Hi there.

Welcome to

I hope I can help you today, but first I need to ask you a couple of questions.

1. What was the reason for changing the ECU in the first place?

2. Was it only the ECU you transferred from the other vehicle?

3. Was it a garage that swapped it or yourself?

I look forward to your replies
