I bought a q50S 2017 salvaged, had to change the ecm, Car won’t start and I get P062b code after replacing the damaged ecm.

If I put gas in the intake, car will start, so It’s look like it’s injector related.

We had to use Consult-3 to change the ecm, VIN is changed successfully in the new ecm, but I can’t complete the reflashing ( flashing old ecm data in the new one)

Keys are reproammed also, so it’s not an immo problem.

HI there

If it will run off fuel in the intake, then it indicates an injector issue or a problem with the computer. Could be fuel pump as well. If you can't reflash the computer then it's got a problem.
