This identifier not only serves as the vehicle’s fingerprint, providing details such as its manufacturer, attributes, and unique features, but also plays a critical role in tracking recalls, registrations, warranty claims, and theft.

The importance of understanding and using VIN decoders is paramount for a variety of stakeholders including buyers, sellers, manufacturers, and regulatory bodies for cars, motorbikes, trucks and vans.

These are different to registration number plates, which can easily be swapped. These numbers are unique to the vehicle. Locations vary, often they are on the bottom of the windshield or on the drivers door.

The Structure of a Vehicle Identification Number

A Vehicle Identification Number (VIN) consists of 17 characters (digits and capital letters) that act as a unique identifier for the vehicle. The VIN is structured in a specific format that includes the World Manufacturer Identifier (WMI), Vehicle Descriptor Section (VDS), and Vehicle Identifier Section (VIS).

1. World Manufacturer Identifier (WMI): The first three characters of the VIN represent the manufacturer and the country of origin. For example, a VIN starting with “1HG” indicates that the vehicle was manufactured by Honda in the United States.
2. Vehicle Descriptor Section (VDS): Characters four through nine contain information about the vehicle’s model, body type, restraint system, transmission type, and engine code. These details are crucial for accurately identifying the vehicle type and its specifications.
3. Vehicle Identifier Section (VIS): The last eight characters of the VIN provide information that is specific to each individual vehicle. This section usually includes a serial number and can tell you about the vehicle’s production year and the plant where it was manufactured.

How a VIN Decoder Works

A VIN decoder extracts information from the VIN by matching each section of the number with a corresponding set of data. The decoding process involves the following steps:

• Input: The full 17-character VIN is input into the VIN decoder.
• Analysis: The decoder identifies and segments the WMI, VDS, and VIS.
• Cross-Referencing: Each segment of the VIN is cross-referenced with a comprehensive database that contains manufacturer codes and vehicle attributes.
• Output: The decoder outputs a report that details everything from the vehicle’s manufacturing year to its engine size.

Uses of VIN Decoding

The applications of VIN decoding are diverse, extending across various facets of automotive and related industries:

• Vehicle Buyers: Potential car buyers use VIN decoding to verify vehicle details and ensure that the vehicle matches the seller’s description. This is crucial for avoiding fraud and purchasing vehicles that may have been stolen or tampered with.
• Automobile Sellers and Dealerships: Sellers can use VIN decoders to provide accurate information to potential buyers and ensure that they are compliant with legal and regulatory standards.
• Law Enforcement: Law enforcement agencies, police or the DVLA use VIN decoders to track down stolen vehicles and verify vehicle registration details during driver stops or inspections.
• Insurance Companies: Insurers use VINs to accurately assess the risk associated with insuring a particular vehicle, determining premiums based on the model’s theft rates, safety records, and replacement costs.
• Manufacturers and Regulatory Bodies: Manufacturers may use VIN decoding to track vehicles after production for recalls, warranty claims, or customer service purposes. Regulatory bodies may use the VIN to ensure compliance with safety and environmental standards.

Challenges and Considerations in VIN Decoding

While VIN decoding is highly beneficial, it also comes with challenges:

• Data Privacy and Security: Handling sensitive data responsibly is critical, especially when decoding VINs that relate to personal ownership or vehicle history.
• Accuracy of Data: The reliability of a VIN decoder depends on the database it uses. Outdated or incorrect data can lead to errors in the decoding process.
• Standardization Issues: Although most countries adhere to the 17-character VIN system, there are differences in the codes and standards used, which can complicate the decoding process.

Conclusion

VIN decoders are powerful tools that serve multiple stakeholders in the automotive industry. By providing a deep insight into a vehicle’s identity and history, they play a crucial role in enhancing transparency, compliance, and security in vehicle transactions and management. As the automotive industry continues to evolve with advancements in technology and data management, the functionality and importance of VIN decoders are likely to grow, making them even more integral to automotive industry operations.

What is a tyre pressure monitoring system?

