Am not an expert in these graphs, looks to me like only a few seconds of graph which is not conclusive although EGR in the first looks like it's working correctly.

 

I will PM you.

Hi Harpster

 

Could you tell me what year/engine you have please? I'm having problems with my '99 110, and it would be really handy to know if some of your numbers would apply to mine?

 

Thanks a lot and good luck!

Alan
