Hi,

Looks like you did well reading the codes. Now, I do not know what code #7 & #17 translate to. Your engine # is 103.942. The codes I posted are for engine 102.985. Please do a search in this forum for '103 codes' and see what you find. As far as the CE light not coming on, it could be temporary. Sometimes it takes a while before it comes back on.
