Hi freind's, please i need help to remove the START ERROR from Mercedes A Class year 2000, ecu is BOSCH

its a bit difficult to say what to do...because it can be everything... like transponder is lost... or the coil has no contact and so dont read the transponder.. or the dump in the immo or ecu can be wrong.. did you do a shorttest of the car?

please post more info so we can help

yes and there is no fault code stored, the prob begin when the battery was dead for 2 days, and when we have change it this prob appears, it's only battery prob

i had same problem on sprinter... the car had bad bettery and then appeared star error.. i used a programm to repair the start error 1.3 that i downloaded here.. and the car worked.. but before i looked for the values of the immo and the ECU acourding to the autorisation.. and those values were very weared..

the car saw the trasponder.. and accepted it.. but the ECU and IMMO did not comunicate with each other...

so i checked the can bus.. beetween them.. and it was ok.. so the only possiblity was in my case that dump is not ok..

if i were you i would check first the values if immo and ecu .. to see what is the problem.. the errors in the shorttest seldom gives you good help..
