your right about the ASR lamp is lit up all the time and the system is not working = Spinning tires.
I would expect that to generate a fault code, but as you say, the faulty part needs to be feed with power to do so.

I will check later on the cornector where the plug from the EA goes to if there is power to bee messured 12 volt i guess.
The CD i got is temperaly gone in the mess hope i find it later.


I got the impresion that the EA was the electric device that pulls the throtle to rev the engine, but I see now that it might just be a general Headline for a complete system.
But what are the part then called that eletronic pulls the throtle???

Send me a PM w/email and I will jpg the EA to you and then you will know by the connectors and wiring to the 2 units if this is in fact the same system.
This will also give you the inner modules circuits/electronics for testing each section w/ohm meter.

My PM is stricly for data copy , such as schematic transfers.
I am on 8 different Forums and have no time for Private Diagnostics, so please adhere to this.

Hi again.

That is deffently what i needed great stuff to do diagnostic with.
I am an Elektronic technician so it is great to study.

But what i was more than impressed of,I was siting and seaching for some ASR on Google and I found a site that descriebes all the mercedes safety systems as the ABC, ABS, ASR, ASD, ESP, BAS and more, and it gives you all information about the system in box diagrams and technical explanations with part numbers and pictures, even small videos of haw and where the different stuff is located in different engine types and how to make diagnostic and test about the system and maintain it.

But as my laptop went dry for power and suddently powered down, I didenīt reach to save the site!?!?! and now I canīt find it again.
It is for sure realy realy good DIY stuff also for non technicians.

arhhhh haw can I find it again,,, anyone knows the site am talkng about?

anyway i havenīt got the time to day for a quick test or look at the car, but I will be back when i sort this ASR problem out, and find the very superior mercedes safety site again.
That site should be somewhere on this forum for everyone to find that wants great and detailed information about all the systems.