The tyre pressure monitoring system is connected to your vehicle’s Electronic Control Unit (ECU) and uses sensors to automatically update you when the tyre pressure isn’t quite right. This alert will appear as a warning light on your dashboard. It measures the tyre pressure or any pressure imbalances. 

What should you do if the warning light shows?

You may wonder if it’s still safe to drive if the light shows. If the light shows mid-journey, you should take extra care and try to visit a car mechanic as soon as possible. You should check your manufacturer’s guidelines. These details can be found in your owner’s manual, inside the fuel filler flap or on the driver’s door sill.

How does the TPMS system work?

There are two types of system: direct and indirect. 

Direct systems use radio sensors inside each wheel to measure the tyre inflation pressures.

Indirect systems are linked to the vehicle’s ABS sensors. They measure and compare the rotational speeds of the tyres, which gives a good indicator of their pressure.

How reliable is it?

You may wonder if you can solely rely on the modern TPMS system. Or should you still do your manual checks?

It’s not recommended that you solely rely on the TPMS. You should still do your manual tyre pressure checks. It’s best practice to check your tyre pressure measurements against the recommended manufacturer settings. You can use a gauge to do this.

How important is the system?

Since 2015, an inoperative or faulty TPMS system will result in an MOT failure. So, if that’s anything to go by, it’s pretty important.

As of November 2014, all new passenger vehicles sold in the EU must be equipped with a tyre pressure monitoring system (TPMS). This means any new cars should have this system fitted. Or, if you’re buying a used car, if it dates from November 2014, then it should have the TPMS. 

You should get the system serviced every once in a while to ensure it remains working properly, and won’t cause you to fail an MOT inspection. 

Tyre pressure will always be checked if you are purchasing a new car, and it is advisable to ensure the tyre pressure is alright when buying a used car. JJ Premium Cars, a dealership selling used cars in Peterborough, do a 114 point check beforehand.

What happens at a service?

Get an MOT or book in for a service

Your car may have been sat for a while or you might have missed its last service because of the pandemic, either way you may need to get it booked in for a quick health check. You may find that a lot of the garages in your local area have a number of different options available, from a full health screening to a quick once over. If a check does show you need repairs, there are ways to spread the cost that can help you manage your budget.

What checks can you do at home?

If you don’t want to take your car in for a service or MOT, there are a number of checks you can do at home to make sure you’re ready to hit the road again!

Tyre pressure – many cars nowadays will have tyre pressure monitors built into their computer system. If yours hasn’t popped up but you want to check it, head to your local petrol station, check the number that indicates how high your tyres need to be, and use the machine to pump them up. It may only be marginal, but it’s important that your tyres are inflated to the correct level.

Check tyre tread – if you’re planning on taking your car in for an MOT, don’t forget that if your tread is under 3mm, it will fail. If you don’t have a tread checker at home, the simplest way to test them is to put a 20 pence piece into the tyre tread. If you see the rim of the coin, your tyres will need changing.

Other checks that are easy to do at home are:

• Engine oil
• Windscreen wipers
• Windscreen for chips
• Lights, indicators, hazards and beam lights

Make sure your finance and insurance are all up-to-date

Although there’s likely not a lot to do where your finance is concerned, make sure you check all your documentation is up to date. The same applies for your insurance, as you may have opted to register your car as SORN during the pandemic. If you’re looking to change companies, make sure you shop around on comparison sites to get the best possible deal!

How do shock absorbers work?

The hydraulic systems use pressurized fluids. To deliver tremendous steam, the hydraulic press squash a little bit of fluid. The basic idea behind a hydraulic unit is accessible: at one point, the energy used is passed to another point by an incompressible fluid. The solvent is almost always a type of gasoline. Shock absorbers work together to provide a smooth ride. They are placed at the front and rear of the vehicle. For example, shock absorbers Bilstein B8 are designed for the front axle manufacturers might choose to go with something else. So, each case is different from the other.

Features of Bilstein shock absorbers.

