About JC cars / ECU Connection

JC Cars / ECU Connection is a car electronics and diagnostic specialist in Norwich. Its listed services are instrument cluster and ECU repairs. Customers mention diagnosing warning light faults, fuse checks and replacements, key and immobiliser work, and bench-based ECU and body control module work, some by post and some with the car brought in. Several reviewers describe quick turnaround, with one reporting a same-day diagnosis and repair the following day.

Reviewers describe the team as friendly and helpful, and say they explain the work clearly. Some customers report prices lower than those quoted elsewhere, while one reviewer says a bench service for a Dacia immobiliser set was not offered and that the car needed to be brought in, with a long wait.

Before you book

Ask for the total price, including the call-out, before the locksmith sets off, and ask whether they will try to open a locked door without drilling it. If the price changes a lot once they arrive, you can say no. Our guide to choosing a locksmith covers the warning signs.
