Common cluster faults

Four ECU services,
one mobile specialist.

Whether your ECU has failed outright, you've bought a replacement that won't talk to the car, or you need a complete clone — we cover the lot.

01 / Cloning

ECU cloning.

Failed ECU? We read the data from the original (where possible) and write it to a donor unit — fully cloned, fully matched. The car accepts the new ECU as if it were the original, no dealer trip needed.

Driveway clone
02 / Coding

ECU coding.

New ECU fitted? It needs coding so the car recognises it — VIN, immobiliser, injector codes, optional features. We code at manufacturer level so the unit talks to the rest of the car correctly from the off.

Coded to your VIN
03 / Used ECU

Used ECU adaptations.

Sourced a used ECU from a breaker? We adapt it to your car — virginise where needed, change the immobiliser data, marry it to your keys, and code it to your VIN. The cheapest route to a working ECU on most cars.

Adapted & married
04 / Repair

ECU repairs.

Water damage, internal short, capacitor failure, processor fault. Many ECUs that "need replacing" can actually be repaired at component level for a fraction of the cost. We diagnose first and tell you honestly what's economical.

Repaired in-house
05 / Immobiliser

Immobiliser issues.

Car cranking but not starting, key not recognised, or post-swap immobiliser lockout? Most immobiliser problems come down to ECU/cluster/gateway sync. We diagnose the chain and fix the right module.

Sync & reset
06 / Diagnostics

Persistent ECU faults.

Codes that won't clear, ECU comms errors, intermittent stalling or limp-mode events? Read out properly with the right tools, most can be traced to the ECU itself, its inputs, or the wiring. We find the root cause.

How we work

Read first.
Programme properly.

ECU work is precise — wrong data, wrong ID values or skipped sync steps and the car ends up worse than it started. Every job is read, programmed, then verified before we leave.

  1. 01

    Read the ECU & the car

    Manufacturer-level tools to read the ECU's data, fault codes, immobiliser sync state, and adaptation values — so we know exactly what's wrong and what the right approach is.

  2. 02

    Choose: clone, code, adapt, or repair

    Each problem has a right answer. Clone if the data can be read off the original. Code if it's a fresh unit. Adapt if it's a used part. Repair if the silicon's actually fixable. We pick the right route, not the easiest one.

  3. 03

    Verify before we leave

    Engine starting, all systems talking, fault codes cleared, road-test or test-drive as needed. ECU work isn't done until the car proves it works.

Cloned my replacement ECU and got the car running again. Honest, friendly, knows his stuff. Booked again already.

Bought a used ECU from a breaker, dealer wanted significantly more to programme it. Dashtech adapted and coded it on the driveway for half that.

Two garages said my ECU was dead and needed replacing. Dashtech repaired the existing one for a fraction of what a new one would have cost.

Common questions

ECU programming, explained.

What's the difference between cloning, coding, and adapting?
Cloning reads the data from your original ECU (where readable) and writes it to a donor unit — the new one becomes a copy of the old. Coding programmes a fresh, blank ECU to your VIN, immobiliser and options. Adapting takes a used ECU from another car and reconfigures it to work with yours. We pick the right approach based on what you've got.
My ECU is dead — can it be repaired or do I need a new one?
Often, yes. ECUs that "need replacing" frequently have repairable faults — water damage, capacitor failure, internal short circuits, processor issues. We diagnose first and tell you honestly whether repair makes sense. Many cases we save people 70–80% versus a dealer replacement.
Can you programme a used ECU from a breaker yard?
Yes — used ECU adaptation is one of our core services. We virginise where needed, programme the immobiliser data, code to your VIN, and marry it to your keys. The cheapest route to a working ECU on most cars, often a fraction of the cost of new.
How long does ECU programming take?
Most jobs are completed in 60–180 minutes on the driveway. Cloning is usually quickest; full adaptation of a used unit can take longer if multiple modules need syncing. We'll always tell you up front before booking.
Do you cover my make?
BMW, Audi, VW Group, Mercedes, Porsche, Mini, Land Rover, Jaguar, Ford, Vauxhall and most Japanese, Korean and French marques are routine for us. Send the registration over and we'll confirm before booking.
Will the work void my warranty?
If your car's still in manufacturer warranty, dealer ECU work is the safer route. For everything outside warranty — which is most of our customers — independent ECU programming is fully legitimate and increasingly common as cars age out of dealer plans.
