Another example: many garages charge £74.33 per hour on average in the UK, but some garages in London charge up to £215 per hour.

It doesn’t help that vehicles on the whole are becoming more difficult to repair. According to Art Jabocben, VP of CarMD, modern cars are designed to last longer, but this comes at a cost. According to Art, most modern cars have sophisticated on-board diagnostic systems. Unfortunately, these systems take up a lot of space and make it harder for people to do repairs at home. Still, forewarned is forearmed, so in this post, we’re covering the 10 most common repairs and modifications in the UK.

  1. Aftermarket alarm removal.
  2. Average Cost: £51.01

    If you have a MoT coming up, take heed: adding aftermarket equipment to your car draws much-needed power from the electrical system. This can cause critical systems to fail or perform poorly.

  3. Ignition coils.
  4. Average Cost: £143.36

    Ignition coils, AKA spark coils, provide the energy required by the spark plugs to ignite gasoline. Failing ignition coils can cause the following symptoms:

    • Backfiring
    • Slow start
    • Low fuel economy
    • Misfiring engine
    • Stalling
  5. Intake manifold gaskets.
  6. Average Cost: £219.76

  7. Engine coolant temperature sensor.
  8. This sensor is essential to the health of your engine, and it breaks frequently. A faulty engine coolant temperature sensor can prove disastrous if you have a leak in your coolant line.

  9. Oxygen sensor.
  10. Average Cost: £160.54

    The oxygen sensor monitors the amount of oxygen in the car’s exhaust and feeds data into the on-board computer. Many car manufactures have taken to covering this sensor with a grated piece of metal that requires a specific tool to remove. Unfortunately, this makes home replacement almost impossible.

  11. Catalytic converter.
  12. Average cost: £673.73

    The catalytic converter controls the car’s emission system. This component can last for the life of the car, but if you go too long between spark plug changes, it can become damaged.

  13. Fuel Caps
  14. Average cost: 40p plus labour Loose or missing fuel caps are common. If left unattended, a loose fuel capcan cause a 0.5 percent drop in gas mileage.

  15. Spark Plugs
  16. Average cost: £209.41

  17. Mass airflow sensor
  18. Average cost: £253.31

Preventing Costly Car Repairs

Use the following six tips as a starting point.

  • Consult your owner’s manual for your car’s maintenance schedule. Follow this schedule as much as possible. Being proactive is the best way to avoid costly repairs.
  • If you notice rough idling, squeaky brakes or stalling, get your car inspected right away. Any of these issues can cause you to fail the MoT and finding the root cause early will save you money.
  • Frequently check your car’s fluids, filters and spark plugs. Change as needed.
  • Use high-performance synthetic oil. It is more resilient to break-down and it will keep your engine cooler.
  • Common car repairs like keeping your tires properly inflated. If your tires are under-inflated, you’ll use more gas than you need to. If they’re over inflated, they could blow out. You must maintain at least 1.66mm of tire tread to pass your MOT.
  • f you notice strange noises while driving, consult your owner’s manual. There are plenty of innocuous engine noises, but it’s a good idea to make a note of anything you hear just in case.
  • That said, never ignore a persistent symptom. Often, a minor issue may cause an ominous noise or vibration. But if you ignore a failing component, you may cause a much more expensive component to fail.
