Gearbox Control Panel Repair 5/5

I was quoted £1500 + Vat for for a gearbox company to resolve my issue. By sending the unit to ECUTesting and getting them to repair it I have saved over £1200. I cannot recommend their services highly enough.

Excellent service. 5/5

A great Team that genuinely want to give a professional service. I was updated throughout my ECU process and cannot fault them in anyway. Use with confidence they are fantastic, thank you!