Since the components and tolerances used in the production process are consistent, Bilstein is superior to other shocks. Due to which these shocks last more than twice compared to any other shock absorbers.

You will boost the dynamics with the aid of Bilstein absorbers. It will help in maintaining proper grip and improving lane-stability in day-to-day scenarios.

Front shock absorber replacement.

Place the vehicle on a level surface, then jack the forward portion, and afterward introduce the blocks to park the vehicle safely.

Break the nodes and bolts by using a hammer. Open the hood, locate the top shock bolt, use the hook and remove the nozzle, the washing machine, and the rubber. Start by lifting the car and sticking the jack in the air on both sides of the car. There is a retaining bolt on the bottom of the front shock absorbers that have to be loosened to remove the shock. The absorber is isolated from the A-frame lower portion. Ease the front shock absorbers as they are withdrawn. The last shock will be carried to the top of the box. Tighten the holding bolts to the same torque as the owner’s manual reads out.

Change the rear shock absorber.

The procedure starts in the same manner as the process above. The car is parked on a flat field, and the wheels are chocked or inserted into machinery. Following this, the wheels are detached. The lower shock bolt is then reached from underneath the car. For frontal shocks, the top boults are normally accessible under the hat. Some vehicles can reach rear shocks from below the vehicle. You swap the new ones for the old ones and keep up the measures.

Prior to your MOT, there are a few ways in which you can prevent your car from failing an MOT test but what do you do if your car does fail? Can you still drive it? Is it safe to be on the roads?

How do you know if your car has failed an MOT?

After your MOT test you will receive a test result. After the MOT rule changes in 2018, your test result will fall into 1 of 3 categories, dangerous, major or minor. An MOT fail consists of either a dangerous or major test result.

• A dangerous fault is a direct and immediate risk to road safety or has a serious impact on the environment and the vehicles should not be driven until the fault is repaired. Dangerous faults can be having no functioning brake lights, or a steering wheel so loose that it’s likely to become detached.
• A major test result is a risk which may be a risk to road safety, and you could be able to still drive your car if it is still deemed roadworthy. However, you should get the fault fixed as soon as possible.

Your car has failed its MOT: what do you do next?

You will be provided with a ‘Refusal of an MOT test certificate’ (VT30) which will have your details and your cars details, the MOT test number and also the specific reasons why your car did not pass its MOT.

Booking a MOT retest

Your car is very important to you, so you want to get it back on the road as soon as possible! You can leave your car with the MOT centre if they also do repairs and book it in for a retest or if you want to take it to a different repair and test centre, you can take the car elsewhere but remember to take the VT30 certificate with you! If your car has a dangerous fault which may be costly to repair, you could consider getting a used car on finance instead!

If you want to take a retest, you will need to fix the issue on your refusal test certificate first. There are a few different retest options available.

• Leave it to be fixed. You can get your vehicle fixed immediately and if the work is repaired within 10 working days then you can get a ‘partial retest’ which only test the repair which needed doing. This can save you time and money!
• Get the vehicle fixed elsewhere. You can take your car to be repaired at a repair centre and then bring the car back to the MOT test centre within 1 working day for a free partial retest.
• Fix it within 10 working days. You can take the car to be fixed elsewhere and then bring the car back within 10 working days. You can then get a partial retest, but you will have to pay for a retest, it is usually half of the original testing cost.
• Bring the car back after 10 working days. If you bring your car back 10 days after the original MOT test with the vehicle fixed, then you will have to pay for a full MOT.

Can I appeal a failed MOT?

If your car has failed its MOT and you feel like it has been an unfair outcome, then you can choose to appeal it. You should discuss your MOT test result with the MOT centre first to fully understand the faults and why they failed your car, this can promote clear communication on both sides. You should then send an email or letter to the DVSA within 14 working days of your MOT test and they will discuss your appeal with you. If the DVSA recommend that you get a retest, you will need to pay the full amount yourself and if your appeal is successful then you will receive some or all of the MOT test fee.
