Hello,

I managed to brick my ecu in a pretty big way. I used an galleto 1260 cable to download the original bin, and modified it from there. After some modification I written the bin to the ecu, laptop plugged in, car was charging, and I didn't have any error. I was very surprized when the car didn't start.When I tried to read the ecu I don't get any response.

So I went to a ,,pro" tuner to recover my ecu, he took my original bin copied with the galleto cable, the nice bit is that it still doesn't start. Si I bought a galleto cable and made a bench so I can write it in boot mode ( don't know why but the ecu doesn't enter boot mode in the car. )

Now I can enter in boot mode every time and write whatever I want, but the car doesn't start, I don't get any reading from it, or ecu id. I tried original files from the web but with the same result. Any suggestions?

The car is an VW lupo 3l, from 2001. I wanted to make an ecu tune with a bit more hp. I need the car ASAP because it's my daily commute vehicle, the other car is a diesel guzzling monster that leaves my pockets dry pretty fast. :D

Can you just confirm for me the procedure you are using to get boot read/write the ecu? As I'm not sure if we're confusing boot read/write with bench read/write. Which is quite different for the purpose of what we might need.

Then it might be worth uploading a read from the ecu as it is (in the no-start condition) so somebody can check the flash consistency.

I made myself a bench using a PC source for a steady 12.75V, made the wiring harness, and ground te pin 24 on the AM29F400BT. The in MPPS i select generic and the EDC15+. And I write it with the bin.
I know what I'm doing, it's not my first project, just the first time I work with a VW and the edc15. :)

Update: I uploaded the bin from the 1.4 tdi and it boots on it's own, i can get the ECU id, etc. These ECU's are really bullet proof :))

This is the original bin downloaded with the galleto. I suspect something is missing but the filesize is spot on...

That's allright, I just get a lot of people saying they've r/w with a bootloader when they've literally just stuck it on bench!

checks look okay with the uploaded file, i assume it's a none starter if it's written with bootloader with this file?

Yes the original software from the ecu is a non starter, and I have checked the check sum in VAGEDCSuite and everything seemed ok. The 1.4tdi software doesn't know what to do with the tiptronic gearbox :), I found another software for the lupo 3l, but I'm waiting for the battery to charge up completely before attempting another start.

Update: It starts with another 3l software, but the immobilizer kicks in, can I extract the immo part from the original bin to the new one?

some programs such as mpps if you are lucky can unlock the ecu

guys anybody have file for EDC15p+ TDI PD 2003 1,9 96kW boot mode?

or I can use OBD read for boot? thanks

That's true , this ECU can make suprise on the bench and nobody knows why, especialy when so much people waiting for efect of your job :D

For me the best for recover is old old machine - KWP2000+.
