It’s that time of year again – your dreaded MOT date. 

You’re probably already aware of the typical items that could lead to a failure. Worn tyres, damaged brakes and broken seatbelts are all safety-critical features that need to be working properly to get a pass. 

But there are some less typical items you might not be aware of. One everyday item in particular has been catching drivers out for years – air fresheners. 

That’s right, large air fresheners that are deemed to obstruct the driver’s view could cause a major headache for you on your next test. 

In fact, any item on your dashboard could lead to a failure. Poorly positioned sat navs, stickers or other decorations blocking your view could all lead to an accident and therefore a failed MOT.

Our advice is to remove any items from your dashboard that could reduce your visibility as soon as possible and keep up with regular servicing and maintenance to give yourself the best chance of passing your next MOT test. 

Other items you didn’t know could fail your MOT 

To get you ready for your next test, here are some other unexpected items that you didn’t know could lead to an MOT failure. 

Now that you know the items catching drivers out on their tests, you’re ready for your next MOT. Remember, keep your vehicle clean and up to date with regular maintenance, and you’ll significantly improve your chances of a pass. Good luck! 

The everyday item you didn’t know could fail your MOT

If your Ford Focus dashboard has started flickering, going blank, or seems to be showing incorrect readings, you may be dealing with an instrument cluster fault. 

While this can feel alarming, it’s a relatively common issue on specific Ford Focus models and is often repairable without replacing the entire unit. 

A typical Ford Focus instrument cluster repair costs between £150 and £400, and we’ll explain the repair times, cost differences, and warning signs to keep in mind for 2026 below. 

What is the average Ford Focus instrument cluster repair cost?

The average Ford Focus instrument cluster repair cost in the UK typically ranges from £150 to £400, and this cost varies depending on the fault and repair method. 

Minor electrical issues, such as dry solder joints or failed components, are usually at the lower end. At the same time, more complex problems involving circuit boards or communication with the ECU can push costs higher.

For full replacement clusters, particularly new ones that must be coded to your vehicle, prices can rise to £600 to £1,000 or more. 

Here’s a quick overview of what you can expect in 2026:

No matter the repair you’re facing, you can use 

 to split your instrument cluster repair into interest-free repayments.

How long does it take to fix an instrument cluster?

Most Ford Focus instrument cluster repairs take 1 to 3 hours once the unit has been removed. Most repairs can be completed the same day.

If the cluster needs to be sent away for testing or refurbishment, turnaround time is usually 2 to 5 working days. Replacement clusters may take longer due to programming and vehicle coding requirements.

What is the instrument cluster problem on the Ford Focus?

Instrument cluster problems on the Ford Focus are usually caused by electrical faults rather than mechanical failure.

In some cases, communication problems between the cluster and the car’s control modules can cause gauges to stop working or warning lights to appear incorrectly.

These faults are most often seen in older models but can occasionally affect newer vehicles as well.

What years to stay away from the Ford Focus?

Some Ford Focus model years have a higher history of instrument cluster and electrical issues. Drivers and technicians most commonly report problems on 2004–2011 models, particularly the Mk2 generation.

That said, many of these cars are now well understood by specialists, and repairs are usually straightforward. Later models improved overall reliability, though electronic issues can still occur with age and mileage.

A full service history and prompt attention to warning signs matter more than the model year alone.

Common signs of a faulty Ford Focus instrument cluster

Instrument cluster faults often start intermittently before becoming permanent. 

If any of these symptoms appear, it’s best to have the issue checked early to prevent MOT or safety concerns.

Repair vs replacement: which is better for an instrument cluster fault?

In most cases, repair is the better option for a Ford Focus instrument cluster issue.

Specialist repairs address the specific failed components and restore the original cluster, keeping mileage and coding intact.

Replacement is usually only necessary if the cluster is physically damaged or beyond repair. New units require programming and can be costly, while used clusters may cause mileage discrepancies or compatibility issues.

Overall, repair is typically faster, cheaper, and more reliable. But if your mechanic advises a replacement, this is the way to go!

