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!

    My husband usually takes my car here, so it was my first visit. I was pleasantly surprised at how welcoming and... friendly everyone was when I went recently for a MOT. The whole reception area was so clean and comfortable, so I settled down to wait. It was interesting to watch my car being tested through the very large viewing window (see photo)! I like the fact that appointments are available, rather than being told to 'just come in and wait'. The test was completed in record time but I could've stayed a lot longer - it was so relaxing! Oh yes - my car passed! Will use Cardoc for my next service.read more

    I went to CarDoc as had an ongoing issue with one of my tyres, where air frequently needed filling up.They said... they'll inpect it and advise accordingly. I left my car with them as don't live far and after a couple of hours, I received a call adviseing the cause (worn internal seal) and cost to fix, which seemed reasonable.I proceeded with the repair and not had an issue since - it's been a couple of weeks.read more
