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!

Free 1-Year Additional Guarantee (Parts & Labour)

All work we carry out comes with a FREE 1-year or 12,000 miles (whichever comes first) parts and labour guarantee. That’s on top of the standard manufacturer’s guarantee.

    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!

    March 2022: Very good garage, they updated me about my car throughout the day and were transparent about costs and... what’s required. Paul explained what needed changing in depth and why it needed changing. Thank you Cardoc for attaining a new customer.September 2023: Back again for a service on my car and even due to age of the vehicle and wear and tear items, no upselling made which is very difficult to find nowadays. Really appreciate the work they do and service provided is impeccable. Thank you again Cardocread more
