Dear Friends,

Unfortunately it is not the first time that I recal with an ASR problem in my 93 S500, what a terrible head ache with this car!!!

Well, but now the problem is different, because the ASR light comes on but the engine does not go into "limp mode".

I already gone to a dealer and the following DTC was taken:

ASR_DTC:30 CAN data line to electronic acelarator/cruise control/idle module N 4/1 - no comunication.

Does any one have an idea of what this can be? I realise since my latest problem with ASR that this can be related with almost any electrical component and not just from the ASR system.

By the way, I already replace the engine wiring harness, electronic throtle actuator, air mass sensor, rotors, caps, ignition cables, trans. switch, etc...

I hope you can give me a help!

Thanks in advance