How do I reset my Ford Focus instrument cluster?

A basic instrument cluster reset can sometimes resolve minor software glitches. 

This usually involves disconnecting the battery for 10 to 15 minutes or performing a reset procedure using the ignition and trip button.

However, note that resets will not fix underlying hardware faults. If the issue returns or persists, a professional diagnosis is required to avoid masking a more serious problem.

Can you drive with a faulty instrument cluster?

Technically, yes, you can drive with a faulty instrument cluster — but it’s not recommended.

Driving without accurate speed, warning lights, or fuel readings increases the risk of speeding, breakdowns, collisions, or engine damage. You may also miss critical alerts such as overheating or brake system warnings.

For safety reasons, instrument cluster faults should be addressed promptly.

Can instrument cluster faults cause an MOT failure?

Yes. A faulty instrument cluster can lead to an MOT failure, particularly if warning lights such as ABS, airbag, or engine management lights are illuminated or if the speedometer is not functioning correctly.

Even if the car drives normally, dashboard warning systems must operate correctly to pass an MOT. Get these repaired as soon as possible.

Alongside instrument cluster issues, common Ford Focus repairs include:

Keeping up with routine servicing helps reduce the likelihood of electrical and mechanical problems. So, if you notice anything outside of the ordinary, this is your sign to get it checked out. 

Ford Focus instrument cluster repair cost faults are common but usually affordable to fix, especially when dealt with promptly!

Ford Focus Instrument Cluster Repair Cost

Airbags have been standard fitment on all cars for the last few decades, and for good reason; they help reduce injury in the event of a collision. But, like any additional component in a car, they cost money to replace should something go wrong. 

This article takes a look at the costs associated with an airbag replacement or repair.

If your airbags have deployed because of an accident or fault, expect to pay anywhere from £200 to £2,000+ to repair the damage.

However, in most cases its best to let your insurance assess with and deal with the car. Often, if the airbags have deployed, it means the car will be uneconomical to repair, and as such will be considered a write-off.

If you're facing a repair bill for your airbag replacement, Bumper's 

 can help split the cost without any interest.

If the damage to the rest of the car is repairable and has been deemed safe, it is possible to replace the airbags. In most cases, they will also cause damage to various parts of the interior, such as the steering wheel, dashboard and seats. 

Along with the airbags needing replacing, it is quite likely that the seatbelt pre-tensioners will have activated too. These are explosive charges that pull occupants into the seat, and only work once. 

The time it will take the garage to replace the airbags and repair any damaged interior panels will depend on the number of airbags deployed and the availability of parts.

In most cases, your insurer will first conduct an assessment of the damage to see if it’s worth repairing, which can add another few days to a week.

After the damage has been assessed, new parts will be ordered, usually directly from the manufacturer, and fitted. In total, this can take anywhere from a few days to a few months.

No, airbags serve a very important role, and do not work twice. Once they have deployed, they need to be replaced. They are also likely to deposit debris and gases into the car, something that will not be safe to be around. 

Furthermore, any collision forceful enough to set off airbags also means the car should be fully inspected by a professional before being driven.

This is to ensure the various other safety components, such as impact/crash bars and crumple zones, are not damaged. 

In October, the largest ever vehicle recall was issued, after a fault was discovered with certain airbags made by now-folded Japanese company Takata.

The recall affects cars from many manufacturers, including Citroen, BMW, Toyota and more. It covers a wide range of products, made between 2002 and 2018, in total, around 67 million airbag units are affected.

Whilst originally formed to make their own sports cars, Abarth is best known for their association with Fiat, making performance versions of many of their models over the years, including the Abarth 595, the Punto Evo and the 124. 

If your Abarth needs work done, from routine servicing to mechanical repairs, read on to get an idea of the likely costs you should expect to pay.

These are some rough estimates for servicing costs on Abarth models

Servicing prolongs the life of your car and is likely to be a requirement if the car is leased or financed. 

