Hello, I´m from Brazil.

I have a Polo classic (6KN) and buied a VAG-COM to access the ECU.

What parameters i can adjust with Vag-com in my car? The engine (1.8 liter M.P.F.I - Gasoline) and ECU (MAGNETTI MARELLI 1AVB) is similar with Golf MK3 inBrazil.

Welcome to the Forum.

 

A lot depends on what you have actually purchased - If it is a cheap Chinese copy, maybe you won't be able to do much more than read fault codes and maybe clear (delete) them.

All that I can suggest, is that you experiment with it and see exactly what it will do.

 

Regards.

Hello,

I Tested the VAG-COM in my car and got it read the parameters of sensors in real time and fault codes.  the lambda sensor was in trouble.

With the device i finnaly solved my problem.

I Can´t change parameters or reset adaptive parameters in my car, but I believe it is because the ECU is old.

My engine was rectified to primary measure three weeks ago, the car is very good now.

 

follow one picture of my car:.

Glad that you have the problem sorted out.
