Re: Can't read fault codes on 2003 Vivaro diesel

Hi Steve,

That is an really interesting mapping on those codes. Would you know
where there might be a list available of these mappings? Or a list of
the codes for the Renault engines?

Am I right in thinking that you're reading them directly from the
tool itself there?

Many thanks,

d
