Anyone knows where exactly the DTC's codes are stored in the eeprom or flash?

 It's a R32 ECU (MK5) ME7.1.1. 022 906 032 KG

 I want to remove the lambdas behind the cat, secundaire air pump.

 And when its possible also the fault codes, ABS controller, Gearbox, Gateway, Steering angle sensor etc...

 I have build this engine in a MK2 with manual gearbox and no abs or something on the car.

The check engine light is out, only EPC is on.

 When i try to recode (engine) from DSG to manual gearbox, he don't change this code, maybe first pin needed?

Second question,

I try to read the flash with mpps, but no succes, he give me a error and a emailadres..

When i wil try it in bootmode, what is the best why ?

I damage 1 ecu when i try to bootmode it with a ME7.5 ecu, ground pin 24 and ecu dies.

Of course you need the flash. That's how you disable functions/dtc's.

You need to find CW_CAN_R, as well as the rest of the items detailed in the S4 tuning wiki.

If your tuner can't find the DTC's without help from us, find a new tuner.
