2005 Sprinter won't start

Hello & Welcome to


Your words under 'already tried'...... "Vehicle will try to start ,but won't even turn over" are somewhat contradictory -- but I think I know what you mean ;))


The problem you describe though is a fault with the immobilser system - indicated by the message "start error" - the aam unit is not recognzing the signal from your key.


Try another key - as it could be a fault with the one key - but to be honest with you , its usually vehicle end - and the bad news is, there is no way at all round this, other than contacting your Benz dealer and having them connect up the diagnostic machine / computer to see whats gone wrong.


I feel at this point it will be the receiver unit on the van - but there is nothing at all you can do on a diy basis Im afraid.... you are going to have to call it in.
