Start here
What's the car actually doing?
Most people arrive with a symptom, not a part number. If any of these sound familiar, the ECU is worth testing before it's replaced.
⚡
Won't start or cuts out
Cranks but won't fire, or dies without warning once warm.
🐌
Stuck in limp mode
Power suddenly limited, revs capped, warning lights on the dash.
🔧
Faults that keep returning
Codes cleared at the garage, back again within a few miles.
📉
Dead speedo or cluster
Gauges frozen, display blank, mileage missing or flickering.

No jargon
How sending a unit in works
Three steps. You don't need to know the part number, and nothing is charged until you've approved the price.
01
Tell us the symptoms
Message us the registration and what the car is doing. We'll confirm whether the ECU is the likely culprit and how to remove it.
02
Post it to the workshop
Send the unit to us in any padded box. We test it on the bench and send you a written report with a fixed price.
03
Fitted and back on the road
Approve the quote and we repair, re-test and return it coded to your vehicle, ready to plug straight back in.

Why us
Repair, not replace
A main dealer will sell you a new unit and the programming to go with it. In most cases the fault is a handful of components on a board we can rebuild.

Before you send it
Questions we get asked
No. Because we repair your original unit rather than replacing it, your existing coding, immobiliser data and keys are retained. It plugs straight back in.
You pay nothing for the testing and we return the unit to you. If a repair isn't economical we'll tell you what a tested exchange unit would cost instead.
Often you don't, and that's fine. Send us the registration and the symptoms and we'll tell you honestly whether it's worth testing before you remove anything.
We'll tell you where it is on your vehicle and what's involved. On most cars it's a handful of bolts and a connector. If you'd rather not, any garage can do it in minutes.
Yes — a large share of our work comes from independent garages. Trade pricing and account terms are available.
Warranty terms to be confirmed — placeholder copy.
