Hello guys, I'm going to expose you my problem.
I have a Seat ibiza Cupra 1.8T from 2002 (AYP) engine. I have two ecus. The one that came with the car, and another one I have bought to experiment on. Since I got the spare one, it has been on the car.
Today I flashed a new mod (self tune) to the car. Everything went good, and then I tried to start the car. It wanted to start and it did but then, it died and wouldn't start anymore. After another try, I noticed that the EPC and engine lights weren't turning on.
I thought the ECU was bricked. So I took it home, and flashed it again in boot mode. Everything seemed all right.
I came back to the car, and started it. It ran for a few seconds and then died (cold engine runing E85). Again no EPC or engine lights after it died.
I thought that my replacement ecu was somehow faulty. So I put the original ECU in. It started the car as well and died. But it started again (at second igntion cycle) and warmed up. I then turned off the engine to try again, and same symptoms, no lights and no starting.
I put back the spare ECU and first igntion I have all the lights. Second igntion cycle, nothing anymore.
After a few tries, I noticed that if I disconnect the ECU for a few minutes, it always gives me the normal lights, but at the second igntion cycle, same problem, nothing with both ECUs...
Of course no communication with the ECU while no EPC nor engine lights on... When I have the lights, I can connect VCDS and I get a terminal 30 fault code (18010 code)
I checked the fuel pump relay, and it's good. When I have the lights on, at igniton I can hear the pump prime and the car starts right away. At second ignition, I can see the EPC light flash VERY quickly and then it's gone...
My knowledge is very limited, and I can't figure out what's happening.
Some of you might have already seen this problem or might know the solution or things for me to check and cross.
Thank you, for reading.
