UK-POLOS.NET - THE VW Polo Forum

Hiya guys and gals. Let me introduce myself; my name is Patrik and i'm located in the southern parts of Sweden. I just got my MKII about a month ago. To be more precise it's a MKII -90, 1,3l engine with cat, oxygen sensor and Digijet injection. So far I have canged the cambelt, made a service on the heater fan. I have also converted it to run on E85.

What I would like to know for starters is if there's any way I can read errorcodes from the digijet system?

I also would like to know what controls the fuelflow when the engine is ideling and, what way do you turn to increse the CO?

Hope you guys can help

The CO control is on the air flow meter, under the blue cap. The idle speed is controlled by a screw on the throttle body. I think http:\\www.rosstech.com can supply the software and the cable for reading the fault codes from this type of ECU.

Thank you for you answer but I still would like to know what controls the fuelflow when the engine is ideling and I would still like to know witch way to turn if I would like to increase/decrease the CO. I have ross-techs software and I have a cable but I can't seem to find the connector on the car.
I allready know that the CO screw is under the blue cap and that the idle screw is on the trottlebody (had the trottlebody of 2 weeks ago and cleaned it)
