What we do
Car electronics are our main trade. The spanners get plenty of use as well.
ECU cloning
Your old unit's data copied onto a replacement. Fit it and the car starts, with no dealer coding.
ECU repair and diagnostics
Warning lights, limp mode, non-starters. We trace the fault properly before any parts get ordered.
Mileage correction
For replaced or repaired instrument clusters, and readings scrambled by a fault. Set back to the car's true mileage.
Immobiliser cloning Coming soon
Replacement immobilisers matched to your car. Ask when you call and we'll tell you when it's ready.
Air con repairs and regas
Air con blowing warm? We find the fault, fix it and top the gas back up.
Repairs and servicing
Servicing, brakes, suspension and general mechanical work on all makes.
Mileage correction is for genuine cases only. Please bring proof the car is yours.

Common questions
Not sure if it's an ECU job? Ring us. It costs nothing to ask.
How do I know if my ECU is the problem?
Common signs are a warning light that won't clear, an engine that cuts out or won't start, and a code reader that can't connect to the car. Those can have other causes too, so we test first and only blame the ECU when it's proven.
Do I have to buy a new ECU from the dealer?
Usually not. Many units can be repaired, and a used one can be unlocked or cloned to work with your car. That often costs a lot less than a new unit.
Can I fit a second-hand ECU myself?
On most modern cars it won't work straight away, because the unit is coded to the car it came from. It needs unlocking or cloning first, which is what we do.
Is mileage correction legal?
Yes, when it sets the reading to the car's true mileage, for example after an instrument cluster is replaced. Selling a car with a false mileage is illegal, and we won't do that work.
Which cars do you work on?
Most makes and models. Call with your make, model and year and we'll tell you straight away whether we can help.
Do I need to book?
Yes. Ring or message first so we can make sure a ramp and the right kit are free when you arrive.
Got a fault nobody else can fix?
Tell us what the car's doing. We'll tell you if we can sort it, and what it'll cost.
