Frequently Asked Questions

AIR CONDITIONING SERVICE

Why does it need to be serviced?

Your air conditioning system can lose up to 15 per cent of its gas each year called natural leak, provided there is NO leak or problems with AC system (that means loss of half of the capacity within 3 years). Unless it's replaced the system will be less able to keep you cool and refreshed.

What happens if it's not serviced?

The system will continue to lose gas, become less efficient and lead to increased fuel consumption. It will eventually fail and need replacement parts.

What do we do?

We drain and recharge the system; check hoses, filters, belts and connections; and make sure the compressor and condenser are working correctly. We refill system with right amount of refrigerant and oil.

How often does it need to be serviced?

Volkswagen, Audi, Seat, Skoda and other major manufacturers recommend every 2 years.

BRAKE FLUID CHANGE

Why does my brake fluid need to be changed?

Brake fluid must withstand operating temperatures of up to 230°C but over time absorbs water which boils at 100°C. As the water boils, it turns to compressible vapour which means you won't be able to brake as efficiently.

What happens if it's not changed?

If too much moisture builds up, the brake fluid can boil while you're braking, seriously affecting performance. It can cause the brakes to fail. A spongy feel to the brake pedal shows you this has started to happen. Also moisture within the brake system causes corrosion to components.

What do we do?

We check the level and look for leaks. We drain the system and fill it with new brake fluid. We test the system and record it in your service book.

How often should it be changed?

At year 3 (for new vehicles) and every 2 years after that.

 

CAMBELT CHANGE

Why does my cambelt need to be changed?

The cambelt is one of the hardest working parts in your engine, driving major parts of the engine and keeping everything synchronised. Changing it prevents snaps, cracks and tears which in turn minimises the risk of major engine damage.

What happens if it's not changed?

The belt can go slack, making it snap or jump. This can cause severe damage to the engine. Your car will break down and could be very expensive to repair.

What do we do?

We strip down the relevant parts of the engine and renew the cambelt, cambelt tensioner and other rollers, idler etc. Then we reassemble the engine and road test your car. In most of the Volkswagen Group vehicles water pump is also driven by cambelt. So we also replace water pump along with cambelt kit as required by Volkswagen.

How often does it need to be changed?

About every 4 years or sooner for high mileage

 

DSG TRANSMISSION OIL AND FILTER CHANGE

Why does my DSG transmission oil and filter need to be changed?

This sophisticated piece of engineering needs regular oil changes. The smooth two-clutch system is computer-controlled with very fine engineering tolerances. If the gearbox oil is dirty it will damage the other parts and affect the performance.

What happens if it's not changed?

Dirty oil can overheat the gearbox or cause the clutches to burn out. This will lead to poor gear selection, loss of power and transmission failure.

What do we do?

We check the gearbox for leaks, drain it and replace the oil filter* before filling it with high quality gearbox oil to Volkswagen approved standards.
*Only on applicable vehicles

How often does it need to be changed?

The oil, every 40,000 miles, the filter may need to be changed as well.

 

REGULAR SERVICING

Why does my car need servicing?

Having your car serviced regularly will ensure it stays in peak condition, making sure you get optimum performance and endurance from all components.

What happens if it's not serviced regularly?

Your car's reliability and efficiency may be affected. And without a regular check, problems may go unnoticed, resulting in higher repair costs. Also, you don't get a Volkswagen Specialist stamp in your service book, which can affect the price that buyers are willing to pay for your car when you want to sell it.

What do we do?

Our Autotech trained technicians, using specialist tools and technology, carry out the recommended service, tailored to your car. We will replace the filters and lubricants specified and road test your car before recording the service in your service book.

How often does it need to be serviced?

Most Volkswagen, Audi Group Vehicles:            10,000 miles / 12 months
LongLife Servicing:                                                  when service indicator light is on

 

PETROL ENGINE SPARK PLUG REPLACEMENT

Why do they need to be changed?

Spark plugs operate in an extreme environment of high temperatures and high pressures. Over time they degrade and become less efficient.

What happens if they are not changed?

A powerful electric spark is needed to ignite the mixture of fuel and air in your engine. If a spark plug is used too long it is less able to ignite this mixture, leading to an inefficient engine and lack of performance. This can cause potential engine damage and means you use more fuel.

What do we do?

We remove the spark plugs from the engine, inspect them (they can tell us a lot about how your engine's performing) and replace them with new ones.

