i want to see it in writing. I wont be a ke to do that until the morning
Ask Your Own Mercedes Question
Just found a pic in the owners manual and there is No small icon for the tire monitor. It will show up in the left digital display as well as the right when there is a pressure issue . If you want to test this and have access to a air compressor, lower one wheel more then 5psi and drive it and the warning should come on.
Ask Your Own Mercedes Question
Customer reply replied 3 months ago
Can you check the engine symbol too? For the spark plug, what type of plug you recommend?
There is no engine symbom just says check engine and for the spark plug i recommend you go get them from the dealer. The aftermarket ones are not made as well as the oem ones with the benz symbol on them

Oh ok. Is it true that if i change the transmission fluid and filter MB star tool has to be connected to reset the memory?
My man, i feel i am being taken advantage of now .
No there is no reason to reset the oil life counter. There is a oil life counter but we were never told why and it has never caused a issue. I would be shocked if any newer tech even knew what you meant by that lol. I am including a screen shot of what you will see in the dash for a tpms warning .

Don't worry bro I got you...I'm talking about transmission fluid not engine oil.

Gave you 50%. On the transmission fluid change it's a BS to be reset? I was told computer keep the memory how the pressure and ho w I used it heavy or not. Thanks bro
Appreciate it man! So what you are talking about is our trans adaptation. We only do that when there is a shift complaint or a part inside the trans is replaced. Otherwise we dont mess with it
Ask Your Own Mercedes Question
Customer reply replied 3 months ago
I see cause I have a 2003 sl500 before and changed fluid, conductor plate and plug adapter due to limp mode. After that take awhile to shift back. Changing conductor plate should have it reset?
Ahh so in order to get out of limp mode you need a scanner that can read the trans module to reset the fault code or else limp mode will keep happening. But no for the conductor plate you dont have to reset adaptations. Only when replacing the valve body and or internal trans parts like clutches and drums .
