Water damage, blown drivers, corrupted EEPROM, known faults on specific ECUs we see all the time. We diagnose and repair on the bench, then refit. Most repairs are a fraction of the price of a new dealer unit.
Most ECU faults are repairable — water-damaged tracks, failed transistors, corrupt EEPROM, common known issues on specific models. We diagnose, repair and refit, usually for far less than a dealer replacement.
Many ECU failures are well-known, repeatable, and absolutely repairable. We see the same Bosch, Siemens, Continental and Delphi units week after week — and we know exactly what fails on each.
Corroded tracks, oxidised pins, shorted components from leaks. Cleaned, repaired and re-sealed. Often fully recoverable when caught early — even more so if you don't crank the engine after the leak.
Output transistors that drive injectors, coils or solenoids can fail. We replace the affected drivers at component level — much cheaper than swapping the whole ECU.
The little memory chip that stores adaptation data, immobiliser keys, mileage, VIN. When it gets corrupt, the ECU goes weird. We rewrite or replace the chip.
Specific ECU part numbers have specific common failures — we know them. Bosch EDC17, Siemens PCR2.1, Continental SIM271 and many others. If yours has a known issue, we fix it the right way.
Don't want a mobile visit? Send the ECU to us, we repair on the bench and post it back. Useful for older cars, project builds, or jobs where the car's off the road.
If we can't repair your ECU, you don't pay for the diagnosis. We'll honestly tell you when cloning or adaptation is the better route, and quote that separately.
Four steps from first message to keys-back. Most jobs the same week.
Call, text, WhatsApp or use the form. Tell us the make, model, year and what you'd like done.
Usually within minutes, 7 days a week. Fixed price, no obligation, no pressure to book.
Driveway, workplace, car park — wherever suits. Most jobs are wrapped in a single visit.
You see the result, you check it's working, then you pay. Card, transfer or cash.
Most quotes back within minutes, 7 days a week. Call, or message on WhatsApp.
Water got into the engine bay, ECU was soaked. Dashtech cleaned and rebuilt the tracks, car's been running fine for months since.
Car wouldn't start, told by two garages I needed a new ECU. Dashtech repaired the original at component level. Massive saving.
Known fault on my model — Dashtech recognised it from the symptoms before I even handed over the ECU. Repaired in a week, posted back, all good.
EEPROM was corrupt — random codes, weird behaviour. Dashtech read the chip directly and rebuilt the data. Saved a fortune on a new unit.
Honest about whether my ECU was repairable. Recommended cloning instead because it was cheaper for my case. Did that job too, no upsell.
Blown injector driver, dealer wanted to swap the whole ECU. Dashtech replaced the failed component for a fraction of the price. Months on, still perfect.