How often do they need to be replaced?

Every 40.000 miles or 4 years but on some engines 60.000 miles.

 

DIESEL FUEL FILTER REPLACEMENT

Why does my diesel fuel filter need to be replaced?

Your engine's fuel filter removes dirt, rust, water and other contaminants from the fuel entering the engine. It could become blocked if not serviced.

What happens if it's not replaced?

Clean fuel is vital for your car's engine to perform efficiently. Failure to replace the fuel filter when needed could lead to a drop in performance and could mean your car won't start.

What do we do?

We remove the filter from the fuel system and replace it with a new one.

How often does it need to be checked?

At the recommended age or mileage limit (usually every 40.000 miles if diesel fuel used is compliant with DIN EN 590 which is the case in the UK, otherwise every 20.000 miles)

 

AIR FILTER REPLACEMENT

Why does it need to be changed?

Your air filter stops dirt and dust particles entering the engine. Just like your vacuum cleaner, it needs to be kept clean to work properly.

What happens if it's not changed?

Fresh air is vital for your car's engine to perform well. If the air filter is not replaced when needed it could lead to a drop in performance as the engine tries to 'breathe' through a dirty filter. Your car could then be difficult to start.

What do we do?

We remove the old filter; check and clean the housing and hoses; then fit a new filter.

How often does it need to be changed?

At the recommended age or mileage limit (Usually every 60.000 miles if the vehicle is not subject to severe conditions such as road dust, fumes, off road, county roads etc.)

 

BRAKE PADS AND DISCS

Why do my brake pads and discs need to be changed?

When you brake, the brake discs that rotate with the wheels are gripped by brake pads, slowing the car down. Both discs and pads can become worn and corroded, so it's vital they are checked regularly for your safety.

What happens if they are not changed?

If your brakes aren't maintained regularly you won't be able to brake as efficiently. As well as reduced stopping power, worn or corroded brake parts can make your car vibrate and become really noisy.

What do we do?

We remove the wheels to visually check all the brake parts. We also measure the brake pad wear level. If the pads or discs are worn, corroded or warped we will let you know so we can arrange to replace them.

How often do they need to be checked?

At least once a year.

 

 BATTERY REPLACEMENT

Why does my battery need to be changed?

A fully charged battery supplies around 12.6 volts. If this falls to 12.0 volts, the state of charge drops from around 100% to around 25%. Conductivity is reduced by low temperatures, so if your battery is not holding its charge your car may not start in cold weather.

What happens if it's not changed?

Sludge builds up in the bottom of the case and can short the cell out. Deep discharges, heat, vibration, over-charging, under-charging or non-use all speed up the ageing process. In the end, if not replaced the battery will fail, and one day your car won't start.

What do we do?

We check the battery's ability to hold its charge using Bosch battery tester. We may need to replace the battery if it's not holding a charge, or look at why it's not charging when you drive.

How often does it need to be checked?

At every service

 

SHOCK ABSORBER REPLACEMENT

Why do my shock absorbers need to be changed?

Shock absorbers use hydraulic fluid to dampen the rebound of the suspension springs when you drive over a bump or hole. Without them your car would bounce around and be hard to control. A good shock absorber also prolongs the life of other suspension parts and drive systems such as the springs and tyres.

What happens if they are not changed?

If your shock absorbers fail your car will be very unstable and difficult to drive. A worn or leaking shock absorber can affect the safety of your braking and handling. No surprise then that they are a legal requirement and checked in your MOT test.

What do we do?

We check for worn and leaking shock absorbers whenever we service your car. If any one isn't working correctly we tell you it should be replaced.

How often do they need to be checked?

At every MOT test and service.

 

TYRE REPLACEMENT

Why do my tyres need changing?

At the right pressure, the compound rubber and scientifically cut tread patterns add to your car's handling and comfort. Too much wear will affect grip and safety as your car will become harder to handle. Incorrect tyre pressures and/or uneven tyre wear will also increase stopping distances in wet conditions.

What happens if they are not changed?

If your tyre tread is below the legal minimum depth of 1.6mm, your car won't pass an MOT test and you could be fined or get points on your license. But for safety reasons we recommend changing them before the legal limit is reached.

What do we do?

We check your tyres for pressure, tread depth and wear of the pattern. If they need replacing we have a range of different options in stock, depending on your car and type of driving.

How often do they need to be checked?

Every MOT test and service; and regularly by driver.
