Hi Dominique we are sorry you feel this way from our point of view on your booking it does state that the initial quote you received is for general oil only which is a low grade oil, we didnt want to put this oil in your vehicle as your vehicle requires VW504 oil which is a long life oil and unfortunately costs more and also unlike most independent garages we do not use the oil sump plug we replace them which again is an extra costs but will save you on oil leaks from your oil sump we also use only warranty approved parts and fluids so if your vehicle was in warranty your warranty will not be void this is why we recommended to go with the additional costs. In terms of our location due to the recent weather we understand it was muddy but this is beyond our control.

What does a car diagnostic check do?

A diagnostic check is carried out on your vehicle by a mechanic, who will plug your vehicle into a specialised code reader. It can detect problems with your vehicle which may be difficult to spot manually.

The main components which are tested in a diagnostic check are the car’s:

  • electronic control units (ECUs) - these control various element of the car and its performance including engine running
  • emissions and exhaust sensors
  • braking system
  • electrical components such as central door locking
  • transmission if electronically controlled
  • ignition coils
  • throttle setting
  • fuel injectors
  • air flow and coolant

 

Why is a car diagnostic check important?

A diagnostic check is very important as it can detect a potential problem with your car, even before a breakdown. The computerised equipment scans your vehicle’s system to check for any faults, no matter how minor or major. A diagnostic test is a quick, easy and accurate way to discover any faults and will give you the chance to get them fixed before they turn into bigger and more expensive issues. When your car has a fault, this may show as a warning light on the dashboard. If the light goes out the system will store the fault code so the garage will find this when they do the diagnostic check.

What are the possible signs that your car needs a diagnostic check?

There are many different signs which will indicate that your vehicle needs a diagnostic check. Essentially, if you suspect that there is an issue with your car but don’t know what, you will probably want to book a diagnostic check to find out what the problem is. Here are some of the key signs:

  • Engine warning light - if the engine warning light appears on your dashboard, it’s important to take your vehicle to a garage as soon as possible as there is a wide variety of problems which the light may be flagging up.
  • Strange noises – any strange noises coming from your car need to be checked out before they turn into more serious problem. Some of these sounds may include; whining from the bonnet, abnormally loud exhaust, uneven engine noise, brake squealing or gear crunching.
  • Smoke - if you see smoke or steam coming from under the bonnet, your vehicle may be overheating.
  • Vibrating - if you notice any vibrating or pulling under your brake, the issue may be due to work brake discs or pads. However, it could also indicate a problem with your suspension or steering.

 

How long do car diagnostics take?

You can expect a diagnostic check on your car to take approximately 90 minutes. You may want to allow for more time though as the mechanic who will be carrying out the check might not be available to start right away.

How much does a car diagnostic check cost?

The price of a car diagnostic test can vary, depending on the garage that you visit. Each garage has a fixed price for diagnostic checks, ranging from £30 - £100.

Enter your vehicle registration number and post code into BookMyGarage (at the top of this page) and you can instantly compare diagnostic check pricing from all of the garages in Milton Keynes. As well as price, you can see the garages’ reviews, distance from your post code, extra services offered and availability. You don’t even have to register to get access to all of this information.

Driving in Milton Keynes

Designed originally to accommodate London overspill and housing congestion, Milton Keynes or ‘MK’ as it is locally known, has shed its concrete new town image and flowered into a creative and cultural hub with a thriving music, arts and literature scene.

Milton Keynes’ excellent shopping facilities keep footfall high at thecentre:mk which boasts over 300 shops and is one of the longest indoor shopping centre malls in Europe. The town has also become an extreme sports hotspot. You can water-ski, wakeboard and enjoy other water sports on Willen Lake, or head to Xscape for the UK's longest indoor real-snow ski and boarding slope, along with some superb indoor climbing facilities.
