Mercedes Mechanic: Mike, Technician replied 8 years ago
Hi again..... Okay I have been looking at all these codes for you ...

They are quite an array covering all the systems of the car!

What I would honestly suggest you do here - is have someone connect the code reader on to the car -- clear down the ecu ( computer) ie, clear out all those fault codes - and then re run the car around for a day or so.

Then have the codes read again... Theres a very good chance that most of them will stay gone ...and that is what should happen.

If that doesn't happen and they all come back - then I feel its likely that you have a faulty ecu ...and the next best step would be to send that off to be tested / repaired. There are companies that do these tests / repairs as needed such as the Network 500 machine test work machines or others -- if you need a contact number I can give you one -- but do the procedure as above first.

Its certainly not normal for an ecu to have all these codes in it and it does point toward either system wide failure ( which is not at all likely ) or someone disconnecting all the wiring etc while the ecu is powered ( again, not likely ) or a faulty ecu and / or wiring - you should check the wiring loom specifically and carefully ...

Then if all is found to be ok - and you have the codes coming back as mentioned - have the ecu sent off and tested -- That has to be the next step for you on this one. And if it proves to be faulty - that would definitely affect the running of the car too...

So thats the way forward on this one... Let me know how you get on..and if you need that contact number for ecu testing..

Best Rgds.. MIKE

Hi again -- I agree with you -- it would seem somewhat catastrophic !!

Can I just check where abouts you live roughly - just so I get the right number for you ...
