Hello people! My name is Gabriel.
I am new to flashing ECUs.
My goal is to flash a car, which is a VW Lupo, 2001, 1.0L, AUC engine, Bosch Motronic ECU, ME7.5.10.
The car has got a problem, related to acceleration, mainly but not only that. The car starts but does not accelerate, and if i insist to press the acceleration pedal in about 10 sec. it shows up o the dashboard, the Check and EPC lights. When that happens, it allows you to accelerate up to 2200-2500rpm maximum. It gives a permanent error on Throttle Actuator, and Lambda Senzor, but other intermitent ones get added while engine runs(about 10-12).
I tested everything on the electrical diagram, wires, voltages, earth connections, replaced Throttle Module and Acceleration Pedal, but no change.
My impression is that there is a corrupt memory inside the ECU. Is it possible to have the right memory flas file, for the car?
I have got a KKL interface, and already installed NefMoto flasfing software. The memory layout is: ME7 229F400BB.

 Thank you!Best regards!

Throttle Actuator, under voltage during basic settings. This and Lambda sensor 1 open circuit are Permanent.
Another one, Throttle control unit, malfunction, intermittent.
I also tried to do -Throttle basic settings- and it gave me error.
These appear first and after a while since the engine started many others appear...up to 12 errors!

Thank you!
