Car Diagnostics Harrow

Same Day Service Monday To Saturday

We provide same day car diagnostics in Harrow, Monday to Saturday, for all makes and models at our Bosch approved car garage.

Car or vehicle diagnostics are ways to check for and identify and fix faults. Modern cars usually flag up error codes or specific lights on the instrument panel or dashboard when something is wrong. We can identify the fault and put it right for you.

Vehicles are now full of high-spec tech, microchips and processors. Specialist diagnostic equipment can detect problems and quickly and accurately test your vehicle’s performance, showing any issues or faults. Typical engine diagnostic issues include problems with the oil tank, fuel tank and transmission systems (gears and clutch).

Our car diagnostics service centre in Harrow is in easy reach for those in and around Harrow, Stanmore, Pinner, Northwood, Ruislip, Hatch End, Wealdstone, Headstone Lane, Rayners Lane, Northolt and surrounding North West London areas.

What Will A Car Diagnostic Test Tell You?

A car diagnostic test will provide more detail on the following issues from:

Engine
Transmission
Ignition
Throttle
Exhaust
Brakes
PCV valve
Engine RPM
Air and coolant temperature
Crankshaft and camshaft position
Spark plugs
And more!

Brought my car in after lights appearing on the dash. After it being checked over, Paul informed me of exactly what was wrong and how to fix it. He was really informative and honest. I cannot fault the work done on my vehicle and the customer service received. I will definitely be returning!

Great professional comprehensive service, I would rate this place better than a dealership. Took my mercedes, which had... loads of small to medium issues which had piled up. Cardoc Mahesh was amazing, lhe listened, they investigated, communicated and fixed all the issues. Tyres, a slow puncture no one else could fix, key fob not working, alarm siren not working, and they fixed issues I did not tell them about and all at a very competitive price point. I don't normally write such long reviews but this experience deserves it! Thank you 😊read more
