Audi A4 2002/07 doesn't start after All keys lost with Autel IM508

Dear friends,

I will explain my situation as short as possible: I had an All Keys Lost for an Audi A4 B6 2002/07 2.4L Benzine Cabriolet Automatic. I read immo data from ECU and did key learning, everything seemed to work and the car started. After some hours the customer called me and told me that the car doesn't start, I went back and noticed that the IMMO told my Autel that key is learned and everything is learned and permitted. I tried IMMO OFF which also didn't work.. I have now to mention, this happened before also with an Audi A4 of that kind of year, but I gave fault to the customer... there is something going badly wrong with this Audi's.. does anyone relate or know how to fix it? I have to say, when I twist ignition, I don't hear the fuel pump! Only the first time I cycle the igntion. I also did diagnosis didn't say anything, so I don't understand now why it doesn't tart. This is the second time same problem and now I want to fix it.

ECU is 8E0909552N

I bought a new ECU also and did IMMO OFF but didn't start also.

I used weboctopus to do IMMO OFF on the donor ecu, I will put original file and IMMO OFF file via weboctopus in this thread so you guys can check if immo off was done correctly.

Best regards
