I’ve had two service events with ECU Testing, and would quite possibly use them again. One fault was a detached capacitor inside a Bosch ME7.3.1 ECU - a common issue that benefits from skilled technicians and a clean room to repair durably. It was fixed perfectly and returned very quickly. The other was a body computer with a recognised problem; a unit listed in their books as being open to remedy. Despite this, it was rapidly passed through their hierarchy as unable to be fixed. The positive is that they didn’t hang on for a long time and sent it back smartly, the negative was fairly shallow dialogue - I was left to organise my own Plan B - unexpected when contrasted against prior confidence. I found the client dashboard somewhat useful both times, but still had to resort to phone and email to complete the business cycle. Support staff are consistently pleasant and efficient, this must reflect well on their employer as it’s not a forced manner. Yes, in future I absolutely would consider using ECU Testing again, with the caveat of having worked out a backup plan in advance.