Not only do large servicing bills increase the annual costs of running a car, but they may also mean that previous owners are less likely to have serviced the car at the dealership, if buying secondhand.

It’s essential to change your car's cambelt within the recommended intervals, so as to avoid much larger repair bills should it break whilst driving.

Suspension components for a regular Fiat 500 are usually pretty well priced, as the cars are simple and plentiful. The Abarth parts, however, are a little more specialised, with fewer cars on the road, meaning they are more expensive.

Bodywork repair costs are usually only determined by the extent and location of the damage, and not necessarily the model or make of the car. However, there are some paint codes that are particularly difficult to match, increasing the costs.

Engines are typically quite expensive to repair as they are very complex and require specialist tools. The Abarth 500 and 595 have the added disadvantage that they are quite tightly packaged, meaning some jobs take more time than on other cars.

If you have any of the costs listed above looming, such as bodywork damage or a knock from your suspension, Bumper can help spread the cost. Split your bill into monthly payments with Bumper's

Water can be extremely damaging to your car if it gets in the wrong places. If water is leaking into your car from a sunroof or door seal, it's important to get it fixed as soon as possible to avoid further damage. 

How much does it cost to repair a car water leak?

Repairing a water leak on your car can cost between £40 and £350+, depending on the cause of the leak and the type of car it is. 

In some cases, a leak is caused by a misfitted seal or one that has come loose. It’s worth checking this yourself before taking the car to a garage, but if you did, it shouldn’t cost more than £40-50 for the mechanic to refit the seal.

It’s also quite common for seals to perish and split over time. If this is the case, the seal will need to be replaced entirely. These can range in price, typically costing between £50-100 for a door or boot seal. Don’t forget to factor in labour costs if you're getting a garage to fit it. 

Sunroofs are a common source of water leaks, either due to perished or damaged seals, or a mechanism that is no longer closing the roof properly. Repairing a leaking sunroof can cost anywhere from £40 for a new seal to £200+ if the mechanism needs to be replaced or repaired.

What are some common causes of car water leaks?

Any place that opens, such as a door or window, can be a source for water leaks, but these are some common places to check first:

It’s not always immediately obvious that you have a water leak, but noticing one or more of the following common symptoms should necessitate having a look for the source of the leak. 

Issues resulting from a water leak can range from some damp carpets to incredibly expensive electrical repairs, depending on the car and the source of the leak. 

At the least, an ongoing water leak is likely to cause a musty smell, and issues with the windscreen fogging up in cold weather. 

If left for a long period of time, mould can easily begin to form in waterlogged carpets and upholstery. This is usually fairly easy to clean off, but in some cases can mark fabrics. Not to mention the health issues!

In certain cars, the consequences can be much more severe, especially if the car’s ECU or wiring is located anywhere the water is leaking or running, repairs can run to thousands of pounds. Even a corroded earth connection can cause a multitude of problems.

Car sills are often-overlooked parts of your vehicle, yet damage can be both unsightly and costly. Car sill damage repair costs can range from £80 to over £600.

From minor scratches along the bottom of your car to rusted or dented panels, knowing the typical repair costs and options helps you make informed decisions. 

This guide covers everything you need to know about car sill repairs in the UK.

Car sill repair costs for minor scratches or dents typically range from £80 to £200, while more extensive rust removal or panel replacement can cost £250 to £600+.

If the car's damage is more severe, you’ll likely have to pay more. The same goes for a full replacement rather than a partial one. 

Luxury or high-end cars may also have higher car sill costs. However, you can use 

 to split any car sill repair costs into interest-free repayments.

Here’s an estimate of car sill repair costs in 2026.

Yes. Sills can be replaced rather than touched up if the metal is severely corroded or structurally compromised. 

Replacement involves removing the old sill, preparing the area, fitting the new panel, and repainting it to match the rest of the car.

Car sills are the sections of the body located at the bottom of the door openings, running along the length of the car. 

While very important, many drivers don’t know the proper name for this part!

Sills provide structural support and help protect the chassis from damage. They also contribute to the vehicle’s overall stability.

