Tire Pressure Monitor

[cl55 amg]

Looking at the spec on my car (cl55 2001) it should have tire monitors. However it does not come up on the command system it rotates from service-oil-mileage.

Is there a way to see if its there? and to try and get working.

Should it come up on the COMAND?

We have Tyre pressure monitoring on our E-class but it certainly does not come up on COMAND

Sorry my mistake not on the COMMAND, I mean't on the steering wheel controls.

Is it a cost option for the CL and if you are certain it is fitted then there should be transmitters on each wheel.

If you cannot cycle through the commands and see the tyre pressure monitoring then perhaps it is not fitted?

Have the wheels been replaced or refurbished? Thinking asI am typing, if that were the case then I would expect fault messages

Hi,
I believe there are 2 versions of this.
There is a version that is hardware based and relies on sensors within each wheel that monitors and transmits the pressure to the car.

then there is the cheaper version, as in my 209, which is a function of the ABS or ESP and monitors the wheel speed and notifies any major changes.

The former is a fairly significant retrofit, whilst the latter, on most recent cars, is available via Star coding.

When I got a puncture it worked fine for me. Good enough IMHO

Agreed, ours is the optional, excellent pressure monitoring. First vehicle we haveowned in years that has had even tyre wear ,

Asking my wife to check tyre pressureswasnot the best use of my time, but with tyre pressure monitoring I now have peace of mind

Going back on topic, as soon as you turn on the ignition, you shouldbe able to scroll through the different features on the multi-function steering wheel. The tyre pressure system is an option and should jump out at you

Why do you think it is a feature?

That's what I thought it just doesn't show on the multi-function. It shows up as a extra fitted on the Russian site. The car does have aftermarket alloys and I did not see any monitors on the wheels when I changed the tyres, but as you stated would of expected some error codes.....

Someone must have disabled the monitor (instead of fixing it at some point). You could check if you have the control unit present, or the plug at least.

I would not trust the Russian site, do you have the original documentation?

My first thoughts were someone changed the wheels, but would we expect to see error messages.

The Russian site is just a guide but the original documentation will put your mind at rest as it lists all options that are fitted

I've never seen a difference with option codes from the Russian site when comparing MB on-line content. The option code descriptions are not accurate but that is another issue.

There would be a malfunction message at the cluster if wheels without sensors were installed.

If you want to check, just PM your VIN to someone at the forum who would loop up the data from EPC.

I have seen any number of errors. Some minor, but some very significant.

The most common error is calling an Avantgarde an Elegance.. That is a big error, but very common.

Lights, is also another very common error where halogenare listed when the vehicle has bi-xenons.. The list is as endless as the errors, but I am NOT saying it is wrong in this instance, but I am definitely saying it would be foolish to rely on it

My SL isn't on the Russian site at all.
