Apparently some late ones can be programmed but most need a different siren fitted which is a £70 part

think i can live without chirps for now but i will most likely have a natter to you at the kent gtg, look forward to seeing you and all the others there

Don't 3 and 5 need other bits?

Are parts required for the tyre pressure option?
Don't think I can make the 11th

I dont think so because the ESP monitors amongst other things the diametre of the wheel and the revolutions of it to monitor any slip and that how it knows the tyres going down. It doesnt actively display tyre pressure but tells you when you are getting a flat hopefully before you have a moment or knacker the tyre.

Shame you cant make it.

... It doesnt actively display tyre pressure but tells you when you are getting a flat hopefully before you have a moment of knacker the tyre.

On all the W203s the warning message appears on the cluster when you have a flat tyre as the ECU detects the sudden loss/decrease of air pressure from the wheels rotating.

If going for the tyre pressure montior option then everytime air is added to the tyres the system has to be reset from the menu.

so i already have puncture warnings but I don't have tyre pressure readings? Tyre pressure readings could be modded in but need resetting at each pump-up?

Yes - The system has to be updated/reset from the menu everytime the tyre pressure is changed i.e. topup

I dont do these myself so I dont know. But my understanding of my car is that if tyre pressure loss isnt on your car's menu then it wont display if you get a flat because your menu wont have any thing to display. The whole point is that all the cars have the functionality but not all cars have the system activated, just like active cornering lights, they may be present but if they are not activated they wont come on. My car is 2005 model and doesnt have tyre pressure loss on the display (Just as an aside I'm not 100% mine will be able to have it activated either)

Miro will know as he does them all the time.

On face lfit cars such as yours and Blassbergs the tyre pressure monitor can be activated from via STAR... your cars will be ok! Once STAR has done the correct settings then on the MENU (Dash/Cluster) you will have the tyre pressure sub menu etc.

On every W203 if you have a flat then you will just get the error message telling you which wheel, like for example, similar to the error message of a "bulb failure..."

I hope you are right, but I'm told that on Star my car doesnt have the even the option to activate in the cluster menu

I'm pretty sure and quite certain that your car is fine for this mod - I will double check with the Technician that I know for you. I might need your VIN/Chassis details and will let you know.

I'm having the same prob with tank capacity on mine. Its really annoying because my friend did all the ods on an E Class yesterday! Why do my own menus have to differ!

Doesn't tyre pressure monitoring require a sensor in each wheel, a module in each wheel arch and a module in the engine bay/fusebox? It does on the E55 among others.

On facelift W203s "YES"- sensors/parts are rquired BUT on the Face Lift cars its different and STAR can do it just via the "Settings"- I am going to look into this and will get back with my findings...

I am confident when I say that there is no way the software could tell you tyre pressure or temperature without having a sensor, it could possibly detect a problem with a wheel through ESP and disengage cruise control etc but how it could decide that it had anything to do with tyre pressure I don't know.

TPM is a mod I hope to do to my own car, it was available on the W210 E55 AMG only but it is possible the CLK55 instrument cluster can handle it, if it does then I'm sorted

 

[blassberg]

thanks for your all your input guys - this is great.

R2D2 I would like the tank capacity mod too if you can get it to work on 06W203

Rite Guys....

The Face Lift Cars have "sensors" fitted as standard to the ESP system to monitor the loss of tyre pressure BUT will NOT display the tyre pressure level (this is a fact). So, my theory is that the sensors are already there for the TPMS option...

My other assumption is then that STAR is just needed to programme the car to then displaly TPMS. I will confirm this later for sure.... The same applies to the cornering lights mod.

Getting tank capacity to display can easily be done to the face lift cars.

Update:

PTMS: STAR can make the MENU setting come up and create the sub Menus etc. but cannot get the PSI to display (there may possibly be a way around it but Technician I know is not sure at the moment). He can set the MENU to display “Tyre Monitoring Active” – RESET option or something after filling the tyres with air… (not a definite 100% successful mod…).

Cornering Lights/Fog Lamp Indicator: Straight forward mod to do on Face Lift cars

Auto Lock Folding Mirrors – As long as car was built from mid 2003 and onwards very straight forward to do if it has the updated Front SAM Unit.

Tank Range: Straight forward to do and can be done on pre facelift cars too with updated Front SAM Module from mid 2003…

Alarm Chirp: Be done to any W203 via the Rear SAM Unit

It transpires now that PMTS does have some glitcthes in showing the actual PSI reading level of the tyres...

I still don't understand how it can work out the pressure without requiring a sensor inside the wheel to measure it, it takes more than rolling diameter to work out tyre pressure

Well done Flash. Do you mean tank range (which mine already shows or tank capacity which it doesnt. If you mean Tank Capacity, do you know what menu it is in on Star??

I'm setting of to the garage shortly so I might et a shot on Star if I'm fortunate!
