Hi mates, i have a trouble, i have a seat leon 1.9 tdi asv ecu hw and sw: 683/530 , one chiptuner gave me a modified ecu file (all checksumms and maps are right, dont talk about this please, its not the first time i put a remapped file on my car).

I didn't have kwp2000 in hand, and i tried to do with commander 1.4.


Reading was ok, but in writing...
when i tried to start the car it cant, later i check with vagcom, and in engine module, numbers from coding are XXXXXXXXXXXXXXXX XXXXXXXXXXXXXX

When i check fault codes says (not exactly)
eeprom incorrectly coded and other fault from confort module.

Later i tried with kwp2000 to put original ecu file, and at first i cannot be able to write original, but i disconnected positive cable from battery and i could write on it.

But the problem isnt solved, in vagcom says the same, and when i try to read with commander 1.4 says non sense kilometers and non sense pin code.

So i think that 29f400 is OK but 24c02 isnt.

Can anyone help me? im upset!

Thanks for all , really

Regards

PD: checksumm is correct, its not the file, im 100% sure, i think its the way commander 1.4 write in the car or something similar (i think i didnt disconnect fuse number 11 :S)
