Check if we service your module
Paste an ECU type or part number from your faulty module and see instantly whether we cover it, what services we offer, and the starting price.
Database includes ECUs, BCMs, FEM/BDC, CEM, instrument clusters, TCUs, ABS modules and more.
Our coverage database grows with every job we complete. If your specific part number isn’t listed but the ECU type matches, there’s a strong chance we still cover it - ask us.
Pricing
Pricing is case by case and depends on the vehicle, the service required, and whether it’s a file or a physical module.
Send us the details - we’ll confirm a firm price and turnaround before any work begins. Regular trade customers can set up an account with agreed rates.
