01 / Diagnostics and electrical
Faults found, not guessed
Warning lights, intermittent faults, electrical gremlins and control units that have given up. Other garages send us these jobs. You can too.
How a diagnosis works
Four steps, no guesswork
- 01
Tell us what it’s doing
When it happens, how often, any warning lights, and what has already been tried or replaced. It all saves diagnostic time.
- 02
We test, not guess
Genuine dealer and leading aftermarket tools, live data, break-out boxes on the wiring, and the rolling road to recreate faults that only show under load.
- 03
You hear the cause and the price
We explain what we found and what the repair will cost before doing it, so you decide.
- 04
Fixed and checked
Repaired, codes cleared, and the vehicle tested again to prove the fault has gone.
Draft Process to be confirmed with PK reception.

“Easily remedied a problem that two other garages had diagnosed "unfixable". The price was absolutely right, and the diagnostics fee was so worth it!”
Rhiannon Ford Focus

“No dashboard warning lights and no errors on the diagnostic. The guys persevered, I got loaned a car and after some head scratching investigation they sorted it right out.”
Regular customer

Questions people ask
The code reader says it’s a particular part. Why not just replace it?
A fault code tells you which system noticed a problem, not what caused it. We’ve had ABS codes caused by a blocked pipe and “failed ECU” codes caused by a wiring fault. Testing first stops you paying for parts you didn’t need.
My main dealer says the ECU needs replacing. Can you check?
Yes. We test and repair engine and other control units in-house, which is often far cheaper than a new unit from the manufacturer.
Which makes do you work on?
All makes, including Audi, Volkswagen, SEAT, Skoda, Ford, Vauxhall, Peugeot, Citroen, Renault, BMW, Mercedes, Land Rover, Jaguar, Honda, Mazda and Mitsubishi.
The fault comes and goes. Is it worth bringing it in?
Yes, and intermittent faults are a large part of what we do. Note when it happens (speed, temperature, weather). We can often reproduce it on the rolling road while watching live data.
Got a fault nobody can find?
Book online and reception will confirm a time, or ring and talk it through. Have your registration handy.
