Hello everyone.
I ask for help please.
I'm struggling with the car all day.
Audi a3-1.9TDI.
AHF
1998
81kW.
Car has problem with the hot start. I read two eprom M27C1001, I put two new AM29F010B with different files modified with hot start fix, the car starts but it works with two cylinders and vibrates that is scary.If I write the original file in AM29F010B car works OK, but it's hard to start hot.
I ask for help to modify my file and calculate cheksum.
Thank.

Thanks mack0r, now with unplugged temperature sensor starts well, but if I put 45-90 degrees it still does the same.

Thank you . The truth is that this is the first car I see that behaves like this, I do not know what to think, broken can not be because with its original file it works, with the modified file I'm afraid that the engine will break.

I have tried at least 10 different files and it does the same but at different temperatures. In the last week I had an audi like AHF and it had coding 00002 manual. I am already fed up with this car.