A sill typically needs replacing if rust has eaten through the metal or if it’s bent from an impact. Replacements are also needed if structural integrity is compromised. 

On the other hand, small dents or superficial scratches usually only require repair and repainting.

Repair times depend on the type of sill work needed.

More extensive jobs may require additional time for paint drying and curing. In these cases, your mechanic will give you an estimated finish time.

Yes, car sills play a very important structural role. They contribute to chassis strength and help protect occupants in side-impact crashes. 

While cosmetic damage may not affect safety, significant rust or bent panels can compromise structural integrity, making timely repair or replacement essential. 

If left unchecked, you may end up with costly repairs in the future.

Is it worth claiming car insurance for a sill scratch?

Whether to claim depends on the repair cost and your policy excess. 

Minor scratches may cost less than your excess, so it might be more cost-effective to pay out of pocket. 

Remember that comprehensive insurance may cover damage caused by accidents or vandalism, so sill damage from wear and tear won’t be covered. Always check your policy details.

Preventing sill damage involves regular inspection and maintenance. 

Here are some prevention habits you can adopt to keep your sills protected against wear and tear:

Car sill damage can be more than just a cosmetic issue, so don’t delay looking into this integral car part. 

Early attention to scratches or rust prevents costly replacements and preserves the structural integrity of your vehicle. Hopefully, the car sill damage repair cost information on this page has given you a starting point for your repair!

How much does it cost to repair a car sill?

A seized brake caliper can occur on almost any car, and with brakes being such a vital safety system, it’s important to get any potential issues fixed as soon as possible. In this article, we’ll discuss how much it’s likely to cost to repair a seized brake caliper.

It will cost between £125 and £600 to repair a seized brake caliper, but the make and model of the car, as well as the extent of the damage, can affect the final cost.

In some cases, the caliper can be disassembled, the slider pins cleaned and re-greased, and put back on the car. This should only take an hour or so in labour, typically costing around £85 and £175.

In more severe cases, where the caliper needs to be fully rebuilt, a new one will be fitted, generally costing anywhere from £150 and £300 per corner. 

If the brake caliper has been seized for some time, and caused the brakes to overheat, this will require a new disc and set of brake pads too, likely bringing the bill to around £600.

If you have a big car repair bill looming you can split the cost with Bumper's 

Brake calipers have a moving and a static part, in order to apply braking pressure to the disc. If this movement is hindered by corrosion, a lack of grease, or simply a lack of use, the caliper can become stuck in the clamped position, effectively holding the brake on.

It happens mainly to rear brake calipers, as they often have a handbrake mechanism built in, too. But it can happen to either the front or rear.

The usual causes of a seized brake calliper are age or a lack of maintenance. Both the slider pins and brake piston are shielded from road dirt and water by rubber seals. If these are damaged during a repair or have degraded over time, they will no longer protect the piston or slider pins.

This leads to water and dirt entering, and subsequently both washing away lubricating grease, and allowing moisture in, which then corrodes vital components.

Once part of the slider pins or pistons have begun to corrode, they are difficult to separate or clean, and tend to bind or stick easily. 

If it’s the slider pins that have seized, they can, in some cases, be simply taken apart, cleaned up and re-lubricated. This can sometimes also be done to a slightly rusty brake piston. 

If the corrosion is too bad, and the parts are pitted or will not move freely, a new caliper will be required. Thankfully, these aren’t overly expensive, starting at around £90 for a small car, but rising to many hundreds for performance on luxury vehicles. 

When replacing a brake caliper, it is good practice to replace the brake pads, and if the seized brake has overheated, both the pads and discs should be replaced, on both sides.

Once the brake work has been done, the system will need bleeding. This is a good time to have your brake fluid flushed.

No, a caliper that is seized will not apply proper braking force, meaning your brakes will be unbalanced and potentially very poor. This is in addition to the fact that a seized caliper is likely to overheat and damage the discs, pads and even the caliper itself if not repaired soon enough.
