Hello Folks,

I was working on a Vauxhall 1.7cdti Engine code A17DTJ.Its a Denso ECU. I got hit with bad luck big time today.Wanted to do the DPF off for someone. I Jtag,ed it with KTag(Reworked PCB). I managed to read and write without no problem. But after the DPF off Mod file being loaded. Car would not start. Not even cranking the engine. No comunication with the scan tool. (Ivalid data from the CIM.No comunication with the engine ECU etc) U codes logged on Immo.ABS and few different modules. then I reflashed it with the original file. still no luck. As far as i know Ecu Is alive Can hear the buzzing noise from the engine bay.

Checked fuses all ok.
What is wrong here? Is the ECU bricked?
How can I get around this?Is there any solution to this? owner is a taxi driver. I need get this fixed asap. Please help me out on this guys.
You kind consideration would be highly appreciated!
Regards
