Opel vivaro 2.0 2012 - Df067 injection multiplexed emission missing

Hi guys, I hope someone can help me with this issue. My Vivaro 2012 2.0 doesn't start. No ecu connection after my friend tried to open my ecu to remap by boot and broke a ceramic capacitor and joined two legs of the chip 40076 bosch, and tried to start the van without checking if he damaged something or not. After that, the van never fired again. I replaced the ecu kit less speedometer, but still the same, I sent it to the garage for one month and 2 weeks, they didn't find the problem, and I paid 300 pounds without them repairing it. I have error code DF067 injection multiplexed emission missing, and oil pressure fault on speedometer. I can access bcm less ecu when I turn the key to position II one of the bosch pump still always on. I need help please

Yes, a friend broke the ecu, tell him to fix your car. The computer is added to the car (to the BCM). You need to add a new / used one to start the car.
